Hi Everyone,
Prusa I3
Printrboard
J-Head Hot End
12v PCB MK2
Repetier Host for Mac
I have been running the printer with no problems until yesterday. After clicking 'Run' the heatbed heats up until it reaches 110c (nothing wrong there); all axes are homed; hotend heats up to 230c and that is where it stops. The print does not start.
Interestingly, the reported heatbed temperature in Repetier does not fluctuate from 110c - even +-0.1c! It's frozen!. I can however, hear the power relay to the heatbed starting and stopping, so it is obviously managing the temperature correctly. The hotend temperature seems to move within an acceptable range slightly above and below 230c.
As a test, I changed M109 to M104 and manually heated up the hotend to 230c and then clicked run. Surprise, Surprise, the print starts with no problems.
Any ideas?? I obviously don't want to continually have to manually heat the hotend.
