compile->upload to fine tune my offset. It was a simple mistake in programming the menu. @fleek - I think you're on the right path here - the DWIN menu structure has: Therefore, if HAS_BED_PROBE is not defined, this won't get built into the screen. Scroll down and click one of the Macro buttons. Hopefully it will be added to the next nightly build. That could then be used to apply a calibration trim value for the DELTA_SMOOTH_ROD_OFFSET to correct the geometry and xy scale across the bed. Please ZIP up your Configuration.h and Configuration_adv.h files (as I some what expect to see 'outliers' when I start probing the the edge of the Print Radius. I don't want to throw out data. I don't have the code up and running yet on Delta's. (not retracting just printing) by a slight amount. @CRCinAU for configurations since its he keeps it private. I am trying to resolve this together with #18800, so it will take some time. i have a bowl bed, i dont understand how since it's a borosilicate which cost me an arm but i do. But the more I mess around with the High Resolution Mesh, the less convinced I am that we need the other flavors added in on top. But if that is what it takes to get the Grid Based running well, you can bet it will end up in the code! Marlin turns off the BEEPER pin as soon as it possibly can. I've also tuned the z-offset … I even cranked it all the way down to -6.72 without a bed crash. Viewed 12k times 4. Move Z down slowly until the probe triggers. Please open a new issue for related bugs. I have mine working now the way its supposed to be. Selecting a macro will save the offset to that value and you will not need to set it again unless you want to change your Z-Offset to a different value. I needed to swap my wires around for this also (grey to white spot). Would of prefered to level bed manually but was not given that option..is the dual the only version without the calibrate option? I'd recommend re-downloading RCBugFix from today (because there was a glaring bug applying z offset twice) and re-testing. my log of m111/g29/g28 and print then reset. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). At witch place in the delta levelling is LSF in use? And I'm still going to do that. Z offset not being saved (marlin 2.0) So still having trouble trying to get my bltouch going. We save the initial offset value to EEPROM, send the new offset value, using the g-code command M206 Z8, through the terminal; setting 8mm as the new home offset. or do i try another ? The sensor is meant to detect the bed before the nozzle touches the bed. We’ll occasionally send you account related emails. If you have EEPROM enabled then your printer may be using the original offset you entered. https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.0.x/Marlin/src/inc/Conditionals_LCD.h#L621, Here is where the actual Offset gets applied: https://github.com/thinkyhead/Marlin/tree/rc_final_z_correction. M851 Z-1.85 that determines the https://github.com/thinkyhead/Marlin/tree/rc_fix_leveling_maths, And this one adjusts Z based on the final probe position: #define Z_PROBE_OFFSET_FROM_EXTRUDER 0. For my 3d printer, the initial home offset will be 8mm; because I allowed about 10mm for home offset when setting Z_MAX_POS in the Marlin firmware. do i have to bother ? lwaynej perhaps you should start a new bug report by the looks of your issue. If you made the changes in configuration.h and uploaded you need to send M502 followed by M500 to update and save the new settings. When auto bed leveling is concerned, hardware selection seems to get all the attention. is there a way to not manually reconfigure the configs.h files ? I suspect this is a configuration issue. This is the vanilla version of Marlin Firmware 2.x pre-configured for Creality Ender 3 printers with original or generic BL Touch sensors. In this case the head is moving in a parabolic shape which will also have the effect of an xy scaling problem near farther away from the center. This turned out to be a simple menu programming error of the menu. Many thanks for all your work on this. I'm using a Prusa clone with Ramps 1.4, Marlin 1.1.5 and an inductive proximity sensor Z-probe. My printer uses the SKR 1.4 and I use a BLTouch for the Z endstop (I am not using bed leveling at this point, it is turned off in the printer settings.) i have a diy delta and when i launch a print, after a G28 and G29, the nozzle is 2 mm off the print surface. Z has to be accurate and has to be adjusted quite accurately. @brainscan Yeah - the units here are in mm - the marlin limitation is +/- 10mm by default, and adjustable in 0.01mm increments. Bug Description z-offset does not change live when using the tuning menu. Once you leveled with the paper, you do not need to create an offset to account for the paper thickness, however, there are purists that do that. No. You signed in