Problems getting started: All three axes move in negative direction ignoring end stops

[stancecoke]

I bought an A10 printer used and defective (burned stepper driver and a burned trace on the pcb). I managed to repair it. Directly via the LCD panel I can drive all axes correctly, also heat and extrude.

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

Awesome!!! Nice to see post.

I tried setting min_software_enstops = false
All this does is allow me to go past the end stop while i command the axis to move either through pronteface or the lcd menue.
Homeing the z axis will still not let the z-axis reach the z end stop.
