z safe homing not centered

My BLtouch probe won’t center in the bed. Uncomment Z_SAFE_HOMING. If you then add a G92 then this position will become the home position for the print. In that case, X zeros (albeit to MAX), and Y zeros (again forward) as normal. I have an Ender 3 with marlin 2.0.1. heroMe fan duct. #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). #define Z_SAFE_HOMING_Y_POINT (Y_MAX_LENGTH/2) // Y point for Z homing when homing all axis (G28) #endif. It’s goes to the “center” but it’s just off. The offset will be updated after homing the Z axis, in the next step. Here is some related settings: From the endstops, firmware defined values exist to give the printer head the offset to the home position, also known as origin (X=0, Y=0). 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. // For DELTA this is the top-center of the Cartesian print volume. Question. So it will then be in the position that you want. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z … What could help is a little bit of G-Code right after the Homing. Step 5. The Homing is a G28. I do not have a probe to calibrate the z offset but I have all 6 endstops. (Question) BLtouch not homing exactly center of bed. EDIT - don't forget to save and upload Marlin to your board when finished. This prevents your Z homing from occurring without prior X and Y homing. I tried changing the offsets in the firmware but no success. My problem is. It is a Cartesian based 3D printer, using Marlin firmware and Pronterface software. I have just built my first 3D printer, and I am having some problems. Homing is the process where the machine finds all the limits of the 3 axis (at the endstop switches), to have a common reference point for each axis. So adding these two lines should fix it. A new home offset value has been saved to EEPROM, and confirmed. //#define MANUAL_X_HOME_POS 0 //#define MANUAL_Y_HOME_POS 0 //#define MANUAL_Z_HOME_POS 0 // Distance between the nozzle to printbed after homing. And since I always like to do HOMING in the center of the bed for safety, I activate the Z_SAFE_HOMING option. With the offset now added and saved to EEPROM, -8 position becomes the new zero position, giving the Z axis a total of 88mm of travel, as the case with my 3d printer. I believe WHERE Z homes is defined in the config.h file. When using an auto bed leveling sensor like you are using you should consider this remark: If using a Probe for Z Homing, enable Z_SAFE_HOMING also! which gives me X= 95 and Y = 84, But instead, by Z axis is homing on . If stepper drivers time out, X and Y homing will be required again. That will move your Y Axis 10 mm right after homing. The values you should use need to correspond to the actual offset from the homing point to the origin of the bed (0,0). Because he has the zero points all FUBAR, it won't auto level correctly. 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. With auto bed leveling, the head moves (supposed to) into the center of the bed to home Z. You can see it drop the microswitch. I left Z_SAFE_HOMING enabled and instead of going at the middle of the bed, it goes at the top end right corner ({30,30} instead of {15,15}).I have the feeling the distance is multiplied by 2 for some reason. Just add a G1Y10 after that. I realized something else when disabling BLTOUCH. Without this, you may accidentally miss the bed when homing Z. As a side-effect, X and Y homing are required before Z homing. Goes to same point. My problem is homing the 3D printer.