with another tab or window. I have diff'd Configuration.h and Configuration_Adv.h between the working and none working builds and the only differences occur in things that changed between the two releases. The z offset … Mainly all similar to this below: Hi ultimakers, i want to print directly onto different objects which have a height of 1, 3 and 4 mm. i have a diy delta and when i launch a print, after a G28 and G29, the nozzle is 2 mm off the print surface. So is the autolevel useful or not ? Marlin just release v1.1.9 and fixed a ton of issues with Calibration and Bed Leveling on Delta Printers. But once I get the Delta's up and running, I'm going to bring up the Grid Based ABL correction on top of the High Resolution Mesh correction. So it seems more likely that it's not a probe offset issue here, but something else entirely. Having looked at #19384 I believe the fix is actually in the Marlin Dwin file which at the moment is just a work in progress. The High Resolution Mesh is the Cat's Meow for 3D-Printer Bed Leveling. Keep tuning. Is there a way in cura to set the z value, so that the starting z-value is 1,3 and 4 mm above the printbed. setting z-offset works and you can save it but the live tuning adjustments dont. Lower Z-Offsets are 0.8 and 0.9. My code is now based on 2.0.6 (84b96d3) and the Z probe offset no longer appears to work. requested in the Issue template) and drop them into your next reply. ^^. Baby stepping via commands works so I know it does that. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The offset is not stored in EEPROM AFAIK and there's no z-offset in this Marlin version. i'll be around, but not near my delta. Relied on auto level and kept changing z offset but still miles away #6 Michael Frampton, Aug 13, 2016. Just in case. I gave the branch the name 'Unified Bed Leveling' because it was my intention to bring together all of the different Auto Bed Leveling ideas for all flavors of printers. Has this been added to the nightly builds yet? This number will always be a negative value—the closer your Z-offset is to zero, the further away from the print surface the hot end nozzle will be moved. It would be prudent to do an M48 where ever on the bed you home the Z-Axis. Anyway, it should be noted that actually the probe offset doesn't matter in bed leveling, because all G29 does is determine the tilt of the bed. I do a g28 then g29 g1x100y100 f5000 then manually set Z tll it just barely touches paper.

Because, if it doesn't have good repeat ability, we will never get this resolved. The error from any point is squared, so in a sense, it is exponential. Marlin Zprobe offset not working. If it works I will push the fix to the main repo. ( 5.2 => -5.2) Set with M851 Z-5.2 and #define Z_PROBE_OFFSET_FROM_EXTRUDER -5.2. The config.h file is the stock file that comes with marlin, with the only significant change being the offsets for the capacitive sensor (x=0, y=52, z=5). i will postthe results soon. see here. Sign in It is the offset that you define with command M851 e.g. Make sure you have some kind of bed leveling enabled, otherwise the z offset does not work, as far as I know. @Nocturnal42 I notice that your probe triggers regularly when your nozzle is at least 1.8mm above the bed, implying that the correct probe offset for your setup is closer to -1.8 than -5.00 as shown. From RepRap. I calculated the offset (-2.98). Use that bat file to open the project and flash your image.Test the BLTouch with your finger again. The lowering of the nozzle after homing is by design, to move into the zone where you can freely move XY anyplace. So no more leveling nor fiddling with the Z offset! @cosmoderp Can you please add to the title '[Bug] Ender 3V2' so that it can be identified specifically, because I think this problem is specific to Ender 3V2 because of the DWIN DGUS controller. I keep forgetting that the probe Z offset has nothing to do with the Z position when printing, unless one is using their Z probe for homing. If EEPROM_SETTINGS is enabled, the home offsets are saved with M500, loaded with M501, and reset with M502. Does not seem to have fixed it for me. The home offset is persistent — added to the current position until changed. It is also used by the Z-Baby-Stepping. @fleek just tested it ... sorry had gone to work. Now matter what I see the offset to in the menu the distance between the nozzle and the bed are about -2.23 after auto home and moving Z to 0. then there are 4 reasons for this issue according to me:-) 1.improper offset distance between nozzle and probe might be entered in marlin 2.unwanted play of probe mount during probing 3.or firmware issue(bug or improper bed leveling settings 4.there can be a noise in the probing signal due to any ac voltage near the signal wire which can be the reason for wrong triggering values — You are … 4) for some - plug the z-stop connector from the bltouch into the remaining two pins (this did not work for me - but it worked for others) 5)for me - plug into the normal z-stop header like one would have on an ender 3 V1. Configurations, please Marlin indicates this by blinking question-marks in place of X, Y and Z on the LCD screen (v1.1.8 and older) or blinking ‘?’ in place of the coordinates besides X,Y and Z (Marlin v1.1.9 / v2.0.0 and newer). https://www.youtube.com/watch?v=6C7-YI-uQ9s. using current firmware. Now turn off the software endstop temporarily (with M211 S0) to enable lowering the nozzle further down to the bed. My printer is an Anet A8 with Marlin firmware, I was having issues with the autoleveling sensor and reset the Z offset to 0 and let G29 get the mesh offsets and its working good now. i have read your posts and will consider all of them. The only thing can go is to have the physical nozzle below the bed. But by the same token, that may be the right answer to get a good plane defined in the event some dirt or plastic pieces end up under the glass. The standard configuration file from Marlin distribution was carefully reviewed to include the latest Ender 3 specific settings from … To measure an offset between a trigger point and the bed, lower the nozzle to the trigger point (by homing, if it’s the homing device), and note the z-value. I'm running Marlin 1.1.9 (and I have tried to reflash Marlin with fresh settings). @Roxy-3D Most of those probed points seem fine to me. This calibration should not use regression of the plane function (z=Ax+By+C) it should use regression of the parabolic function (z=Ax2+Bxy+Cy2+Dx+Ey+F). After homing and using "Move Axis" to set my Z to 0 I am still 2.22 mm above where I want it to be. The Z probe offset is being ignored. possible. M851 followed by your offset you noted down in the last step, in the photo above the command would be M851 Z0.00 but yours will look more like M851 Z-0.90. and it should be around 4ish mm when bed crash. i think with DWIN_SET? The only issues I had with the above process is it can get confused if you do some of it on the control panel and some of it on a tethered PC/octoprint, as the printer does not … Nothing in the title or description indicated this was an Ender 3 V2 or that it was DWIN. Just make sure that the G29 command comes after the very last G28 command in the script. Also to verify movement I both watched the motor and light laid my finger on the spindle to detect even the slightest movement. However, at “user level” in the LCD menus, we refer to the first extruder as E1, the second as E2, etc. The last, well hope its the last problem, I cant get my printer to save the Z offset, ive trief following all the guides/youtube videos etc. im almost sure that EEPROM is on, if i undertood well what it is. The DWIN DGUS controller is still an unknown to me as well, as to the tools required and how the marlin firmware interacts with it. But you have to fine-tune (calibrate) the values in the start-script anyway (with M218), or do you plan to customize the firmware after every nozzle change? I need some suggestions for a z offset issue. Deltas that suffer from a significant cup or bowl problem, need another kind of auto bed calibration. Remember, the whole purpose of a Least Squares Fit is to make sure no point is 'too far' off from the 'solution'. It looks like there are configs attached now and someone is already trying to help, so hopefully something can be figured out. Expected behavior: when you adjust the z-offset while printing the z-offset should change. The Z offset should be specified as exactly as possible using a decimal value. But let me help you understand why I'm being slow accepting the ideas. i have found drop sagment, replaced it and add one to 5, no changement. After powering up a 3D printer the printer’s controller board does not know at which position its axes are. Enable DEBUG_LEVELING_FEATURE and issue the command M111 S255 before doing a G28 and G29. New to the forum, not that new to 3D printing. One 'bad' point, especially, if it it is off a bunch, will pull things much more than it 'should' in that direction. At the moment I am using the EZABL's version of Marlin on a Bigtree tech e3 mini v2 anyone any ideas I figured out why this was not working on my ender 3 v2 todays perhaps you have a new bug. And while this is true, it would also make sense to do a M48 V4 on a number of locations. if there are changes to the main config file though and I was meant to simply make all the needed changes myself be advise. So, for example to change the z offset for the probe to -7.5 you would use M666 P-7.5. :) thanks by advance. Posted by BrokePilot . To set the Z axis home offset on the 3d printer, you will use g-code commands including M206 for the home offset, M500 and M501 for the Marlin Firmware EEPROM feature, and G1 