I have just print the rigid coupling without problem.
I think the STL of endstop was badly downloaded.
The problème to restar a new print after stoped begin always by crash of nozzle and retract of filament
Question 1: the rigid coupling is not very round (it can be a form of an egg ) . How to do? Must be set in advance of the engines ?
Question 2: at the start of printing, I have to adjust the distance from the nozzle to the bed (using the Z adjust knob).The engine is not always agree. Sometimes I can tune height during printing, sometimes the Z motor resists.
