I mean it was the ender 3 v2 using DWIN. @brainscan 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. Posted by BrokePilot . By clicking “Sign up for GitHub”, you agree to our terms of service and 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. It is the offset that you define with command M851 e.g. Already on GitHub? @Roxy-3D Yeah - the units here are in mm - the marlin limitation is +/- 10mm by default, and adjustable in 0.01mm increments. I have the z-offset plugin installed and am running cura 3.4.1 under Ubuntu 18. (Marlin 2.0 includes an option to show the first extruder as E0.) Mainly all similar to this below: By clicking “Sign up for GitHub”, you agree to our terms of service and I don't have numbers yet. I put 5mm on marlin on z offset to be sure, and same thing, 2mm. Please ZIP up your Configuration.h and Configuration_adv.h files (as No it doesn't throw out any outliers. I mean it was the ender 3 v2 using DWIN and I was nice enough to provide a video. Would of prefered to level bed manually but was not given that option..is the dual the only version without the calibrate option? Question. You signed in with another tab or window. Changing the home offsets will not invalidate bed leveling or other saved data. 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. Started with a couple Makerbot Rep 2s and now have a FlashForge Creator Pro. The current position is adjusted to align to the new home offset values. You coul try to remove or replace https://github.com/MarlinFirmware/Marlin/blob/RCBugFix/Marlin/Marlin_main.cpp#L3240-L3243. Sign in I hope I won't need to resort to that 'fix'. It would be prudent to do an M48 where ever on the bed you home the Z-Axis. 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'd recommend re-downloading RCBugFix from today (because there was a glaring bug applying z offset twice) and re-testing. All it takes is one typo. it's working everything expect it's printing above the bed. The sensor is meant to detect the bed before the nozzle touches the bed. Move Z down slowly until the probe triggers. I understand what you are saying. I needed to swap my wires around for this also (grey to white spot). privacy statement. 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. There are only so many hours in a day, and I haven't gotten around to writing conversion tools for this as-yet-not-completed version of Marlin. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). 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. I've had to resort to repeatedly modify->compile->upload to fine tune my offset. I some what expect to see 'outliers' when I start probing the the edge of the Print Radius. Especially the locations where there is any 'outlier' point. Z has to be accurate and has to be adjusted quite accurately. Pointing to your suggestion here seems sane: I was using 2.0.5.3 as a base. I've had to resort to repeatedly modify->compile->upload to fine tune my offset. Hey everyone! Also to verify movement I both watched the motor and light laid my finger on the spindle to detect even the slightest movement. It looks like there are configs attached now and someone is already trying to help, so hopefully something can be figured out. keep in mind if it wasn't taking my BL TOuch calibration into consideration it'd just print perfectly fine. If EEPROM_SETTINGS is enabled, the home offsets are saved with M500, loaded with M501, and reset with M502. Once you have made the offset settings, don’t forget to save the value in memory. @thinkyhead #define MIN_STEPS_PER_SEGMENT 6 This is the vanilla version of Marlin Firmware 2.x pre-configured for Creality Ender 3 printers with original or generic BL Touch sensors. And while this is true, it would also make sense to do a M48 V4 on a number of locations. I measured the offset to .5mm by placing the nozzle on the bed and going up … i will postthe results soon. I know this is confusing and it is something that ok going to change slightly in my next version.. Both will give different results. Mon Sep 19, 2016 8:46 pm . The easiest way to get the Z offset value is to: Home the Z axis. Enable DEBUG_LEVELING_FEATURE and issue the command M111 S255 before doing a G28 and G29. 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 i'll pause the tuning for some time, seeya in a week or two. I suspect this is a configuration issue. Rich Has this been added to the nightly builds yet? 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. This value you can set also via display (Marlin): Menu→Control→ Motion→Z-Offset. I need some suggestions for a z offset issue. Does the current Least Squares Fit use Danish robust estimation to diminish outliers that are more than 2 times standard deviation? Hopefully it will be added to the next nightly build. #define Z_PROBE_OFFSET_FROM_EXTRUDER 0. Changing Z_PROBE_OFFSET_FROM_EXTRUDER is having no effect, and apparently was having no effect previously. Keep tuning. My probe offset is about -2.22. Marlin turns off the BEEPER pin as soon as it possibly can. 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. Yes it indicates, but it ignores it. New Marlin 2.x Versions # define NOZZLE_TO_PROBE_OFFSET { 10, 10, 0 } In this setting the offsets are X, Y, Z. I am still pretty new to this and still used my original config files. The Z offset should be specified as exactly as possible using a decimal value. Have a question about this project? privacy statement. 