marlin z raise after homing

Not even LCD levelling. I will go through my Marlin config to make sure I didn't miss anything, but I think this is the case. idk) will let you print without homing Z as long as it knows where zero is. Anyway, I have an SKR Pro V1.1 laying around not doing anything. You signed in with another tab or window. Lifting the nozzle before homing x,y is a goody to jump over the bed mounting screws/clips. #ifdef Z_SAFE_HOMING Already on GitHub? 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. Carefully give this this new probe.h a try probe.zip Without this, you may accidentally miss the bed when homing Z. For this topic, I have two problems with my 3d printer. Restored what we could from discord log below. Uncomment Z_SAFE_HOMING. Hi guys! By clicking “Sign up for GitHub”, you agree to our terms of service and https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Configuration.h#L447. A quick check of the config revealed that it wasn't enabled on this machine, so enabling and re-flashing and all is good. I am using the latest version of Marlin and it gave me nothing but issues, printer wouldn't move or home at all. Have a question about this project? I had a little scare when the first time I tried it, it didn't lift. I suspect it's because of a fast increase in Z speed that I don't necessary need. I will just make sure on my Ender 5 Plus too. I'll try it out on one of my other printers "just to make sure". #define Z_AFTER_HOMING 10 appears to be ignored. ... #define Z_RAISE_BEFORE_HOMING 23 // (in mm) Raise Z before homing (G28) for Probe Clearance. Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. Nevermind my previous post. Remember most of us are volunteers, working in our own time. My lead screws are 8mm/revolution. I just tried this on my CR-10S which DOES have a probe and levelling, and now it does not raise Z after homing. I don't think normal homing does the multi-probe, but I'm not sure about that. ellensp - I hovered over your id and is says you are want boards to work with. I’m using dual endstops on the X and Y axis, and no endstop on the Z axis. # define Z_RAISE_BETWEEN_PROBINGS 3 // How much the extruder will be raised … Already on GitHub? Successfully merging a pull request may close this issue. 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. 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? I am just keeping it as a backup, but now I think if I needed it I might just buy something anyway. This effectively shifts the coordinate space in the negative direction. Doing both after a HOME is a BUG. This will let you adjust the Z to a negative number for your offset. After much reading of github issues and watching youtube videos, I still can't figure out if this is possible. boelle changed the title [BUG] HOMING_BACKOFF_MM confused with Z_AFTER_PROBING [BUG] [Bugfix 2.0.x] HOMING_BACKOFF_MM confused with Z_AFTER_PROBING on Nov 24, 2019 Sign in #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. parent 3b4c89e4 As noted in #1736 it looks like Z_RAISE_BEFORE_HOMING occurs just when homing Z and only after homing X and Y. Expect the printer to home, and then raise Z_AFTER_HOMING distance. That worked, Thank you. 1) My Z axis speed is very slow. 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. 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 Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Configs, descriptions, even a video. I want to use the BLtouch for z homing as well as bed leveling - so far this looks like it will work fine. Press the controller button to save the Z value and move … My printer is a Monoprice Mini V1 with a lot of mods, including a 32-bit controller and TMC2209 drivers. If homing is needed the LCD will blink the X Y Z indicators. So, are you confirming that Z_RAISE_BEFORE_HOMING is not being applied before homing X or Y? The text was updated successfully, but these errors were encountered: For 'save homing' is a requirement that x & y are homed. to your account. Dang it! I don't know what happened, but I had everything in it. 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). It works EXCEPT the mosfets for fan0 and fan1 blew, but fan2 still works. I don't have access to this type of controller board at all. At this point I've just gotten into the habit of raising the hotend 10mm before I restart g28/g29. Denn vor knapp 3 Stunden wurde ein „Big Update“ veröffentlicht und Marlin steht ab sofort in Version 2.0.6 zum Download bereit. The attached configs are the last of maybe 5 attempts to get this working. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. Weâll occasionally send you account related emails. 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. When I do a G28 to test the print head goes as expected to the front left of the print bed. 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. Notes. but my Z is at the bottom in the first time, so the Z can not go down any more. Since the bed is only 120mm square, manual levelling is about as easy as it gets. My Configurations. 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. to your account. Based on bugfix branch. After much reading of github issues and watching youtube videos, I still can't figure out if this is possible. 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. That's what I expected but I was hoping anyway. You signed in with another tab or window. 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). on Repetier-Host. Just home the machine. There is no probe, and no levelling of any kind defined in Marlin. I have a system with two Z axis motors and it happend sometimes that I want to level the X axis by rising it all the way up. * Note the Z axis value on the display it should be something like … YAY. Mesh Bed Leveling (MBL) allows interactively measuring a Z height mesh without a bed probe. Please open a new issue for related bugs. I am pretty sure it works. Description. Actual behavior: [What actually happens] I see the Z raise only after G28XY finishes. MBL uses the mesh to compensate for variations in height across the bed. The text was updated successfully, but these errors were encountered: Edited: Seems github ate the contents. Steps to Reproduce. Unzip and put in Marlin/Marlin/src/module/probe.h I have tried changing MAX_FEEDRATE , MAX_ACCELERATION , HOMING_FEEDRATE . If stepper drivers time out, X and Y homing will be required again. Unfortunately no. 