for controlled … I was having some resolution and memory problems with RepG and moved onto Simplify3D. It would appear that the z-offset functionality is broken under 3.4.1 as changing the value does not seem to affect the print in any way nor could I find anything in the g-code file that would suggest it is working. I was at 13.4mm on z offset on marlin. You should have an option called Record to EEPROM, as long as you have supported it in your Marlin. Changing the Z offset allows you to fine-tune the Z=0 position by exact values, not putzing with a mechanical setting that can make things worse. :). In addition to that be sure you followed ALL the steps of the installation guide (especially the sensor calibration, Z offset, and the slicer settings (starting code is essential, use the one in the guide)). Long Beep on Boot. is there a way to not manually reconfigure the configs.h files ? For my 3d printer, the initial home offset will be 8mm; because I allowed about 10mm for home offset when setting Z_MAX_POS in the Marlin firmware. I wouldn't be surprised if there are repeat-ability issues when you are probing near the edge of the bed. Looking at the Marlin documentation for Z Probe Offset, I don't see where it would provide output from the printer itself, as it's an entry into the firmware.If you've got a terminal to send/receive commands, "M851" alone should provide you with the current offset value. https://www.youtube.com/watch?v=6C7-YI-uQ9s, https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.0.x/Marlin/src/inc/Conditionals_LCD.h#L621, https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.0.x/Marlin/src/lcd/dwin/dwin.cpp#L1090, Fix for setting offset from tune menu (ender 3 v2). I'm using the Ender 3 stock mainboard, Bltouch is mounted using the Petsfang v2 and in Marlin 1.1.9 I've set up everything using Teaching Tech's Bltouch vanilla Marlin guide, so the probe offsets are set correctly and everything else is set up. If you are using our latest Marlin 1.1.8 firmware, you can adjust the z-offset with the babystep z function. This is a hardware issue due to the connected beeper pin being HIGH when the board is first powered. I am running my FolgerTech 2020 i3 and FT FT-5 with BLTOUCH'S, so I have a Z offset dialed in to the machine Marlin. Yes. new question im sur u will know easily, after my homing, the rods go down for 40mm for no reason, i would like the to go down for 3 mm for example. In general, on deltabots the probe should be connected to the unused Z-Min endstop pin (if there is one). Changing the machine name would have no affect over it reading from EEPROM or not. see. The text was updated successfully, but these errors were encountered: What version of Marlin are you using? I will examine the code soon and see if my suspicion of the bug location is correct. Michael Frampton Well-Known Member. is at the bottom and setting z offset to 0.3 would mean that after. Looks like we have to wait a while longer for this to be released. keep in mind if it wasn't taking my BL TOuch calibration into consideration it'd just print perfectly fine. After that is calculated and applied you do another probe of the entire bed and regression to the plane function to correct any remaining tiny Z offsets. Procedure to … At the very end of the log, notice that the correction to Z only amounts to -0.06mm (From 15.00 to 14.94), not enough to mess with the first layer assuming a more-or-less flat bed. @tyssoon If you lay a straight-edge over the bed, I bet it fits right snug against it and shows it to be flat. Higher Z-Offsets are 1, 1.1 and 1.2. Tuning a delta is tricky, but when out of tune, the height at center and at the edges will differ. i have to sand a bit my effector to be sure that i can print. Dunno if thinkyhead still has this printer and might be able to say its just me alone having this issue anyway. It turned out that creality made a mistake when designing the menu. thanks for your help. @Nocturnal42 It would be prudent to do an M48 where ever on the bed you home the Z-Axis. I am running marlin 1.1.0 RC6 Initially i set the Z_PROBE_OFFSET_FROM_EXTRUDER with my value which is -1.3 To adjust your Z-Offset, go into MatterControl under the CONTROLS tab. The Z-axis offset, or Z-offset for short, is the distance from the top of the heated bed washers (defined as “zero”) to the tip of the hot end nozzle. Using x and y will change the endstop offsets. Have a question about this project? to your account. The High Resolution Mesh capabilities are impressive. 2 $\begingroup$ I need to set a Z offset for the Flying bear P902. