marlin z raise after homing

to your account. My E-mail is currently on my github profile (but wont be for long!) 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). This issue has been automatically locked since there has not been any recent activity after it was closed. I suspect it's because of a fast increase in Z speed that I don't necessary need. I see the Z raise only after G28XY finishes. By clicking “Sign up for GitHub”, you agree to our terms of service and Uncomment Z_SAFE_HOMING. 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 The only tool required is a piece of paper or a feeler gauge. If stepper drivers time out, X and Y homing will be required again. 1) My Z axis speed is very slow. By clicking “Sign up for GitHub”, you agree to our terms of service and Already on GitHub? 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 Printer homes but does not... qwewer0 - Thank you for copying what you could get. 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). #1748 has the Z axis raise before homing X and Y, but still homes Z last. Dang it! It's also the case that this particular setting is only allowed for ENABLE_AUTO_BED_LEVELING. If we have the sensor on a servo we need some space. # define Z_RAISE_BETWEEN_PROBINGS 3 // How much the extruder will be raised … I have tried changing MAX_FEEDRATE , MAX_ACCELERATION , HOMING_FEEDRATE . This prevents your Z homing from occurring without prior X and Y homing. So, are you confirming that Z_RAISE_BEFORE_HOMING is not being applied before homing X or Y? Go to step 7 to test the new settings. 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. When I do a G28 to test the print head goes as expected to the front left of the print bed. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. To see how slow my Z axis is moving check 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). With any 3D print, getting a solid first layer sets the scene for the rest of the job. Just traded one for the other. I'll confirm it. Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. #define Z_SAFE_HOMING. Im using RAMPS 1.4 on my Hypercube with Marlin 1.1.5. 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. I've already saved the mesh and have the mesh loaded during prints after G28. G28 disables bed leveling. And reopened. Successfully merging a pull request may close this issue. I am pretty sure it works. I've run into this a few times over the last week trying to double- and triple-verify the bed-leveling bug. 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 is required before G29, M48, and some other procedures.. 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. You signed in with another tab or window. // - 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. It works EXCEPT the mosfets for fan0 and fan1 blew, but fan2 still works. I am just keeping it as a backup, but now I think if I needed it I might just buy something anyway. Just home the machine. Please open a new issue for related bugs. For this topic, I have two problems with my 3d printer. I'll try it out on one of my other printers "just to make sure". My Configurations. Closing. 2) Limits after homing Then I had to change the settings of the travel limits after homing. Since the bed is only 120mm square, manual levelling is about as easy as it gets. Have a question about this project? 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’m using dual endstops on the X and Y axis, and no endstop on the Z axis. I don't have access to this type of controller board at all. 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. Wait for Homing XYZ to complete. The attached configs are the last of maybe 5 attempts to get this working. Expect the printer to home, and then raise Z_AFTER_HOMING distance. I don't think normal homing does the multi-probe, but I'm not sure about that. This effectively shifts the coordinate space in the negative direction. Actual behavior: [What actually happens] // 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. At this point I've just gotten into the habit of raising the hotend 10mm before I restart g28/g29. Hi guys! privacy statement. Apparently Marlin (or Octoprint? When homing, with or without safe homing, the Z axis completes the double "probe", but the nozzle stays ON the bed. I notice this at x and y axis but they definitely are not as slow as the z axis. #define Z_RAISE_BEFORE_HOMING 6 // (in mm) Raise Z before homing (G28) for Probe Clearance. (See https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Configuration.h#L447 ). I am using the latest version of Marlin and it gave me nothing but issues, printer wouldn't move or home at all. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. There is no probe, and no levelling of any kind defined in Marlin. That's what I expected but I was hoping anyway. Expected behavior: [What you expect to happen] MBL uses the mesh to compensate for variations in height across the bed. Weâll occasionally send you account related emails. 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? As noted in #1736 it looks like Z_RAISE_BEFORE_HOMING occurs just when homing Z and only after homing X and Y. Expected behavior: [What you expect to happen] Expect the printer to home, and then raise Z_AFTER_HOMING distance. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Yes, you should apply the requested Z rise after the proper function. Anyway, I have an SKR Pro V1.1 laying around not doing anything. 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 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. Part 7. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). This will let you adjust the Z to a negative number for your offset. Mesh Bed Leveling (MBL) allows interactively measuring a Z height mesh without a bed probe. 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). As noted in #1736 it looks like Z_RAISE_BEFORE_HOMING occurs just when homing Z and only after homing X and Y. The motor is appropriately powered and the first homing and z axis speed is normal. I will go through my Marlin config to make sure I didn't miss anything, but I think this is the case. Without this, you may accidentally miss the bed when homing Z. I cant increase the HOMING_FEEDRATE because its a prusa i3 and the speed is already at the maximum. // 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 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. Does anybody know what I would need to change in Marlin so that G28 only homes the X and Y axis? on Repetier-Host. 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. It compiles but I am not in a position to test on a actual machine atm. Have a question about this project? #define HOMING_FEEDRATE_Z (8*60) #define EEPROM_SETTINGS. // - Prevent Z homing when the Z probe is outside bed area. 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. The current position is adjusted to align to the new home offset values. Use the controller wheel to adjust Z so that a piece of paper can just pass under the nozzle. Marlin.zip. I want to use the BLtouch for z homing as well as bed leveling - so far this looks like it will work fine. I'll try again tomorrow. ellensp - I hovered over your id and is says you are want boards to work with. * Note the Z axis value on the display it should be something like … Unzip and put in Marlin/Marlin/src/module/probe.h I then set Z at zero, G92 Z0. 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. You will need to make sure software endstops are DISABLED for Z after adding the probe. YAY. Doing both after a HOME is a BUG. Printer is a Wanhao i3, newly upgraded with an SKR 1.4 turbo board and BLtouch sensor. 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. Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. to your account. The text was updated successfully, but these errors were encountered: For 'save homing' is a requirement that x & y are homed. idk) will let you print without homing Z as long as it knows where zero is. Guten Morgen in die große weite Welt und diesen Tag möchten wir mit einem Artikel rund um die neue Marlin Software starten. My printer is a Monoprice Mini V1 with a lot of mods, including a 32-bit controller and TMC2209 drivers. Marlin, BLTouch, z endstop as a backup? privacy statement. Remember most of us are volunteers, working in our own time. Weâll occasionally send you account related emails. Add 2 // in front of the MIN_SOFTWARE_ENDSTOP_Z line in your Configuration.h file as shown below. I created a PR so it will be fixed for all, moving forward. #ifdef Z_SAFE_HOMING 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). 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. Sign in Based on bugfix branch. For machines with both Z max and min endstops, there is no caveat. I had a little scare when the first time I tried it, it didn't lift. There are few questions I have with respect to the Z level in case of Manual Mesh Bed levelling. When Click to Begin appears, press the controller button to move to the first point. (kill() called! I moved the function move_z_after_homing() out of the #ifdef block. 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 have posted my marlin code for my autobed leveling below. Z_RAISE_BEFORE_HOMING only after homing XY? 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. ... #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???? Unfortunately no. I will just make sure on my Ender 5 Plus too. Restored what we could from discord log below. Well If you want to send it. ... #define Z_RAISE_BEFORE_HOMING 23 // (in mm) Raise Z before homing (G28) for Probe Clearance. As a side-effect, X and Y homing are required before Z homing. Contact me Directly we can work out the details. 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). That worked, Thank you. The text was updated successfully, but these errors were encountered: Edited: Seems github ate the contents. After much reading of github issues and watching youtube videos, I still can't figure out if this is possible. This is good for machines whose beds fall when Z is powered off. When homing z the switch has to be unswitched! Description. I don't know what happened, but I had everything in it. #define Z_AFTER_HOMING 10 appears to be ignored. Lifting the nozzle before homing x,y is a goody to jump over the bed mounting screws/clips. 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.
