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. Michael Frampton Well-Known Member. level, set the offset to negative, issuing z0 command will move the z. axis upwards. Videos are useful, but it's not reasonable to expect people to go watch videos when quickly screening issues to see if they can help. For X and Y … Raise Z and deploy the probe. I needed to swap my wires around for this also (grey to white spot). Marlin provides reasonable defaults, but they will not apply to every situation. M206 Z-0.2 reduces the apparent length of the Z axis by 0.2mm. I'm beginning to wonder, myself. Successfully merging a pull request may close this issue. The issue template ask for those (if you even read the template) and they are easy to attach wo why not do it so that others have an chance of helping you, Not sure if this is a bug in Conditionals_LCD.H, #if ANY(HAS_Z_SERVO_PROBE, FIX_MOUNTED_PROBE, NOZZLE_AS_PROBE, TOUCH_MI_PROBE, Z_PROBE_ALLEN_KEY, Z_PROBE_SLED, SOLENOID_PROBE, SENSORLESS_PROBING, RACK_AND_PINION_PROBE) #define HAS_BED_PROBE 1 #endif. @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. using current firmware. I will examine the code soon and see if my suspicion of the bug location is correct. @CRCinAU for configurations since its he keeps it private. 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 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. However, at “user level” in the LCD menus, we refer to the first extruder as E1, the second as E2, etc. 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 calculated the offset (-2.98). thanks for your help. @cosmoderp The standard configuration file from Marlin distribution was carefully reviewed to include the latest Ender 3 specific settings from … and it should be around 4ish mm when bed crash. 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. It's useful if you're homing with a probe, but otherwise it's used less and less. 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 … The z offset … I have configured #define NOZZLE_TO_PROBE_OFFSET { 0, -41, -2.22}. I don't want to throw out data. Active 1 year, 8 months ago. 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. Configurations, please 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. I need some suggestions for a z offset issue. You signed in with another tab or window. Dunno if thinkyhead still has this printer and might be able to say its just me alone having this issue anyway. At the moment I am using the EZABL's version of Marlin on a Bigtree tech e3 mini v2 anyone any ideas The "paper drag" method is perfect for determining the correct Z level. The X and Y offsets are specified as integers. Hey everyone! I was using 2.0.5.3 as a base. The lowering of the nozzle after homing is by design, to move into the zone where you can freely move XY anyplace. This is the vanilla version of Marlin Firmware 2.x pre-configured for Creality Ender 3 printers with original or generic BL Touch sensors. If you can’t find it, you can alternatively run the command M500 (Save settings). https://github.com/thinkyhead/Marlin/tree/rc_fix_leveling_maths, And this one adjusts Z based on the final probe position: Installation went without a hitch. Check your Z endstop trigger: EZABL – Z Not Showing “TRIGGERED” M119 Test I do a g28 then g29 g1x100y100 f5000 then manually set Z tll it just barely touches paper. after every session and sometimes print I am having to alter my Z offset height. privacy statement. Normally after the G29 command completes, the nozzle with drop to the zero position, hesitate and then go down the Z offset distance. To have this fix, i just need to download and compile bugfix branch and flash the printer? The easiest way to get the Z offset value is to: Home the Z axis. Ask Question Asked 1 year, 8 months ago. Hopefully it will be added to the next nightly build. I have (I hope) attached my Configation.h and Configuration_Adv.h. 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. so the rcbugfix is still bugged ? View the current offsets with M503. I understand what you are saying. Just in case. ^^. Marlin just release v1.1.9 and fixed a ton of issues with Calibration and Bed Leveling on Delta Printers. The offset is not stored in EEPROM AFAIK and there's no z-offset in this Marlin version. When I try to "set home offset" on the printer I get "Error: too far from refrence point". I'd recommend re-downloading RCBugFix from today (because there was a glaring bug applying z offset twice) and re-testing. cosmoderp changed the title z-offset tuning not working [Bug] Ender 3V2 z-offset tuning not working Jul 28, 2020. I don't have the code up and running yet on Delta's. 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. Nothing in the title or description indicated this was an Ender 3 V2 or that it was DWIN. So, for example to change the z offset for the probe to -7.5 you would use M666 P-7.5. Both will give different results. my log of m111/g29/g28 and print then reset. @Roxy-3D 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. Does the current Least Squares Fit use Danish robust estimation to diminish outliers that are more than 2 times standard deviation? Especially in the case of Deltas, I think we expect there to be 'outliers' because of the cup and bowl shape of the bed. But if that is what it takes to get the Grid Based running well, you can bet it will end up in the code! Is this an 'inductive' probe? neither, anyway thanks to trying to help, even it doesnt :). Configuring Marlin Bed Dimensions. @tyssoon If you do a print with just G28 and no G29 is your nozzle still starting 2mm too far above the print surface? I even cranked it all the way down to -6.72 without a bed crash. The value for X and Y can be quite coarse. M428 sets home offsets so the current position aligns to the native home position. https://www.youtube.com/watch?v=6C7-YI-uQ9s. 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. i changed it to 11mm and the nozzle were still at 2 mm above the bed. 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. 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. homed the nozzle is far from bed, but issuing command to z0 is not. This one adjusts Z based on the homing position: see. 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. On machines that use Z-min for an endstop, the Z-Max pin is recommended next, so … Question. All it takes is one typo. Forum List Message List New ... 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. From RepRap. but u were right, i tuned z home pos to 685 and now it's okay i can print. But it will be very soon in the UBL branch. 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. Specifying Z offset in Marlin firmware. If it crashes in to the bed, try to do Note #2 above. is there a way to not manually reconfigure the configs.h files ? @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. 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). @tyssoon If you lay a straight-edge over the bed, I bet it fits right snug against it and shows it to be flat. I measured the offset to .5mm by placing the nozzle on the bed and going up … Tuck into this detailed guide of setting up Marlin for auto bed leveling to make sure that that shiny new probe actually works! @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. 