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. When you power up it displays the settings that are being used so you can easily verify if things are changing or not. My probe offset is about -2.22. Configuring Marlin Bed Dimensions. the issue I have is the z offset not changing anything. It is not a problem that the sensor is not above the build plate during printing as long as it is above the build plate during the auto bed levelling sequence.. Homing does not necessarily need to be the (0,0) coordinate. homed the nozzle is far from bed, but issuing command to z0 is not. Sorry if it hasn't helped but did you do m500 m502 or m502 m500? Check the Z position on the printer screen, and subtract another 0.1 from this value to account for the thickness of the paper. For example, if the switch trips when the platform is 3 mm below the nozzle, you set the Z offset to +3.0 (or maybe -3.0, your mileage may vary), so that the Z=0 position corresponds to the nozzle tip. Please note that starting scripts may vary from one printer to another. At which place in the delta levelling is LSF in use? I have the following settings in my config: #define X_PROBE_OFFSET_FROM_EXTRUDER 25 #define I was at 13.4mm on z offset on marlin. I did a pull request today.....sorry it took so long I had to learn how to use git. I measured the offset to .5mm by placing the nozzle on the bed and going up … I am using EZABL and run G28,G29 I have read somewhere that there was a bug within Marlin i thought this had been fixed in the latest version. i.e., 680 instead of 682. i dont understand what the z offset is for so ^^. My setup with level issues: Dear @tyssoon where is the place in marlin where i can change that please. Note the z again. You signed in with another tab or window. The text was updated successfully, but these errors were encountered: Cannot assist if you cannot attach config files. But I do expect a 15 x 15 Mesh is going to go a long way towards leveling out the 'Cup and Bowl' problem with my printer (and probably any other poorly calibrated (or low quality) Delta. I have the z-offset plugin installed and am running cura 3.4.1 under Ubuntu 18. but u were right, i tuned z home pos to 685 and now it's okay i can print. swapped the config.h and obtained that in the rcbugfix. Download files and build them with your 3D printer, laser cutter, or CNC. I have configured #define NOZZLE_TO_PROBE_OFFSET { 0, -41, -2.22}. When I try to "set home offset" on the printer I get "Error: too far from refrence point". M500 then m502, no results. [Bug] Ender 3V2 z-offset tuning not working. cosmoderp changed the title z-offset tuning not working [Bug] Ender 3V2 z-offset tuning not working Jul 28, 2020. This will store all the current settings in your EEPROM permanently. m500+m502 have changed nothing, so i think this is not an eeprom problem. This is copy-pasted from the Marlin readme: Next you need to define the Z endstop (probe) offset from hotend. Check your Z endstop trigger: EZABL – Z Not Showing “TRIGGERED” M119 Test i will test what happen with a G29 before. Z homing was not working at all until I uncommented "USE_PROBE_FOR_Z_HOMING". I put 5mm on marlin on z offset to be sure, and same thing, 2mm. privacy statement. @Roxy-3D While the printer is printing the skirt, you will adjust the Z Probe Offset. @tyssoon All my examination of the code shows that the value being used is the one stored in the variable zprobe_zoffset as set by M851. Slice the STL file with your desired settings and print it on your printer. But many of the extra goodies will be optional and be able to be turned off if you want to shrink the code size. Bltouch not working properly. #define X_MAX_POS 200 #define X_MIN_POS -45 #define Y_MAX_POS 170 #define Y_MIN_POS -20 #define Z_MAX_POS 130 #define Z_MIN_POS 0 apparently was having no effect previously. I'll get all flavors of Auto Bed Leveling working for all types of printers. Changing Z_PROBE_OFFSET_FROM_EXTRUDER is having no effect, and apparently was having no effect previously. Let's make sure your probe 'repeats' well enough that it isn't causing problems. I put 5mm on marlin on z offset to be sure, and same thing, 2mm. The Z offset can be overridden with M851 Z … Tuck into this detailed guide of setting up Marlin for auto bed leveling to make sure that that shiny new probe actually works! Sign in Using RCBugFix from about 12 hours ago. But, every time when I try to input this … If it crashes in to the bed, try to do Note #2 above. The honest truth is, if you have the High Resolution Mesh, you don't need anything else. Ask Question Asked 1 year, 8 months ago. It doesn't matter if I set the values to positive or negative. Some uses include fine adjustment of Z position (without moving endstops) and shifting the coordinate space to print on a different part of the bed. If you have a delta its much more likely you calibration is off, then the bed is not flat. I have been working on a menu and hope to push out a fix soon. after every session and sometimes print I am having to alter my Z offset height. The easiest way to tune the homed height is to simply do homing, then