Printer has stopped working again

Thought I had overcome a glitch in my Velleman printer. Basically after the bed reaches 50c the extruder begins to rise but stops after about 5 seconds and the submitted print job is cancelled. I can manually set the bed and extruder to their respective temperatures. So it appears to be to do with executing the Goode. I have not changed any setting at all. yesterday it was working fine.

When I manually get the bed and extruder up to temperature and then press run the printer moves by about 1 mm and then stops.
