For some reason this new problem has now started. Ive tried various prints and tried removing and reinstalling repetier host. The printer is a Prusa I3, Windows 7 comp, repetier host, Pla. I can start a print fine everything is great then it just stops, its not stopping at an exact point every time. sometimes line 9 sometimes line 109, When it stops I try to move the extruder with repetier away from the print and its lost connection with the printer and the heaters are staying on until I recconect (unplug or close repetier and reconnect). ANy ideas?
