Hey Everyone, I could use some help. I have a Mendelmax 1.0 that I purchased and have been using for about a year and a half. Board is Ramps 1.3a. Great printer. Printer was working great. Now all of a sudden, I don't get any feedback from the thermistor on the extruder (Lulzbot Budaschnozzle 1.0, 1.5 or 2.0 - tried them all) or the heatbed. I'm using Repetier, and have also used Pronterface. Both are giving me the same readings. Extruder reads 12 degrees C, Heatbed reads 148 degrees C at startup. Turning them both on doesn't change the temperature, but of course the extruder just keeps cranking up the temperature, to the point of melting down one Lulzbot Budaschnozzle. I checked readings on Resistor or extruder 100KOhm as should be and 5 Ohms on Thermistor. My guess is I messed up something in a configuration file, but can't for the life of me figure out what I did. I also just read the thread about using a USB hub and making sure power is connected. I thought that was it, because my power WAS disconnected. I reconnected it, but to no avail.
Any ideas?
