marlin z raise after homing

Sign up for a free GitHub account to open an issue and contact its maintainers and the community. For machines with both Z max and min endstops, there is no caveat. I notice this at x and y axis but they definitely are not as slow as the z axis. Steps to Reproduce. And reopened. 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. // - If stepper drivers time out, it will need X and Y homing again before Z homing. Just home the machine. By that logic you should implement Homing backoff after probing. Since my proximity sensor is placed right of the extruder, see the attached picture, I had to limit the X_MAX_POS to 130. Z_RAISE_BEFORE_HOMING only after homing XY? After homing the 3d printer again, the Z axis will be updated, and the -2.5 position will become the new zero position. privacy statement. 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. Carefully give this this new probe.h a try probe.zip We all work independently mostly from home (but some from their work) and we are planet wide. I've already saved the mesh and have the mesh loaded during prints after G28. 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? It compiles but I am not in a position to test on a actual machine atm. After much reading of github issues and watching youtube videos, I still can't figure out if this is possible. Hi guys! idk) will let you print without homing Z as long as it knows where zero is. [BUG] Baby-stepping screen not accepting user change, fixes #19579, Z_AFTER_HOMING ignored with no probe. I'll try again tomorrow. // - Prevent Z homing when the Z probe is outside bed area. This will let you adjust the Z to a negative number for your offset. By clicking “Sign up for GitHub”, you agree to our terms of service and I see the Z raise only after G28XY finishes. You will need to make sure software endstops are DISABLED for Z after adding the probe. // 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. As noted in #1736 it looks like Z_RAISE_BEFORE_HOMING occurs just when homing Z and only after homing X and Y. Confirm XY position before Z Safe Homing; For G28 Z with Safe Homing, raise before move to XY; Fix SD_FINISHED_RELEASECOMMAND bug; Fix extra call to unskew() Limited backlash editing for Core kinematics; Support up to 8 Trinamic E drivers; Apply HOME_BEFORE_FILAMENT_CHANGE if any axis is unknown; Consider HOME_AFTER_DEACTIVATE for Z safe homing That certainly looks like what the code is doing, but I haven't tested it. I'll try it out on one of my other printers "just to make sure". If stepper drivers time out, X and Y homing will be required again. This effectively shifts the coordinate space in the negative direction. Use M206 to apply a persistent offset to the native home position and coordinate space. // - 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. Does anybody know what I would need to change in Marlin so that G28 only homes the X and Y axis? # define Z_RAISE_BETWEEN_PROBINGS 3 // How much the extruder will be raised … It works EXCEPT the mosfets for fan0 and fan1 blew, but fan2 still works. I don't think normal homing does the multi-probe, but I'm not sure about that. It's also the case that this particular setting is only allowed for ENABLE_AUTO_BED_LEVELING. At this point I've just gotten into the habit of raising the hotend 10mm before I restart g28/g29. Actual behavior: [What actually happens] Weâll occasionally send you account related emails. ... #define Z_RAISE_BEFORE_HOMING 23 // (in mm) Raise Z before homing (G28) for Probe Clearance. Use the controller wheel to adjust Z so that a piece of paper can just pass under the nozzle. I want to use the BLtouch for z homing as well as bed leveling - so far this looks like it will work fine. Already on GitHub? #define Z_RAISE_BEFORE_HOMING 6 // (in mm) Raise Z before homing (G28) for Probe Clearance. I will go through my Marlin config to make sure I didn't miss anything, but I think this is the case. Marlin.zip. Weâll occasionally send you account related emails. 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. Printer homes but does not... qwewer0 - Thank you for copying what you could get. The attached configs are the last of maybe 5 attempts to get this working. This is good for machines whose beds fall when Z is powered off. 2) Limits after homing Then I had to change the settings of the travel limits after homing. Anyway, I have an SKR Pro V1.1 laying around not doing anything. Dang it! #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. With any 3D print, getting a solid first layer sets the scene for the rest of the job. Doing both after a HOME is a BUG. The LCD display should show Z = 0 From the display go to the Menu then Prepare/Move axis/0.1mm/Move Z Now move the Z axis slowly down until the nozzle is the right distance from the build plate (folded piece of paper or thin card). This issue has been automatically locked since there has not been any recent activity after it was closed. privacy statement. 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). Also, re-reading the bug description I said "with or without safe homing", but I have had safe_homing defined for a long time. As a side-effect, X and Y homing are required before Z homing. See examples below. Lifting the nozzle before homing x,y is a goody to jump over the bed mounting screws/clips. #1748 has the Z axis raise before homing X and Y, but still homes Z last. I have posted my marlin code for my autobed leveling below. Expect the printer to home, and then raise Z_AFTER_HOMING distance. Contact me Directly we can work out the details. Guten Morgen in die große weite Welt und diesen Tag möchten wir mit einem Artikel rund um die neue Marlin Software starten. 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 cant increase the HOMING_FEEDRATE because its a prusa i3 and the speed is already at the maximum. When Click to Begin appears, press the controller button to move to the first point.

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 // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). Successfully merging a pull request may close this issue. I got a fresh copy of Marlin 2.0.7 (I used bugfix before) and configured it for my CR-10S using settings from my "old" version as a guide. The current position is adjusted to align to the new home offset values. Yes, you should apply the requested Z rise after the proper function. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. on Repetier-Host. https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Configuration.h#L447. MBL uses the mesh to compensate for variations in height across the bed. I then set Z at zero, G92 Z0. There is no probe, and no levelling of any kind defined in Marlin.
