Dang it! For machines with both Z max and min endstops, there is no caveat. I’m using dual endstops on the X and Y axis, and no endstop on the Z axis. YAY. Yes, you should apply the requested Z rise after the proper function. It compiles but I am not in a position to test on a actual machine atm. Denn vor knapp 3 Stunden wurde ein „Big Update“ veröffentlicht und Marlin steht ab sofort in Version 2.0.6 zum Download bereit. Description. Without this, you may accidentally miss the bed when homing Z. You will need to make sure software endstops are DISABLED for Z after adding the probe. // - Prevent Z homing when the Z probe is outside bed area. Printer homes but does not... qwewer0 - Thank you for copying what you could get. Part 7. Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. Lifting the nozzle before homing x,y is a goody to jump over the bed mounting screws/clips. Since my proximity sensor is placed right of the extruder, see the attached picture, I had to limit the X_MAX_POS to 130. Update: Tested on my E5+ which also has probe and levelling defined. (kill() called! By clicking “Sign up for GitHub”, you agree to our terms of service and Since the bed is only 120mm square, manual levelling is about as easy as it gets. https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Configuration.h#L447. Contact me Directly we can work out the details. 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. 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. I've already saved the mesh and have the mesh loaded during prints after G28. When I do a G28 to test the print head goes as expected to the front left of the print bed. Marlin.zip. It works EXCEPT the mosfets for fan0 and fan1 blew, but fan2 still works. (See https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Configuration.h#L447 ). For this topic, I have two problems with my 3d printer. With any 3D print, getting a solid first layer sets the scene for the rest of the job. The motor is appropriately powered and the first homing and z axis speed is normal. 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 Notes. I have posted my marlin code for my autobed leveling below. Please open a new issue for related bugs. I notice this at x and y axis but they definitely are not as slow as the z axis. 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. #define Z_SAFE_HOMING. privacy statement. This prevents your Z homing from occurring without prior X and Y homing. idk) will let you print without homing Z as long as it knows where zero is. 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). Restored what we could from discord log below. I had a little scare when the first time I tried it, it didn't lift. 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. Already on GitHub? 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). 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). 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. #ifdef Z_SAFE_HOMING After homing the 3d printer again, the Z axis will be updated, and the -2.5 position will become the new zero position. It's also the case that this particular setting is only allowed for ENABLE_AUTO_BED_LEVELING. 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. If we have the sensor on a servo we need some space. My E-mail is currently on my github profile (but wont be for long!) I'll try it out on one of my other printers "just to make sure". You signed in with another tab or window. Anyway, I have an SKR Pro V1.1 laying around not doing anything. My lead screws are 8mm/revolution. In my logical way of thinking it makes sense to me that if you define a height to raise before homing, and if the hotend is too close to the bed (when homed) for the servo (if using a servo) to extend, but can't because the hotend isn't being raised before starting the homing process, then something is wrong. Successfully merging a pull request may close this issue. G28 disables bed leveling. Unfortunately no. ... #define Z_RAISE_AFTER_PROBING 0 //How much the extruder will be raised after the last probing point. I don't suppose there is a place to send one that could be used by all developers, or at least pooled somehow???? Go to step 7 to test the new settings. ellensp - I hovered over your id and is says you are want boards to work with. I am just keeping it as a backup, but now I think if I needed it I might just buy something anyway. Marlin, BLTouch, z endstop as a backup? Guten Morgen in die große weite Welt und diesen Tag möchten wir mit einem Artikel rund um die neue Marlin Software starten. We’ll occasionally send you account related emails. If stepper drivers time out, X and Y homing will be required again. parent 3b4c89e4 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 Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. 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. #define Z_RAISE_BEFORE_HOMING 6 // (in mm) Raise Z before homing (G28) for Probe Clearance. Mesh Bed Leveling (MBL) allows interactively measuring a Z height mesh without a bed probe. So, are you confirming that Z_RAISE_BEFORE_HOMING is not being applied before homing X or Y? 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. At this point I've just gotten into the habit of raising the hotend 10mm before I restart g28/g29. I don't think normal homing does the multi-probe, but I'm not sure about that. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. Unzip and put in Marlin/Marlin/src/module/probe.h That certainly looks like what the code is doing, but I haven't tested it. Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). Wait for Homing XYZ to complete. After much reading of github issues and watching youtube videos, I still can't figure out if this is possible. Uncomment Z_SAFE_HOMING. Sign in There are few questions I have with respect to the Z level in case of Manual Mesh Bed levelling. [BUG] Baby-stepping screen not accepting user change, fixes #19579, Z_AFTER_HOMING ignored with no probe. Apparently Marlin (or Octoprint? I am using the latest version of Marlin and it gave me nothing but issues, printer wouldn't move or home at all. And reopened. Based on bugfix branch. Steps to Reproduce. // - If stepper drivers time out, it will need X and Y homing again before Z homing. See examples below. The text was updated successfully, but these errors were encountered: Edited: Seems github ate the contents. The attached configs are the last of maybe 5 attempts to get this working. Use the controller wheel to adjust Z so that a piece of paper can just pass under the nozzle. Carefully give this this new probe.h a try probe.zip This is good for machines whose beds fall when Z is powered off. When Click to Begin appears, press the controller button to move to the first point. Expected behavior: [What you expect to happen] Expect the printer to home, and then raise Z_AFTER_HOMING distance. I see the Z raise only after G28XY finishes. ... #define Z_RAISE_BEFORE_HOMING 23 // (in mm) Raise Z before homing (G28) for Probe Clearance. Also, re-reading the bug description I said "with or without safe homing", but I have had safe_homing defined for a long time. Not even LCD levelling. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. That's what I expected but I was hoping anyway. #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . My Configurations. on Repetier-Host. but my Z is at the bottom in the first time, so the Z can not go down any more. When homing, with or without safe homing, the Z axis completes the double "probe", but the nozzle stays ON the bed. 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. 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. Use M206 to apply a persistent offset to the native home position and coordinate space. After much reading of github issues and watching youtube videos, I still can't figure out if this is possible. We all work independently mostly from home (but some from their work) and we are planet wide. Then it moves to home X, and it tries to move the Z-axis up to Z_HOMING_HEIGHT, which is set from Z_CLEARANCE_BETWEEN_PROBES if that is defined (which it was for me, and it was 5). I'll confirm it. 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. As noted in #1736 it looks like Z_RAISE_BEFORE_HOMING occurs just when homing Z and only after homing X and Y. Z_RAISE_BEFORE_HOMING only after homing XY?
