Heating Failure

I am brand new to 3D printing. I have a Hictop Prusa I3 that I assembled, leveled and tested. I successfully printed an small box using an SD card holding the GCODE generated from Cura 14.12 and tried to print a small project. About 10 minutes in to the printing of the project the LCD displayed "Heating Failure". I was unable to get he display to change by turning or pressing the control knob. I powered down the printer and tried again. This time I made sure the Head and Bed came to tempature and watched as the project started again. I left after the printing it looked to be going well. When I returned the LCD again showed Heating Failure.

Can someone please tell me where I need to look or do you know what my issue may be? I've attached the Gcode files is that helps.

I don't know much about your specific machine as mine is an Anet A8, but I would think that you have a problem with either the extruder or bed thermistor. Disconnect them from the control board and take a resistance reading across each. If they differ then one has a problem, on the Anets they are 100kohm and it's probable that yours are as well. If they both read the same then move the extruder about the bed by hand and see if at some point the resistance varies or goes to open circuit. The same check on the bed thermistor. This should help to track down the fault.

Talked with a friend of mine who works in a CNC shop. He said I was running the filament to fast for the small printer/heater head. I cut the speed from 50 to 20 and now I'm printing!

You may have a bad connection to your hot end thermistor, turn on the heater and wiggle the wires
