Homing Failure

Fontastic

I am having trouble homing my delta printer. After homing, the X, Y, and Z will all reach the endstop, back off and try to zero back. The problem is, whenever they zero backoff, the screws on the carriage are still pressing the switch, which causes a problem each time I go to home the device (which happens at the start of a print). If someone could please tell me how to fix this, it would be greatly appreciated. I suspect I will have to change the homing sequence but I do not know where I would begin.

Use

#define ENDSTOP_Z_BACK_ON_HOME 20

to give them some space. 20mm is a good start so you can even move a bit left/right without hitting endstop. Important for deltas and reason for many problems.