move the nozzle all the way down to the bed, and if it isn't zero, adjust the z home position by the difference. We’ll occasionally send you account related emails. Changing the home offsets will not invalidate bed leveling or other saved data. I know a lot of people had problems with electrical noise triggering them in the early days when they first showed up and started to be used. I'm beginning to wonder, myself. Installation went without a hitch. Using the configuration menu I have set the offset to -4.44 and I am still 2.22 mm above where I want the axis to be. Now with Cura, it drops to Z=0 but never drops the offset amount before starting to print. If not maybe robust regression should be considered to reduce the effect of signal noise specially when using z probe designs that induce noise into the measurements. No it doesn't throw out any outliers. First, re-download the latest RCBugFix which has the most logging. This is a guide to using g-code command M206 to set the Z axis home offset in the Marlin Firmware, a guide to a method of adjusting the gap distance between the hot end nozzle and the build platform. …as you can see if you look at the (unaltered) Configuration_adv.h file. G-Code Z offset not working. Follow these steps to change your Z-offset.. (the offset number you use will depend on what M212 is currently set to and how much you need it to move) 1. enter the command "M212 Z-1" to lower your Z axis offset to -1mm. If you can’t find it, you can alternatively run the command M500 (Save settings). I also just found that there was an option that lets you change the z-offset with the babysteps that I might turn on. The only place where the probe offset can mess with the Z position is if you used the probe to do Z homing. The X and Y offsets are specified as integers. The current position is adjusted to align to the new home offset values. Rich // Does not require M206 and indeed required M206 to be clear. M502 M500. I have the same issue with my Marlin printers. Then I issued a M851 Z0.3 to set a z_offset so the printer would lay it's 1st layer a little bit above the bed, but no matter what I set the z_offset to, the printer always goes to the same position with G1 Z0 even after G28 and tries to print on the same z_height scraping the bed, even if I give z_offset … That's pretty much always how I adjust mine. I've had to resort to repeatedly modify->compile->upload to fine tune my offset. It was a simple mistake in programming the menu. @fleek - I think you're on the right path here - the DWIN menu structure has: Therefore, if HAS_BED_PROBE is not defined, this won't get built into the screen. Scroll down and click one of the Macro buttons. Hopefully it will be added to the next nightly build. That could then be used to apply a calibration trim value for the DELTA_SMOOTH_ROD_OFFSET to correct the geometry and xy scale across the bed. Please ZIP up your Configuration.h and Configuration_adv.h files (as I some what expect to see 'outliers' when I start probing the the edge of the Print Radius. I don't want to throw out data. I don't have the code up and running yet on Delta's. (not retracting just printing) by a slight amount. @CRCinAU for configurations since its he keeps it private. I am trying to resolve this together with #18800, so it will take some time. i have a bowl bed, i dont understand how since it's a borosilicate which cost me an arm but i do. But the more I mess around with the High Resolution Mesh, the less convinced I am that we need the other flavors added in on top. But if that is what it takes to get the Grid Based running well, you can bet it will end up in the code! Marlin turns off the BEEPER pin as soon as it possibly can. I've also tuned the z-offset … I even cranked it all the way down to -6.72 without a bed crash. Viewed 12k times 4. Move Z down slowly until the probe triggers. Please open a new issue for related bugs. I have mine working now the way its supposed to be. Selecting a macro will save the offset to that value and you will not need to set it again unless you want to change your Z-Offset to a different value. I needed to swap my wires around for this also (grey to white spot). Would of prefered to level bed manually but was not given that option..is the dual the only version without the calibrate option? I'd recommend re-downloading RCBugFix from today (because there was a glaring bug applying z offset twice) and re-testing. my log of m111/g29/g28 and print then reset. