Display shows 0 for hotend temp. Installed new "original" 12v hotend off Amazon. Resistance of thermistor is 104. Trying to trace wiring back to main board, but there is a "gantry adapter" board plugged into the T0 pins. And 2 blue/green wires plugged int T1 slot. Any help?
The machine arrived with no hotend, just the mounting pieces. So I guess the donor had this issue, and gave up.
