I really don't know what I am doing wrong. Since changing my bed level sensor from left of the extruder to back mount, it doesn't work proper anymore and I have some fundamental thing I don´t understand. My settings:
#define LEFT_PROBE_BED_POSITION -89 #define RIGHT_PROBE_BED_POSITION 90 #define BACK_PROBE_BED_POSITION 145 #define FRONT_PROBE_BED_POSITION 10 #define X_PROBE_OFFSET_FROM_EXTRUDER 6 #define Y_PROBE_OFFSET_FROM_EXTRUDER 60 #define Z_PROBE_OFFSET_FROM_EXTRUDER -1.4
Now the first thing I don´t get is how especially
LEFT_PROBE_BED_POSITION works. Cause when I set it to
11 here (I want it to measure 5 steps from the home) it measures almost in the middle not at the left edge. It seems that I need to subtract from where the printer homes (X99 Y45) which is why I choose X-89 but then it seems that the printer assumes a totally wrong size of the bed and ties to print off the bed...
Here where it measures:
16:02:44.774 : Bed x: -89.00 y: 10.00 z: 1.28 16:02:59.326 : Bed x: 90.00 y: 10.00 z: 1.23 16:03:13.466 : Bed x: 90.00 y: 145.00 z: 1.28 16:03:27.959 : Bed x: -89.00 y: 145.00 z: 1.30
Measures exactly where I want it to but the values make no sense. The first probe is actually about X10 Y10 but the display shows X-95 Y-50 while the above values are from the slicer log. That makes absolutely no sense to me!
I hope anyone can enlighten me.
