i.e., 680 instead of 682. i dont understand what the z offset is for so ^^. For instance, we changed the Z_RAISE_* options into Z_*_HEIGHT options, so Z_OFFSET_FROM_EXTRUDER offset is no longer used to ensure a minimum height before/between/after probing. Example: The feature is available in the newest Marlin firmware. I will keep your idea of throwing out points that are too far off the plane defined by the other points in my back pocket. #define Z_PROBE_OFFSET_FROM_EXTRUDER 0. 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. Mon Sep 19, 2016 8:46 pm . I also just found that there was an option that lets you change the z-offset with the babysteps that I might turn on. Once you have made the offset settings, don’t forget to save the value in memory. Personally, I've noticed that using M581 to change the offset does not actually work with G29, even after M500 and M503 to verify, it still uses the default Z_PROBE_OFFSET_FROM_EXTRUDER offset regardless of what you set it to. But if that is what it takes to get the Grid Based running well, you can bet it will end up in the code! There's one outlier, which triggers the probe earlier, at 2.3, a half-millimeter higher than the other probes. 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. Previously it did a fast probe to figure out where it was at and then a slow probe for accuracy (I don't see an obvious way to change this.) and it should be around 4ish mm when bed crash. I have configured #define NOZZLE_TO_PROBE_OFFSET { 0, -41, -2.22}. @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. By clicking “Sign up for GitHub”, you agree to our terms of service and https://github.com/MarlinFirmware/Marlin/blob/bugfix-2.0.x/Marlin/src/lcd/dwin/dwin.cpp#L1090. I even cranked it all the way down to -6.72 without a bed crash. The z offset … This issue has been automatically locked since there has not been any recent activity after it was closed. The Z offset should be specified as exactly as possible using a decimal value. First, re-download the latest RCBugFix which has the most logging. Because, if it doesn't have good repeat ability, we will never get this resolved. No. Yes it indicates, but it ignores it. 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. 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. Marlin turns off the BEEPER pin as soon as it possibly can. The text was updated successfully, but these errors were encountered: What version of Marlin are you using? :) thanks by advance. The current position is adjusted to align to the new home offset values. thanks for your help. @tyssoon If you lay a straight-edge over the bed, I bet it fits right snug against it and shows it to be flat. 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. The Z offset can be overridden with M851 Z … I have the following settings in my config: #define X_PROBE_OFFSET_FROM_EXTRUDER 25 #define after every session and sometimes print I am having to alter my Z offset height. Enable DEBUG_LEVELING_FEATURE and issue the command M111 S255 before doing a G28 and G29. // Does not require M206 and indeed required M206 to be clear. Once you start a print and babystep z to the correct height, navigate to Menu>Control>Store Settings.This will store the babystep adjustment to use on future prints. 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. After powering up a 3D printer the printer’s controller board does not know at which position its axes are. Already on GitHub? 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. Z homing was not working at all until I uncommented "USE_PROBE_FOR_Z_HOMING". if there are changes to the main config file though and I was meant to simply make all the needed changes myself be advise. i changed it to 11mm and the nozzle were still at 2 mm above the bed. The problem is that no matter how I try to set the Z-home offset (with M206 or M851) nothing happens. Keep tuning. Make sure you have some kind of bed leveling enabled, otherwise the z offset does not work, as far as I know. i will test what happen with a G29 before. ( 5.2 => -5.2) Set with M851 Z-5.2 and #define Z_PROBE_OFFSET_FROM_EXTRUDER -5.2. I suspect this is a configuration issue. 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. The M206 offsets can be saved to EEPROM too, so you only need to change them if there is some change in your printer hardware. I mean it was the ender 3 v2 using DWIN and I was nice enough to provide a video. I was at 13.4mm on z offset on marlin. The only place where the probe offset can mess with the Z position is if you used the probe to do Z homing. And I'm still going to do that. my attempt was: const int MIN_STEPS_PER_SEGMENT = 6; not so far ! 2 $\begingroup$ I need to set a Z offset for the Flying bear P902. The X and Y offsets are specified as integers. 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). To adjust your Z-Offset, go into MatterControl under the CONTROLS tab. Posted by BrokePilot . It was a simple mistake in programming the menu. A word of warning: be very careful with Z homing with this mod, as if you are already below the Z endstop and you try to home Z, the bed will crash into the extruder. see. to your account. Thingiverse is a universe of things. Marlin provides reasonable defaults, but they will not apply to every situation. If you can’t find it, you can alternatively run the command M500 (Save settings). i'll be around, but not near my delta. Usually, a printer homes on the endstop switches, from that coordinate an offset is defined in the firmware to move to the origin. @cosmoderp I am not sure about the units, but I think when you dial in 10, it will only move like 10/100 or 0.1mm, so you might want to dial in more to test. homed the nozzle is far from bed, but issuing command to z0 is not. my log of m111/g29/g28 and print then reset. From RepRap. The High Resolution Mesh is the Cat's Meow for 3D-Printer Bed Leveling. Post the log output here so we can see what's going on. Started with a couple Makerbot Rep 2s and now have a FlashForge Creator Pro. Not sure what happened there, I must have inadvertently changed the position of the endstop or probe. setting z-offset works and you can save it but the live tuning adjustments dont. I put 5mm on marlin on z offset to be sure, and same thing, 2mm. so the rcbugfix is still bugged ? When I try to "set home offset" on the printer I get "Error: too far from refrence point". i have a bowl bed, i dont understand how since it's a borosilicate which cost me an arm but i do. 