A problem with homing
February 09, 2021 04:21PM
Hi I recently discovered this forum, nice to meet you!!
I am trying to build a CoreXY printer and.. i have a problems with the homing of X, and Y axis.

If i activate the homing in the LCD panel, the axis move to the minimun position endstops, but the LCD shows that it is in the coordinates 150X, 150Y, 0Z, the problem is that the extruder is not in those coordinates, it's in the lower left corner. theoretically that is the coordinate 0X, 0Y, but the LCD shows 150X, 150Y. this causes the printer to think that it is in the center of the printing area, and if I send to print anything, when making movements to the left or to the front there will be crashes and it will damage the structure.

in the corresponding section of the code on the measurements of the bed i have:

// The size of the print bed
#define X_BED_SIZE 300
#define Y_BED_SIZE 300

// Travel limits (mm) after homing, corresponding to endstop positions.
#define X_MIN_POS 0
#define Y_MIN_POS 0
#define Z_MIN_POS 0
#define Z_MAX_POS 200

Pd: I have done the same with RepetierHost and the same problem happens, I hope someone can help me
I attach the images about the problem.

No expert but as nobody else replied:-

//Manual homing switch locations:
// For deltabots this means top and center of the Cartesian print volume.
//#define MANUAL_Z_HOME_POS 402 // For delta: Distance between nozzle and print surface after homing.

Yours may be set to 150.