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. where is the place in marlin where i can change that please. I put 5mm on marlin on z offset to be sure, and same thing, 2mm. tell me what you need to help me guys ! 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! if there are changes to the main config file though and I was meant to simply make all the needed changes myself be advise. Take the current Z value and negate it. Looks like we have to wait a while longer for this to be released. I some what expect to see 'outliers' when I start probing the the edge of the Print Radius. The Z offset should be specified as exactly as possible using a decimal value. Keep tuning. Sign in 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. 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 When you power up it displays the settings that are being used so you can easily verify if things are changing or not. 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 I cranked it down all the way to -10 while printing a test print. The High Resolution Mesh capabilities are impressive. I mean it was the ender 3 v2 using DWIN. 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. Yes. Hi, can i download last marlin or one of yours, replace the configuration.h and configurationadv.h by mines without problem ? 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. If you have a delta its much more likely you calibration is off, then the bed is not flat. 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. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). i have to sand a bit my effector to be sure that i can print. z-offset does not change live when using the tuning menu. :D. i managed to correct the rest of the errors alone like a big boy. 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). This issue has been automatically locked since there has not been any recent activity after it was closed. i changed it to 11mm and the nozzle were still at 2 mm above the bed. Z homing was not working at all until I uncommented "USE_PROBE_FOR_Z_HOMING". Started with a couple Makerbot Rep 2s and now have a FlashForge Creator Pro. M851 Z-1.85 that determines the Long Beep on Boot. The current position is adjusted to align to the new home offset values. Actual behavior: it does not respond to any changes. privacy statement. The home offset is persistent — added to the current position until changed. i will test what happen with a G29 before. 2 $\begingroup$ I need to set a Z offset for the Flying bear P902. Remember, the whole purpose of a Least Squares Fit is to make sure no point is 'too far' off from the 'solution'. i have found drop sagment, replaced it and add one to 5, no changement. Slice the STL file with your desired settings and print it on your printer. Viewed 12k times 4. I suspect this is a configuration issue. I know this is confusing and it is something that ok going to change slightly in my next version.. Now with Cura, it drops to Z=0 but never drops the offset amount before starting to print. 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. If you don't mind, please post a log. [Bug] Ender 3V2 z-offset tuning not working. I configured Marlin 1.1.3 for auto-leveling with a fix mounted sensor connected to the Z end-stop pin. Thingiverse is a universe of things. Bug Description z-offset does not change live when using the tuning menu. You coul try to remove or replace https://github.com/MarlinFirmware/Marlin/blob/RCBugFix/Marlin/Marlin_main.cpp#L3240-L3243. This value you can set also via display (Marlin): Menu→Control→ Motion→Z-Offset. I put 5mm on marlin on z offset to be sure, and same thing, 2mm. Already on GitHub? This is a hardware issue due to the connected beeper pin being HIGH when the board is first powered. :). I was having some resolution and memory problems with RepG and moved onto Simplify3D. If you are not using Mesh Bed Leveling, just set it to 0.000. Yeah - the units here are in mm - the marlin limitation is +/- 10mm by default, and adjustable in 0.01mm increments. swapped the config.h and obtained that in the rcbugfix. The Z probe offset is being ignored. I also just found that there was an option that lets you change the z-offset with the babysteps that I might turn on. And I'm still going to do that. Baby stepping via commands works so I know it does that. do i have to bother ? Check the Z position on the printer screen, and subtract another 0.1 from this value to account for the thickness of the paper. The sensor is meant to detect the bed before the nozzle touches the bed. 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. i'll be around, but not near my delta. i.e., 680 instead of 682. i dont understand what the z offset is for so ^^. I was at 13.4mm on z offset on marlin. 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. Use that bat file to open the project and flash your image.Test the BLTouch with your finger again. However, in the version of marlin I use, I had to patch it so that the M206 command behaved the way we want with software endstops and Z homing to MAX. We’ll occasionally send you account related emails. I did a pull request today.....sorry it took so long I had to learn how to use git. I am still pretty new to this and still used my original config files. Just make sure that the G29 command comes after the very last G28 command in the script. 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. Yes it indicates, but it ignores it. 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. Please note that starting scripts may vary from one printer to another. Printer is a stock Anet A8 with a fresh copy of marlin 1.1.9 installed. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. it prints up in the air. The only thing can go is to have the physical nozzle below the bed. the issue I have is the z offset not changing anything. possible. No it doesn't throw out any outliers. (not retracting just printing) by a slight amount. Mon Sep 19, 2016 8:46 pm . Have a question about this project? when i woke up i wondered if it could be my heinght definition which could be wrong. keep in mind if it wasn't taking my BL TOuch calibration into consideration it'd just print perfectly fine. 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. Post the log output here so we can see what's going on. I don't have numbers yet. I have mine working now the way its supposed to be. Rich By clicking “Sign up for GitHub”, you agree to our terms of service and Changing the machine name would have no affect over it reading from EEPROM or not. 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. I'll get all flavors of Auto Bed Leveling working for all types of printers. You can not only change the Z offset in the slicer or in the configuration of Marlin, but also with G-code commands. Bltouch not working properly. 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. I can only assume that the HAS_BED_PROBE case is used for setting an offset with a probe attached, but it will fall back to using BABYSTEPPING if we don't have a probe configured in... @cosmoderp can you pull from my repo fleek/Marlin:bugfix-2.0.x and test if the fix works for you.