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. Expected behavior: when you adjust the z-offset while printing the z-offset should change. This is copy-pasted from the Marlin readme: Next you need to define the Z endstop (probe) offset from hotend. Download files and build them with your 3D printer, laser cutter, or CNC. If yes, can you be more specific in the way you did please ? At the moment I am using the EZABL's version of Marlin on a Bigtree tech e3 mini v2 anyone any ideas The High Resolution Mesh is the Cat's Meow for 3D-Printer Bed Leveling. If it works I will push the fix to the main repo. Scroll down and click one of the Macro buttons. However, at “user level” in the LCD menus, we refer to the first extruder as E1, the second as E2, etc. 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. Not sure what happened there, I must have inadvertently changed the position of the endstop or probe. but u were right, i tuned z home pos to 685 and now it's okay i can print. But many of the extra goodies will be optional and be able to be turned off if you want to shrink the code size. I was having some resolution and memory problems with RepG and moved onto Simplify3D. Please open a new issue for related bugs. I have (I hope) attached my Configation.h and Configuration_Adv.h. 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. // Does not require M206 and indeed required M206 to be clear. M851 Z-1.85 that determines the To have this fix, i just need to download and compile bugfix branch and flash the printer? I also just found that there was an option that lets you change the z-offset with the babysteps that I might turn on. I was at 13.4mm on z offset on marlin. 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. 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. This turned out to be a simple menu programming error of the menu. ^^. using current firmware. I have configured #define NOZZLE_TO_PROBE_OFFSET { 0, -41, -2.22}. where is the place in marlin where i can change that please. Nothing in the title or description indicated this was an Ender 3 V2 or that it was DWIN. [Bug] Ender 3V2 z-offset tuning not working. Configuring Marlin Bed Dimensions. Joined: Aug 5, 2016 Messages: 88 Likes Received: 7. Marlin Zprobe offset not working. Tuck into this detailed guide of setting up Marlin for auto bed leveling to make sure that that shiny new probe actually works! This is a hardware issue due to the connected beeper pin being HIGH when the board is first powered. i go on vacation tommrow guys. Higher Z-Offsets are 1, 1.1 and 1.2. I think I am seeing a similar issue. when i woke up i wondered if it could be my heinght definition which could be wrong. It was a simple mistake in programming the menu. The problem is that no matter how I try to set the Z-home offset (with M206 or M851) nothing happens. Now turn off the software endstop temporarily (with M211 S0) to enable lowering the nozzle further down to the bed. ... // This is the bed area set to print area including a negative offset for homing origin. But, every time when I try to input this … M500 then m502, no results. i have to sand a bit my effector to be sure that i can print. Sorry if it hasn't helped but did you do m500 m502 or m502 m500? One 'bad' point, especially, if it it is off a bunch, will pull things much more than it 'should' in that direction. Configurations, please 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. I don't have the code up and running yet on Delta's. i'll be around, but not near my delta. Let's make sure your probe 'repeats' well enough that it isn't causing problems. At which place in the delta levelling is LSF in use? 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.) Make sure you that you reset the eeprom, save it, then powercycle first. Tuning a delta is tricky, but when out of tune, the height at center and at the edges will differ. 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. m500+m502 have changed nothing, so i think this is not an eeprom problem. is at the bottom and setting z offset to 0.3 would mean that after. I even cranked it all the way down to -6.72 without a bed crash. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. If it works, then let it actually auto-home and then set your z offset using the menus and a piece of paper and finally do a bed leveling and save the settings! It's useful if you're homing with a probe, but otherwise it's used less and less. So is the autolevel useful or not ? tell me what you need to help me guys ! 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. thanks for your help. View the current offsets with M503. I put 5mm on marlin on z offset to be sure, and same thing, 2mm. 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. 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. nope, omron switch which i manually turn up and down. https://github.com/thinkyhead/Marlin/tree/rc_fix_leveling_maths, And this one adjusts Z based on the final probe position: Raise Z and deploy the probe. 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). 