but my Z is at the bottom in the first time, so the Z can not go down any more. For machines with both Z max and min endstops, there is no caveat. privacy statement. privacy statement. Just traded one for the other. The text was updated successfully, but these errors were encountered: Edited: Seems github ate the contents. G28 disables bed leveling. I see the Z raise only after G28XY finishes. There is no probe, and no levelling of any kind defined in Marlin. I then set Z at zero, G92 Z0. Printer homes but does not... qwewer0 - Thank you for copying what you could get. Marlin, BLTouch, z endstop as a backup? Actual behavior: [What actually happens] As noted in #1736 it looks like Z_RAISE_BEFORE_HOMING occurs just when homing Z and only after homing X and Y. So, are you confirming that Z_RAISE_BEFORE_HOMING is not being applied before homing X or Y? Nevermind my previous post. Restored what we could from discord log below. Unfortunately no. Mesh Bed Leveling (MBL) allows interactively measuring a Z height mesh without a bed probe. Use the controller wheel to adjust Z so that a piece of paper can just pass under the nozzle. Already on GitHub? 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. Steps to Reproduce. (See https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Configuration.h#L447 ). Use M206 to apply a persistent offset to the native home position and coordinate space. #1748 has the Z axis raise before homing X and Y, but still homes Z last. 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 There are few questions I have with respect to the Z level in case of Manual Mesh Bed levelling. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. At this point I've just gotten into the habit of raising the hotend 10mm before I restart g28/g29. The attached configs are the last of maybe 5 attempts to get this working. Wait for Homing XYZ to complete. Configs, descriptions, even a video. Contact me Directly we can work out the details. I'll try again tomorrow. Since the bed is only 120mm square, manual levelling is about as easy as it gets. I don't know what happened, but I had everything in it. We’ll occasionally send you account related emails. 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. Without this, you may accidentally miss the bed when homing Z. Doing both after a HOME is a BUG. Actual behavior: [What actually happens] 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. // - 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 this topic, I have two problems with my 3d printer. Apparently Marlin (or Octoprint? # define Z_RAISE_BETWEEN_PROBINGS 3 // How much the extruder will be raised … idk) will let you print without homing Z as long as it knows where zero is. I don't have access to this type of controller board at all. Successfully merging a pull request may close this issue. If we have the sensor on a servo we need some space. Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. This has been a big bug for me, I ended up modifying the LCD menu etc to only issue G28 X Y, otherwise I would end up with head crashes all the time since my Z servo endstop could not deploy. This prevents your Z homing from occurring without prior X and Y homing. Expected behavior: [What you expect to happen] I don't suppose there is a place to send one that could be used by all developers, or at least pooled somehow???? 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. By clicking “Sign up for GitHub”, you agree to our terms of service and 2) Limits after homing Then I had to change the settings of the travel limits after homing. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). #define Z_AFTER_HOMING 10 appears to be ignored. ... #define Z_RAISE_AFTER_PROBING 0 //How much the extruder will be raised after the last probing point.
