All it takes is one typo. 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 … So is the autolevel useful or not ? Long Beep on Boot. The offset is not stored in EEPROM AFAIK and there's no z-offset in this Marlin version. The High Resolution Mesh capabilities are impressive. 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. i'll be around, but not near my delta. @Roxy-3D Most of those probed points seem fine to me. Just in case. I did a pull request today.....sorry it took so long I had to learn how to use git. Configurations, please It would be prudent to do an M48 where ever on the bed you home the Z-Axis. But let me help you understand why I'm being slow accepting the ideas. One 'bad' point, especially, if it it is off a bunch, will pull things much more than it 'should' in that direction. I recently setup auto bed leveling which technically is working when I run G29 but I cannot get the nozzle close enough to get a successful print. 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). 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 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 ? I'll get all flavors of Auto Bed Leveling working for all types of printers. is it worth that i bothered config it ? :). I put 5mm on marlin on z offset to be sure, and same thing, 2mm. I am still pretty new to this and still used my original config files. 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. Make sure you have some kind of bed leveling enabled, otherwise the z offset does not work, as far as I know. I've also tuned the z-offset … Changing the machine name would have no affect over it reading from EEPROM or not. The P parameter only changes the Z offset for the z-probe.. 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 … 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. 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. 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. Once you have made the offset settings, don’t forget to save the value in memory. requested in the Issue template) and drop them into your next reply. I cranked it down all the way to -10 while printing a test print. 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 changed it to 11mm and the nozzle were still at 2 mm above the bed. to your account. Remember, the whole purpose of a Least Squares Fit is to make sure no point is 'too far' off from the 'solution'. While the printer is printing the skirt, you will adjust the Z Probe Offset. 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. #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 No. Normally after the G29 command completes, the nozzle with drop to the zero position, hesitate and then go down the Z offset distance. 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. Dunno if thinkyhead still has this printer and might be able to say its just me alone having this issue anyway. see. But, every time when I try to input this … It turned out that creality made a mistake when designing the menu. If you don't mind, please post a log. Please ZIP up your Configuration.h and Configuration_adv.h files (as The Z offset can be overridden with M851 Z … For X and Y … @fleek just tested it ... sorry had gone to work. ... as to the tools required and how the marlin firmware interacts with it. is there a way to not manually reconfigure the configs.h files ? Active 1 year, 8 months ago. 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. Z has to be accurate and has to be adjusted quite accurately. However, at “user level” in the LCD menus, we refer to the first extruder as E1, the second as E2, etc. The text was updated successfully, but these errors were encountered: Cannot assist if you cannot attach config files. You coul try to remove or replace https://github.com/MarlinFirmware/Marlin/blob/RCBugFix/Marlin/Marlin_main.cpp#L3240-L3243. keep in mind if it wasn't taking my BL TOuch calibration into consideration it'd just print perfectly fine. When you power up it displays the settings that are being used so you can easily verify if things are changing or not. I measured the offset to .5mm by placing the nozzle on the bed and going up … Looks like we have to wait a while longer for this to be released. I do a g28 then g29 g1x100y100 f5000 then manually set Z tll it just barely touches paper. That's pretty much always how I adjust mine. There's one outlier, which triggers the probe earlier, at 2.3, a half-millimeter higher than the other probes. Printer is a stock Anet A8 with a fresh copy of marlin 1.1.9 installed. Take the current Z value and negate it. My probe offset is about -2.22. 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. The Z offset should be specified as exactly as possible using a decimal value. is at the bottom and setting z offset to 0.3 would mean that after.

I was using 2.0.5.3 as a base. I even cranked it all the way down to -6.72 without a bed crash. Have a question about this project? I am trying to resolve this together with #18800, so it will take some time. setting z-offset works and you can save it but the live tuning adjustments dont. see here. M500 – Saves our offset we have just input to the printers EEPROM and you are finished setting your Z offset, the offset can also be accessed by the M428 sets home offsets so the current position aligns to the native home position. I know this is confusing and it is something that ok going to change slightly in my next version.. Make sure you that you reset the eeprom, save it, then powercycle first. This turned out to be a simple menu programming error of the menu. This one adjusts Z based on the homing position: 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. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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. i have found drop sagment, replaced it and add one to 5, no changement. Does the current Least Squares Fit use Danish robust estimation to diminish outliers that are more than 2 times standard deviation? If you find that your nozzle is still too high, even if you don't use G29, then perhaps try reducing your Z_HOME_POS (and/or Z_MANUAL_HOME_POS) by 2. Dear @tyssoon I have mine working now the way its supposed to be. my log of m111/g29/g28 and print then reset. I have the same issue with my Marlin printers. 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 … My code is now based on 2.0.6 (84b96d3) and the Z probe offset no longer appears to work. In general, on deltabots the probe should be connected to the unused Z-Min endstop pin (if there is one).
