ultimaker stops after a while

[shanti 0]

 

The printer stops with bigger models after half an hour or later, the temperature remains high.

The log says following

'Unexpected error while reading serial port: SerialException: 'call to ClearCommError failed' @ machineCom.py:_readline:431

Changing monitoring state from 'Printing' to 'Error: SerialException: 'ca...'

Connection closed, closing down monitor'

Any ideas?

are you printing with a sd card on the ulticontroller or direct usb connection ?

if thats USB maybe the cable is just too long ?

if its sd card, im not sure what the error message could mean, but did you try putting your fingers on the motors after a half an hour ? if they are super hot, they might be getting too much voltage and this will shut down the shop aswell.

I've had similar problems printing through USB so I don't do it anymore. I only use the Ulticontroller. I think the arduino might be sensitive to electrical noise. Or there is some bug.
