I moved this to a new thread


Roxy directed me to this forum and the Beckdac fork from issue#2040 about the ABL bugs.

I've uploaded the Beckdac to my Ramps 1.4 on a Mendel90, the Y endstop is at Y max and the X endstop is at X max (back right of the bed)

When I send a G28, homing takes place at the back right and then when I send G29, there is no movement in X or Y and the same point is probed each time. I've tried switching the origin from front left to back right with no change. EEPROM and chitchat are disabled.

I also tried a M48 L 10 which Roxy suggested elsewhere and there was no movement in X and Y.

Even with safe Z homing enabled, homing and probing is at back right.

I able to manually jog X and Y but they both stop a bit short of the bed edges.
I've attached a link to my configuration.h and Marlin_main.h and will be grateful for any assistance in fixing this.