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. I notice this at x and y axis but they definitely are not as slow as the z axis. Sign in 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. // - 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. After homing the 3d printer again, the Z axis will be updated, and the -2.5 position will become the new zero position. [BUG] Baby-stepping screen not accepting user change, fixes #19579, Z_AFTER_HOMING ignored with no 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. This is good for machines whose beds fall when Z is powered off. Successfully merging a pull request may close this issue. With any 3D print, getting a solid first layer sets the scene for the rest of the job. See examples below. As noted in #1736 it looks like Z_RAISE_BEFORE_HOMING occurs just when homing Z and only after homing X and Y. 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. Marlin.zip. 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. 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. #1748 has the Z axis raise before homing X and Y, but still homes Z last. I created a PR so it will be fixed for all, moving forward. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). Have a question about this project? Yes, you should apply the requested Z rise after the proper function. I'll confirm it. Also, re-reading the bug description I said "with or without safe homing", but I have had safe_homing defined for a long time. Expected behavior: [What you expect to happen] I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. Guten Morgen in die große weite Welt und diesen Tag möchten wir mit einem Artikel rund um die neue Marlin Software starten. Go to step 7 to test the new settings. Update: Tested on my E5+ which also has probe and levelling defined. ... #define Z_RAISE_AFTER_PROBING 0 //How much the extruder will be raised after the last probing point. privacy statement. Just traded one for the other. 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 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). It compiles but I am not in a position to test on a actual machine atm. If we have the sensor on a servo we need some space. 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. I don't suppose there is a place to send one that could be used by all developers, or at least pooled somehow???? When homing z the switch has to be unswitched! I'll try again tomorrow. This issue has been automatically locked since there has not been any recent activity after it was closed. Z_RAISE_BEFORE_HOMING only after homing XY? 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. // - If stepper drivers time out, it will need X and Y homing again before Z homing. Use M206 to apply a persistent offset to the native home position and coordinate space. 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. G28 disables bed leveling. By that logic you should implement Homing backoff after probing. 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). And reopened. I've already saved the mesh and have the mesh loaded during prints after G28. I then set Z at zero, G92 Z0. 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. Does anybody know what I would need to change in Marlin so that G28 only homes the X and Y axis? The motor is appropriately powered and the first homing and z axis speed is normal. Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. 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). To see how slow my Z axis is moving check I've run into this a few times over the last week trying to double- and triple-verify the bed-leveling bug. // - Prevent Z homing when the Z probe is outside bed area. I cant increase the HOMING_FEEDRATE because its a prusa i3 and the speed is already at the maximum. #define Z_SAFE_HOMING. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Homing is required before G29, M48, and some other procedures.. 2) Limits after homing Then I had to change the settings of the travel limits after homing. Closing. As a side-effect, X and Y homing are required before Z homing. This prevents your Z homing from occurring without prior X and Y homing. #define Z_RAISE_BEFORE_HOMING 6 // (in mm) Raise Z before homing (G28) for Probe Clearance. Part 7. I moved the function move_z_after_homing() out of the #ifdef block. That certainly looks like what the code is doing, but I haven't tested it. When homing, with or without safe homing, the Z axis completes the double "probe", but the nozzle stays ON the bed. My E-mail is currently on my github profile (but wont be for long!) When Click to Begin appears, press the controller button to move to the first point. Apparently Marlin (or Octoprint? Use the controller wheel to adjust Z so that a piece of paper can just pass under the nozzle. The only tool required is a piece of paper or a feeler gauge. privacy statement. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. There are few questions I have with respect to the Z level in case of Manual Mesh Bed levelling. Setting up Marlin 2.x.x on my first time CoreXY Hypercube build and where do you establish "home" in configuration.h . (kill() called! Contact me Directly we can work out the details. (See https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Configuration.h#L447 ). I have posted my marlin code for my autobed leveling below. 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). The current position is adjusted to align to the new home offset values. Expected behavior: [What you expect to happen] Expect the printer to home, and then raise Z_AFTER_HOMING distance. // 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 By clicking “Sign up for GitHub”, you agree to our terms of service and Weâll occasionally send you account related emails. For machines with both Z max and min endstops, there is no caveat. Well If you want to send it. 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. Since my proximity sensor is placed right of the extruder, see the attached picture, I had to limit the X_MAX_POS to 130. It's also the case that this particular setting is only allowed for ENABLE_AUTO_BED_LEVELING. Wait for Homing XYZ to complete.
