Greetings all!
So I've recently finished construction of my sae prusa mendel, however I'm having some trouble with the firmware.
I'm running the latest sprinter on a sanguinololu 1.3a, with pronterface.
I've got my xyz motors and endstops working perfectly, and my hot end thermistor reads a temperature (not using a heatbed yet), however I cannot get the pin output for the heater control to toggle at all!
I've tried modifying the firmware to use one of the expansion pins instead, this did not work.
I've looked at the output directly from the pin on the atmega1284p with both my scope and multimeter, and the pin simply stays at 0V.
Any ideas?
