Hi everbody,
I've build my own printer using Ramps 1.4, a smart controller and the marlin 1.1.8 firmware. It almost works, but I am facing one 'last' strange problem:
Home Z:
After hitting the z endstop the printer probes for a second time with slower speed. After hitting the endstop, the nozzle is in perfect distance to the bed (as adjusted).
Auto Home:
After hitting the z endstop the nozzles drives ~1mm above the bed and stays there as 0 position. There is no slower speed probing.
Since Auto Home is called from the .gcode file; every print starts at this 1mm position -- resulting in a failed print.
I am struggeling with this problems for some days now. Does somebody have any idea? Do you need more detail?
Attached you can find the Configuration.h and Configuration_adv.h
Best.
