Thermistor Issues
Posted: January 22nd, 2018, 9:09 pm
I haven't played with my printer much in the last couple of weeks as I was prepping to covert from the stock extruder to a bowden extruder. I finally got everything done with my mod and plugged in the new extruder/thermistor combo and the extruder temp is reading 88 on the LCD with the extruder being at room temp. I plugged the old extruder in and low and behold the old extruder is also now reading 88 on the LCD when at room temperature. Before the change over I would read about 22, at room temp, which is 72 F, which is where I keep my house temp.
Any thoughts on what might be going on? I also noticed that my bed temp is also now reading 5, so something is for sure happening as I never touched that sensor or connection. I have tried unplugging the thermistors right from the mother board and the temps don't change, but if I heat up the extruder or the bed, then the temps will rise, but never get below 88 on the extruder and will fall to 5 on the bed.
At this point I am at a loss and wondering if I somehow messed up my motherboard.
