Heating automatically stops

Swen

I'm using the repetier software. Everything works fine but when i want to heat my extruder or bed it automatically stops after a few seconds. Does anyone know what the problem could be? 

I'm using the ultratronics pro motherboard

Connect with host/server and watch the log. I guess you run into decoupled message and need to adjust timings. Firmware will tell you why it did it there.
