But if I want to control the printer with Repetier-Host or EasyPrint3D, only the axis referencing works, the manual movement of the axes or also the printing does not work. All three axes drive wildly into the stops and then rattle uncontrolled at the same time. The endstops are ignored. Even if just send a simple move-command for one single axis via g-code.
Probably a stupid beginner's mistake, but I've been trying for hours and can't get any further.
Can someone help me out?
Firmware is Marlin 1.1.8
edit: I have now reflashed the firmware. Board version V3 fits. Error is still the same

edit edit: Ah, you have to compile exactly with version 1.8.5 of Arduino, now it works
