Pinout for the 3d Printer unit.
So I’ve been having intermittent machine failures (firmware unresponsive over COM port) which freezes all the motors mid-print, but leaves the heating elements on. I pulled the 3d print head apart to unblock the nozzle after a particularly long time sitting idle, burning the same piece of filament and now that I’ve reassembled it, the arduino reports the temp as -26 degrees and that the milling head is attached. My understanding is that the detection is based on the resistance from the thermistor and either I’ve broken a wire there, or something has short circuited and I’ve cooked the pin on the arduino itself.
Does anyone know the pinout (now that the unofficial forum is down) for the 3d printer head so I can test the resistance of the thermistor with a multimeter before I start pulling apart more of the machine again?
Please upload an image or a list of pins (and let me know which you’ve taken as pin 1) so that I can troubleshoot.
Is this a good question?
