marlin z raise after homing

I've run into this a few times over the last week trying to double- and triple-verify the bed-leveling bug. Have a question about this project? That means the distance between the nozzle and the bed – the Z offset – needs to be just right.. With the Ender 3 and the Ender 3 Pro, there are a few important reasons to change the Z offset: to ensure the bed can be properly leveled, to print on top of another object, and to print more complicated models. The text was updated successfully, but these errors were encountered: Edited: Seems github ate the contents. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. If homing is needed the LCD will blink the X Y Z indicators. [BUG] Baby-stepping screen not accepting user change, fixes #19579, Z_AFTER_HOMING ignored with no probe. Expected behavior: [What you expect to happen] It compiles but I am not in a position to test on a actual machine atm. This effectively shifts the coordinate space in the negative direction. We all work independently mostly from home (but some from their work) and we are planet wide. Configs, descriptions, even a video. Not even LCD levelling. # define Z_RAISE_BETWEEN_PROBINGS 3 // How much the extruder will be raised … Hi guys! I see the Z raise only after G28XY finishes. I am just keeping it as a backup, but now I think if I needed it I might just buy something anyway. Right now, G28 first lifts Z by 10mm, homes X and Y, and then tries to home Z, but since there is no endstop it would push the spindle into the wasteboard and probably rip itself apart. Nevermind my previous post. I don't have access to this type of controller board at all. With any 3D print, getting a solid first layer sets the scene for the rest of the job. Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. You signed in with another tab or window. Remember most of us are volunteers, working in our own time. Uncomment Z_SAFE_HOMING. In any event, it still says on the bed and does not raise Z. I also have two other printers that DO have probes and levelling, and those do raise the Z axis after homing. Also, re-reading the bug description I said "with or without safe homing", but I have had safe_homing defined for a long time. See examples below. Actual behavior: [What actually happens] Based on bugfix branch. This is good for machines whose beds fall when Z is powered off. When I do a G28 to test the print head goes as expected to the front left of the print bed. I'll confirm it. Carefully give this this new probe.h a try probe.zip Notes. I've already saved the mesh and have the mesh loaded during prints after G28. Mesh Bed Leveling (MBL) allows interactively measuring a Z height mesh without a bed probe. To see how slow my Z axis is moving check #define Z_SAFE_HOMING. If we have the sensor on a servo we need some space. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. MBL uses the mesh to compensate for variations in height across the bed. Homing and Bed Leveling [#3707] : Fix curved movements in G29 for Delta [#3775] : Report current position to host after G29 [#3782] : Require homing of Z before G29 bed leveling [#3798] : Allow using probe indices (I and J) with M421 Set Probe Point [#3942] : Fix servo probe raise in G28 and other non-leveling contexts Naturally you'll need to have your min endstops wired up or you'll have a machine crash when it tries looking for said min endstop. I created a PR so it will be fixed for all, moving forward. Z_RAISE_BEFORE_HOMING only after homing XY? parent 3b4c89e4 I moved the function move_z_after_homing() out of the #ifdef block. on Repetier-Host. 2) Limits after homing Then I had to change the settings of the travel limits after homing. Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. #ifdef Z_SAFE_HOMING This behavior has been around with several versions of Marlin 2.0, but lately it's 2.0.6.1, 2.0.7, and bugfix-2.0.x updated a few days ago. I will go through my Marlin config to make sure I didn't miss anything, but I think this is the case. Successfully merging a pull request may close this issue. ... #define Z_RAISE_BEFORE_HOMING 23 // (in mm) Raise Z before homing (G28) for Probe Clearance. Already on GitHub? Description. Marlin, BLTouch, z endstop as a backup? Since I’m homing to Z-max when G28 is executed by marlin it will home Z first (moving to the endstop, and setting Z to Z_MAX_POS (0 in my case). Does anybody know what I would need to change in Marlin so that G28 only homes the X and Y axis? That certainly looks like what the code is doing, but I haven't tested it. Dang it! It would be nice (in spite of protestations against making this available) if it was also available when not using a probe, and if it was applied when homing X and Y (but not Z when there's a regular endstop). That worked, Thank you. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Denn vor knapp 3 Stunden wurde ein „Big Update“ veröffentlicht und Marlin steht ab sofort in Version 2.0.6 zum Download bereit. A quick check of the config revealed that it wasn't enabled on this machine, so enabling and re-flashing and all is good. As noted in #1736 it looks like Z_RAISE_BEFORE_HOMING occurs just when homing Z and only after homing X and Y. I had a little scare when the first time I tried it, it didn't lift. If stepper drivers time out, X and Y homing will be required again. By now, the home offset should be ready for the first 3d print test, all we need to do now is test the offset setting, like in step 5, just to confirm we are ready to go. Doing both after a HOME is a BUG. It works EXCEPT the mosfets for fan0 and fan1 blew, but fan2 still works. Since my proximity sensor is placed right of the extruder, see the attached picture, I had to limit the X_MAX_POS to 130. #1748 has the Z axis raise before homing X and Y, but still homes Z last. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I don't think normal homing does the multi-probe, but I'm not sure about that. I want to use the BLtouch for z homing as well as bed leveling - so far this looks like it will work fine. Have a question about this project? Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . My printer is a Monoprice Mini V1 with a lot of mods, including a 32-bit controller and TMC2209 drivers. I used the latest Marlin 1.1.x bug fix edition (1.1.9) and now everything is working correctly except X and Y homing, the machine throws the error: printer halted. I notice this at x and y axis but they definitely are not as slow as the z axis. Homing is required before G29, M48, and some other procedures.. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. // Be sure you have this distance over your Z_MAX_POS in case # define Z_RAISE_BEFORE_PROBING 10 // How much the extruder will be raised before traveling to the first probing point. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. but my Z is at the bottom in the first time, so the Z can not go down any more. Successfully merging a pull request may close this issue. Go to step 7 to test the new settings. I will just make sure on my Ender 5 Plus too. Expected behavior: [What you expect to happen] Expect the printer to home, and then raise Z_AFTER_HOMING distance. There is no probe, and no levelling of any kind defined in Marlin. I am using the latest version of Marlin and it gave me nothing but issues, printer wouldn't move or home at all. G28 disables bed leveling. When homing, with or without safe homing, the Z axis completes the double "probe", but the nozzle stays ON the bed. Guten Morgen in die große weite Welt und diesen Tag möchten wir mit einem Artikel rund um die neue Marlin Software starten. After homing the 3d printer again, the Z axis will be updated, and the -2.5 position will become the new zero position. Use M206 to apply a persistent offset to the native home position and coordinate space. If this is the case, then I will move the Z lift in front of the X and Y homing, and it will be applied only in the appropriate cases. Anyway, I have an SKR Pro V1.1 laying around not doing anything. privacy statement. You signed in with another tab or window. I have posted my marlin code for my autobed leveling below. Just traded one for the other. Please open a new issue for related bugs. For this topic, I have two problems with my 3d printer. And reopened. Printer homes but does not... qwewer0 - Thank you for copying what you could get. when I update Marlin to v1.1, I found when I execute homing, the Z will raise(go down) for a little distance before XY homing. By that logic you should implement Homing backoff after probing. This issue has been automatically locked since there has not been any recent activity after it was closed. I’m using dual endstops on the X and Y axis, and no endstop on the Z axis. You will need to make sure software endstops are DISABLED for Z after adding the probe. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled // - If stepper drivers timeout, it will need X and Y homing again before Z homing // - Position the probe in a defined XY point before Z Homing when homing all axis (G28) // - Block Z homing only when the probe is outside bed area. For machines with both Z max and min endstops, there is no caveat. Press the controller button to save the Z value and move … to your account. Well If you want to send it. Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. I'll try it out on one of my other printers "just to make sure". Closing. Expect the printer to home, and then raise Z_AFTER_HOMING distance. idk) will let you print without homing Z as long as it knows where zero is. (kill() called! I'll try again tomorrow. I'll close this as soon as I double confirm with my Ender 5 Plus (SKR Pro controller/TMC2209's and EZABL probe if that matters) tomorrow. Unzip and put in Marlin/Marlin/src/module/probe.h // Travel limits after homing #define X_MAX_POS 130 #define X_MIN_POS 0 #define Y_MAX_POS 110 #define Y_MIN_POS 0 #define Z_MAX_POS 100 This will let you adjust the Z to a negative number for your offset. The attached configs are the last of maybe 5 attempts to get this working. #define Z_AFTER_HOMING 10 appears to be ignored. Actual behavior: [What actually happens] Z Safe Homing prevents Z from homing when the probe (or nozzle) is outside bed area by moving to a defined XY point (by default, the middle of the bed) before Z Homing when homing all axes with G28. Without this, you may accidentally miss the bed when homing Z. Contact me Directly we can work out the details. This prevents your Z homing from occurring without prior X and Y homing. Weâll occasionally send you account related emails. YAY. The text was updated successfully, but these errors were encountered: For 'save homing' is a requirement that x & y are homed. Copied from Discord, not everything, but better than nothing: When homing, with or without safe homing, the Z axis completes the double "probe", but the nozzle stays ON the bed. Already on GitHub? I don't know what happened, but I had everything in it. Weâll occasionally send you account related emails. 1) My Z axis speed is very slow. So, are you confirming that Z_RAISE_BEFORE_HOMING is not being applied before homing X or Y? Unfortunately no. When I dial the Bed Z value, when the printing starts, to bring the nozzle closer to the bed, it doesn't immediately reflect on the nozzle (like the babystep does). With this option enabled, Z won't ever be raised until after `G28` has been completed, and it won't raise if Z becomes unknown. I just tried this on my CR-10S which DOES have a probe and levelling, and now it does not raise Z after homing. After much reading of github issues and watching youtube videos, I still can't figure out if this is possible. Am I misunderstanding the purpose of this setting, or should it be applied first, to raise the Z axis, before homing X and Y in G28? Marlin.zip. When homing z the switch has to be unswitched! Now the only time the Z motors make noise/vibrate is right after the homing is complete and they briefly move up when the nozzle begins to heat, as well as right after the heating is done and the nozzle dips down to begin the print.
