The printer breaks off printing and stops
responding
If the printer breaks off the printing process there are three possible reasons. First, it should be
checked whether the power supply was interrupted. The problem may also be caused by an
interruption of the data connection to the computer, the crashing of a program or a disconnected USB
cable.
If neither is the case, it is possible that the Pololu shut down due to overheating. This can easily be
validated by touching the Pololu heat sink. Thirdly, the Ramps fan might not sufficiently cool the
Pololus or the potentiometer may be set too high.
If the potentiometer can not be decreased due to possible step losses, it has to be examined whether
the motor works against an increased resistance, e.g. some misalignment of the rods after moving or
bumping the device. This resistance would have to be eliminated and the potentiometer readjusted
afterwards.