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. #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 I am not rejecting those thoughts. This one adjusts Z based on the homing position: The offset is not stored in EEPROM AFAIK and there's no z-offset in this Marlin version. i think with DWIN_SET? Just in case. When you power up it displays the settings that are being used so you can easily verify if things are changing or not. Baby stepping via commands works so I know it does that. https://www.youtube.com/watch?v=6C7-YI-uQ9s. These offsets specify the distance from the tip of the nozzle to the probe — or more precisely, to the point at which the probe triggers. But it will be very soon in the UBL branch. Check the Z position on the printer screen, and subtract another 0.1 from this value to account for the thickness of the paper. @cosmoderp 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.) Especially in the case of Deltas, I think we expect there to be 'outliers' because of the cup and bowl shape of the bed. i have found drop sagment, replaced it and add one to 5, no changement. You can not only change the Z offset in the slicer or in the configuration of Marlin, but also with G-code commands. 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. Dear @tyssoon Z offset not being saved (marlin 2.0) So still having trouble trying to get my bltouch going. I have been working on a menu and hope to push out a fix soon. 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. On machines that use Z-min for an endstop, the Z-Max pin is recommended next, so … So no more leveling nor fiddling with the Z offset! The "paper drag" method is perfect for determining the correct Z level. I do a g28 then g29 g1x100y100 f5000 then manually set Z tll it just barely touches paper. Thingiverse is a universe of things. do i have to bother ? Example: The feature is available in the newest Marlin firmware. You signed in with another tab or window. Note the z again. ( 5.2 => -5.2) Set with M851 Z-5.2 and #define Z_PROBE_OFFSET_FROM_EXTRUDER -5.2. M428 sets home offsets so the current position aligns to the native home position. 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. For X and Y … i have a bowl bed, i dont understand how since it's a borosilicate which cost me an arm but i do. I calculated the offset (-2.98). We’ll occasionally send you account related emails. 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. Hi all, I have recently setup my Z probe and got G29 working correctly, It compensates for an unlevel bed (I can see Z changing) however, I cannot seem to get the Z probe offset set correctly. Marlin just release v1.1.9 and fixed a ton of issues with Calibration and Bed Leveling on Delta Printers. (not retracting just printing) by a slight amount. 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). At witch place in the delta levelling is LSF in use? I have no idea why this worked but it did. As you know, it isn't currently used for Delta's. 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. My z probe offset for bltouch is -2.7, after homing Z sits at 17.7, but when it prints it prints in the correct place. requested in the Issue template) and drop them into your next reply. 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. it prints up in the air. Normally after the G29 command completes, the nozzle with drop to the zero position, hesitate and then go down the Z offset distance. 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. If they do not match then the kit will not work correctly. Specifying Z offset in Marlin firmware. The X and Y offsets are specified as integers. 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. 2 $\begingroup$ I need to set a Z offset for the Flying bear P902. is it worth that i bothered config it ? The High Resolution Mesh capabilities are impressive. 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. Actual behavior: it does not respond to any changes. so the rcbugfix is still bugged ? 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. Slice the STL file with your desired settings and print it on your printer. But let me help you understand why I'm being slow accepting the ideas. 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 … 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: Printer is a stock Anet A8 with a fresh copy of marlin 1.1.9 installed. Successfully merging a pull request may close this issue. Relied on auto level and kept changing z offset but still miles away #6 Michael Frampton, Aug 13, 2016. E.g. We’ll occasionally send you account related emails. M502 M500. 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 have a diy delta and when i launch a print, after a G28 and G29, the nozzle is 2 mm off the print surface. my attempt was: const int MIN_STEPS_PER_SEGMENT = 6; not so far ! The honest truth is, if you have the High Resolution Mesh, you don't need anything else. I'm beginning to wonder, myself. Does not seem to have fixed it for me. lwaynej perhaps you should start a new bug report by the looks of your issue. 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. im almost sure that EEPROM is on, if i undertood well what it is. 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.
