. Once I got those set so the nozzle was in the center while homing, I was able to set the probe offset in there and now the probe is nice and centered when homing. 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? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0).

I'm not sure what firmware this board runs, but Marlin has the capability to do a "Z_SAFE_HOMING". * * With safe homing enabled: * * - Allow Z homing only after X and Y homing AND stepper drivers still enabled. 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. This acts as if the Y offset for the probe is being ignored. Enter G28 X, Y, and Z coordinates get assigned a value of 0. Reply to this email directly or view it on GitHub When homing the printer, the hot end carriage will be instructed to hit the (mechanical or optical) end stops. Anything in there not look right?

This is useful if the toolhead, for example has to move to the center of the bed before Z can be homed. Settings I have set: In configuration_adv.h I have set the first probe location to be 25,25 from zero. how do i add the file? Please Help going nuts! That way the question will be removed from the unanswered question queue. The nozzle goes to 25,25 for the first probe spot, which does not work. Why does the second bowl of popcorn pop better in the microwave? just had to pretty much reverse engineer parts of the ender3 XD. #endif I have it after G29 so that it pulls the new Z value back as well. I do not have, you should possibly retract the filament before probing Z to prevent oozing.

Now the homing point should be 0/0. Select export eeprom settings. What is homing? Many thanks. the center of the bed can also be used, and is frequently much more easy to re-calibrate as the heated beds usually have rounded corners or are slightly larger than the actual print area (e.g. Variant 2 means writing the settings yourself or using Repetier firmware to write the files for you. To do this, download the zip from github, then in the Arduino software Sketch>Include Library>Add .ZIP Library and choose the whole zip repository to auto install.

Repatier can't home, Pronter runs out of memory for my 14-18 hour prints :(. #define Z_SAFE_HOMING #if ENABLED(Z_SAFE_HOMING) #define Z_SAFE_HOMING_X_POINT ((X_BED_SIZE) / 2) // X point for Z homing when homing all axes (G28). Anything in there not look right? How do I reconfigure the Home position to have an offset to the 0-positions gained from the limit switches? What it's doing is when I auto home, it homes X/Y, then it should put the probe in the center (110,110,0) but instead it violently flys to X0 and Y comes in some.