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 it crashes in to the bed, try to do Note #2 above. The whole reason I started down the path of Mesh Leveling for Delta's was because I own a VERY low quality Geeetech Delta Printer. So is the autolevel useful or not ? Yes. The "paper drag" method is perfect for determining the correct Z level. Active 1 year, 8 months ago. If it works I will push the fix to the main repo. By clicking “Sign up for GitHub”, you agree to our terms of service and I understand what you are saying. Set #define Z_PROBE_OFFSET_FROM_EXTRUDER -.75 // Z offset: -below +above [the nozzle]. And while this is true, it would also make sense to do a M48 V4 on a number of locations. swapped the config.h and obtained that in the rcbugfix. Z offset not being saved (marlin 2.0) So still having trouble trying to get my bltouch going. So no more leveling nor fiddling with the Z offset! https://github.com/thinkyhead/Marlin/tree/rc_fix_leveling_maths, https://github.com/thinkyhead/Marlin/tree/rc_final_z_correction, https://github.com/MarlinFirmware/Marlin/blob/RCBugFix/Marlin/Marlin_main.cpp#L3240-L3243. see here. Have a question about this project? Looks like we have to wait a while longer for this to be released. Bug Description z-offset does not change live when using the tuning menu. Many thanks for all your work on this. 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). Long Beep on Boot. Have a question about this project? But do you think that one outlier is throwing anything off? Nothing in the title or description indicated this was an Ender 3 V2 or that it was DWIN. Make sure you that you reset the eeprom, save it, then powercycle first. Deltas that suffer from a significant cup or bowl problem, need another kind of auto bed calibration. Configurations, please I do a g28 then g29 g1x100y100 f5000 then manually set Z tll it just barely touches paper. Printers without a cup or bowl potential (or delta printers if they are known to have minimal (less than 0.1mm) cup or bowl issue) can use robust regression to a plane. Download files and build them with your 3D printer, laser cutter, or CNC. Yes. Just in case. I change the "#define CUSTOM_MACHINE_NAME" everytime i make a modification, to be sure the firmware is good just looking at the screen, so i think it's ok. Do i say nonsense ? Tuning a delta is tricky, but when out of tune, the height at center and at the edges will differ. My setup with level issues: Move Z down slowly until the probe triggers. Sign in privacy statement. to your account. Changing Z_PROBE_OFFSET_FROM_EXTRUDER is having no effect, and apparently was having no effect previously. M428 sets home offsets so the current position aligns to the native home position. Using RCBugFix from about 12 hours ago. Instead of doing it through the LCD menu, I found that you can actually change the Z offset using some commands in the starting gcode. It would be prudent to do an M48 where ever on the bed you home the Z-Axis. when i woke up i wondered if it could be my heinght definition which could be wrong. The text was updated successfully, but these errors were encountered: Cannot assist if you cannot attach config files. I am not rejecting those thoughts. 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. You signed in with another tab or window. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. G-Code Z offset not working. Just make sure that the G29 command comes after the very last G28 command in the script. 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 … If you are using our latest Marlin 1.1.8 firmware, you can adjust the z-offset with the babystep z function. 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. Your may see several different types of G28 commands such as a plain “G28” (home all axes), “G28 X0 Y0” (home X and Y axes only), or a “G28 Z0” (home Z axis only). On machines that use Z-min for an endstop, the Z-Max pin is recommended next, so … Successfully merging a pull request may close this issue. Is this an 'inductive' probe? 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 made the changes in configuration.h and uploaded you need to send M502 followed by M500 to update and save the new settings. i dont understand what the z offset is for so, z_offset if primarily for the Mesh Bed Leveling schemes to adjust the distance from the Mesh to the nozzle. I wouldn't be surprised if there are repeat-ability issues when you are probing near the edge of the bed. If you are not using Mesh Bed Leveling, just set it to 0.000. At the moment I am using the EZABL's version of Marlin on a Bigtree tech e3 mini v2 anyone any ideas This will be your new Z-Probe Offset value; Set the nozzle temperature back to 0 with M104 S0; Set your new Z-Probe Offset using M851 Z, for example M851 Z-2.2; Re-enable the soft movement limits using M211 S1 I don't have the code up and running yet on Delta's. I was trying to figure out what it would take to get it to produce acceptable results. (not retracting just printing) by a slight amount. In general, on deltabots the probe should be connected to the unused Z-Min endstop pin (if there is one). m500+m502 have changed nothing, so i think this is not an eeprom problem. Personally, I've noticed that using M581 to change the offset does not actually work with G29, even after M500 and M503 to verify, it still uses the default offset regardless of what you set it to. M851 Z-1.85 that determines the However, at “user level” in the LCD menus, we refer to the first extruder as E1, the second as E2, etc. @Roxy-3D Lower Z-Offsets are 0.8 and 0.9. 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 … Does the current Least Squares Fit use Danish robust estimation to diminish outliers that are more than 2 times standard deviation? i have to sand a bit my effector to be sure that i can print. but u were right, i tuned z home pos to 685 and now it's okay i can print. You signed in with another tab or window. One 'bad' point, especially, if it it is off a bunch, will pull things much more than it 'should' in that direction. I figured out why this was not working on my ender 3 v2 todays perhaps you have a new bug. 11Mm and the nozzle touches the bed before the nozzle after homing is by design, to move into zone.
