z safe homing not centered

The Ender 3 homing failed error is one of the more problematic issues you can face due to it entirely stopping the 3D printer from operating and due to there being a few distinct and unrelated culprits that can cause the error that make the fixing process more challenging and time-consuming. You could improve the answer massively by including 1) M503 to get the current Firmware settings. Greenonline also wrote about this in his blog. and our #define Z_SAFE_HOMING_Y_POINT (Y_MAX_LENGTH/2) // Y point for Z homing when homing all axis (G28) #endif. I think this is my issue.

Optional support for Repetier Firmware M163, M164, and virtual extruder. It's not going to the center. marlin has a default offset for the probe, so you should set them to 0 both. Isolating the Bug The only things that seem consistent with the homing bug happening are: AMD based computer used to compile the firmware 2560 Board - Usually the Creality V2.X boards that come in the Ender 5 Plus one from Christian, a German maker also known as "Chaos-Drucker"), we need to first adjust them as needed to fit our needs and then compile them properly (next step!). It worked perfectly. Settings I have set: In configuration_adv.h I have set the first probe location to be 25,25 from zero. Should the alternative hypothesis always be the research hypothesis? I was missing this last step. Thank you for your time to respond and help me. Can we create two different filesystems on a single partition? I changed Z-SAFE_HOMING to: #define Z_SAFE_HOMING_X_POINT (10) . However, Christian did figure out that the Sanguino set to an ATmega 1284P 16bit does work. From How to make changes to the EEPROM data. This parameter must be provided. With these settings we were able to compile the settings. Would you know why the homing would not use the offset I am putting in the firmware?

Homing XY moves to the lower left as it always has, but homing Z moves not only to Z=0, but also to the center of the build plate. "#if ENABLED (Z_SAFE_HOMING), They would have to change this e.g. I have them detailed in my Marlin guide. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). Prints great still, just need to figure out auto bed leveling! The hardest step with the Ender3 was to get the code to actually compile, as it uses an ATmega1284P 16Bit which isn't supported by Arduino natively. Alex. X&Y axes home (fore some reason the X axes des not do the second slower homing procedure, I don't know if it's related) I am able to get it working minus the BLTouch. // Travel limits (mm) after homing, corresponding to endstop positions. -- | -- | -- | -- | -- (As noted on this page.) #define Z_SAFE_HOMING_X_POINT (X_BED_SIZE / 2) // X point for Z homing, #define Z_SAFE_HOMING_Y_POINT (Y_BED_SIZE / 2) // Y point for Z homing, #define HOMING_FEEDRATE_MM_M { (50*60), (50*60), (4*60) }, // Validate that endstops are triggered on homing moves. Does Chain Lightning deal damage to its original target first? If Z_SAFE_HOMING was enabled, and the bed properly dimensioned, it could be that the steps/mm are incorrectly defined. It's not going to the center. 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. Y homes to minimal Y-end stop. In turn, when the bed leveling sequence starts, the sensor is off the bed for the first probe spot.
