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. I tried setting absolute values here, I've tried doing ((X_min_pos + X_max_pos) / 2). Edit: I've been testing it still and I found that if I set safe homing to 220 X/Y, it acts correctly, as in the probe sits pretty much right on the end stops and deploys the probe. Although its after G28 and not G29 :). I followed multiple threads on this issue but not a single one solved my problem. -- | -- | X | -- | -- SKR 1.3, 1.4 & MKS SGEN L Board Setup Tutorial with TMC2208 UART. To change or obtain your EEPROM settings you need to open Repetier Host (for Linux or Windows, v2.1.3 - the OSX version I tried, v1.1.0, didn't seem to have this functionality). Creality offers the firmware on their website as a .hex file - which is hard to edit. I've set Z_SafeHoming. The idea of Z safe homing is that it is forced to home Z in the middle of the bed (bed size/2) so the inductive probe does not try to trigger in thin air. In your Configuration.h, line 1390, your homing is set to center. If Z_SAFE_HOMING was enabled, and the bed properly dimensioned, it could be that the steps/mm are incorrectly defined. Well occasionally send you account related emails. Now, either hack those into Repetier firmware or use a blank Marlin.ino and the Arduino IDE to customise it. -- | -- | -- | -- | -- Edit 2: Well I figured out the problem. // Travel limits (mm) after homing, corresponding to endstop positions. Scan this QR code to download the app now. Note that, if you cannot or will not flash new firmware, an alternative solution exists to set new incremental offset values using the M206 command IF your current firmware supports this. Which slicer do you use? Can we create two different filesystems on a single partition? This causes some issues such as now the nozzle wipe at the beginning of a print happens right in the center of where the print is supposed to be. I have a runaway problem.

Now on to getting the abl to work First attempt, the probe is off the bed to the side despite having the offset and margin set. ?.X/Marlin into the Arduino folder in Documents (Windows) or Home (Mac). Then when I home the Z axis the bed moves to the center of my print bed (90,90) and does it Z probe. But there is an option in marlin, as morganlowe describes. Correct X/Y at 0,0 due to manual X and Y home. Basically, you want to center the nozzle in the middle of the bed from what I understand from your question. It only takes a minute to sign up. I'm not sure what distribution you're referring to, I built it myself from source. What is you bed size and you safe homing settings set to in Marlin config? This is a consequence of enabling Z_SAFE_HOMING: 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. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). News and information related to the Marlin Firmware used on many 3D printers around the world. This is useful if the toolhead, for example has to move to the center of the bed before Z can be homed. "". Em 15/02/2015 19:48, "doomstrike" notifications@github.com escreveu: Ticket opened: The 3 point auto leveling was working intermittently and the GRID auto level would appear to home, but would not center the probe in the bed.

After battling this for a bit, I managed to get determine the Z-SAFE_HOMING sending to the center of the bed and setting coordinates to 0,0 there. (this was working before), When I do a G28, it correctly does the X, then Y, but now the Z is not done in the center of bed (I have bltouch) and the speed/noise from the Z axis is much higher. rev2023.4.17.43393. When you issue a plain "G28", it'll home X/Y, then move the nozzle to the middle of the bed (plus offsets if you have them defined) before homing Z. Now, we did set Tools>Board:> Sanguino and Tools>Processor:>ATmega1284 or ATmega1284P (16 MHz). I do not have, you should possibly retract the filament before probing Z to prevent oozing. It's not going to the center. For the printer to know the origin of the bed, offsets are defined in the firmware from the end stop locations to the actual origin of the heat bed. Anything in there not look right? Do you recommend to subtract the distance between the probe and the extruder nozzle and modify the Z_SAFE_HOMING_X_POINT value accordingly or there is a smarter way to input that distance in an initialization stage of the code?
