An odd thing started happening on my second extruder. I had to shut it down suddenly and ever since, the temp on the second reads too high. At idle, it shows 70 when the other extruder and bed read 20. It seems to warm up when I turn it on, but it won't really go any lower. I swapped cables and even switched 1 and 2, but it doesn't change so it seems like something in the board or firmware. I reflashed the board, but that didn't change it either. Anyone have any ideas.?
Unplugging the ribbon cable (at the rigidboard end) results in the temp reading dropping from 70 down to 65. It acts like it is has an incorrect thermistor setting. I don't know if it relates, but before I shut it down that time it was using extruder 2 for single color prints and now it is using extruder 1 for single color. One step forward and two steps back since I don't think I can do dual prints at the moment.
