Heater Error, Extruder Overheat?

[printbus]

I'm not familiar with CTC printers, but there certainly could be an issue with the missing temperature sensor for the right-side extruder if the printer firmware is expecting it to be there. Is there a control panel or firmware means to disable the second extruder?

I'm finding conflicting information on whether CTC printers use a thermistor on the hot end or a thermocouple. If it uses a thermistor, the thermistor resistance goes up with temperature. If the thermistor isn't there, it is as if the thermistor is very high resistance, or reading a very high temperature. This would result in the overtemp error. That, however, would be an error I'd expect the printer to have right away, not waiting until mid-print.

If your printer uses a thermocouple, then maybe that thermocouple input on your electronics is floating around with nothing connected to it, and the electronics eventually picks up a higher voltage on it than normal, tripping the temperature error.

The easiest path forward is likely to connect at least the temp sensor part of the right-side extruder to your electronics.

Hey there. Thanks for all the info, I just tried to hook up the extruder again. First I got a N/A on the right extruder. I wiggled the wire on the extruder and rebooted the printer, and it was showing the right extruder again. Not long after though, the errors popped back up. So obviously my problem is something with the right extruder wiring? If so, that's fine because I don't want the right side hooked up anyway. Would you happen to know the route I should take (maybe on my picture) to get rid of the problem, maybe unplug any wiring that goes to the right extruder in the first place? Thanks again.
