I bought this printer for our robotics team two years ago and I have never been able to get a print out of it. My problem is that the first 1/4" of the print prints fine, then it stops extruding the PLA. I walk back in there and I have nothing above the print job and nothing coming out of the extruder.

I am using the base settings from Makerbot Desktop for the settings.

Extruder temp 195

Base temp 60

extruder speed 90 mm/s

Any suggestions??
