I’m having some trouble with my AO-101 atm; The temp reading for the extruder in pronterface is for some reason stuck at around 93.2C. It does vary slightly when I set the temp, but not nearly as much as the actual change in temp. The range of readings is between 93 and 95 C more or less, and even when totally cool the reading never drops below there. At a temperature high enough to contact melt ABS pronterface read 95.5 degrees.
My first thought was a bad heater fuse, but that isn’t the case, and it doesn’t really make sense because the heater is still functional and responsive to settings but any setting above 96 sets it into an infinite heating loop because the reading never reaches 96. Also the fuse had no burn marks.
Next I figured it must be the thermistor, because that’s in charge of the extruder temp sensing, so I replaced it and checked the connections and everything looks fine, but the issue is still happening.
I tried hard and soft restarts on the printer and computer, and I’m pretty well out of ideas. Anyone have an idea what’s going on?