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). At witch place in the delta levelling is LSF in use? And I'm still going to do that. Z offset not being saved (marlin 2.0) So still having trouble trying to get my bltouch going. We save the initial offset value to EEPROM, send the new offset value, using the g-code command M206 Z8, through the terminal; setting 8mm as the new home offset. or do i try another ? The sensor is meant to detect the bed before the nozzle touches the bed. We’ll occasionally send you account related emails. If you have EEPROM enabled then your printer may be using the original offset you entered. https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.0.x/Marlin/src/inc/Conditionals_LCD.h#L621, Here is where the actual Offset gets applied: https://github.com/thinkyhead/Marlin/tree/rc_final_z_correction. M851 Z-1.85 that determines the https://github.com/thinkyhead/Marlin/tree/rc_fix_leveling_maths, And this one adjusts Z based on the final probe position: #define Z_PROBE_OFFSET_FROM_EXTRUDER 0. For my 3d printer, the initial home offset will be 8mm; because I allowed about 10mm for home offset when setting Z_MAX_POS in the Marlin firmware. do i have to bother ? lwaynej perhaps you should start a new bug report by the looks of your issue. If you made the changes in configuration.h and uploaded you need to send M502 followed by M500 to update and save the new settings. When auto bed leveling is concerned, hardware selection seems to get all the attention. is there a way to not manually reconfigure the configs.h files ? I suspect this is a configuration issue. This is the vanilla version of Marlin Firmware 2.x pre-configured for Creality Ender 3 printers with original or generic BL Touch sensors. In this case the head is moving in a parabolic shape which will also have the effect of an xy scaling problem near farther away from the center. This turned out to be a simple menu programming error of the menu. Many thanks for all your work on this. I'm using a Prusa clone with Ramps 1.4, Marlin 1.1.5 and an inductive proximity sensor Z-probe. My printer uses the SKR 1.4 and I use a BLTouch for the Z endstop (I am not using bed leveling at this point, it is turned off in the printer settings.) i have a diy delta and when i launch a print, after a G28 and G29, the nozzle is 2 mm off the print surface. Z has to be accurate and has to be adjusted quite accurately. @brainscan Yeah - the units here are in mm - the marlin limitation is +/- 10mm by default, and adjustable in 0.01mm increments. Bug Description z-offset does not change live when using the tuning menu. Once you leveled with the paper, you do not need to create an offset to account for the paper thickness, however, there are purists that do that. No. You signed in with another tab or window. I have diff'd Configuration.h and Configuration_Adv.h between the working and none working builds and the only differences occur in things that changed between the two releases. The z offset … Mainly all similar to this below: Hi ultimakers, i want to print directly onto different objects which have a height of 1, 3 and 4 mm. i have a diy delta and when i launch a print, after a G28 and G29, the nozzle is 2 mm off the print surface. So is the autolevel useful or not ? Marlin just release v1.1.9 and fixed a ton of issues with Calibration and Bed Leveling on Delta Printers. But once I get the Delta's up and running, I'm going to bring up the Grid Based ABL correction on top of the High Resolution Mesh correction. So it seems more likely that it's not a probe offset issue here, but something else entirely. Having looked at #19384 I believe the fix is actually in the Marlin Dwin file which at the moment is just a work in progress. The High Resolution Mesh is the Cat's Meow for 3D-Printer Bed Leveling. Keep tuning. Is there a way in cura to set the z value, so that the starting z-value is 1,3 and 4 mm above the printbed. setting z-offset works and you can save it but the live tuning adjustments dont. Lower Z-Offsets are 0.8 and 0.9. My code is now based on 2.0.6 (84b96d3) and the Z probe offset no longer appears to work. requested in the Issue template) and drop them into your next reply. ^^. Baby stepping via commands works so I know it does that. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The offset is not stored in EEPROM AFAIK and there's no z-offset in this Marlin version. i'll be around, but not near my delta. Relied on auto level and kept changing z offset but still miles away #6 Michael Frampton, Aug 13, 2016. Just in case. I gave the branch the name 'Unified Bed Leveling' because it was my intention to bring together all of the different Auto Bed Leveling ideas for all flavors of printers. Has this been added to the nightly builds yet? This number will always be a negative value—the closer your Z-offset is to zero, the further away from the print surface the hot end nozzle will be moved. It would be prudent to do an M48 where ever on the bed you home the Z-Axis. Anyway, it should be noted that actually the probe offset doesn't matter in bed leveling, because all G29 does is determine the tilt of the bed. I do a g28 then g29 g1x100y100 f5000 then manually set Z tll it just barely touches paper.
