Hello, my machine used to work fine, until I started to need heating.( previously i worked with just a pen)
but once i attached the thermistors and enabled them on the firmware the extruder heated up once and started cooling down almost immediately. after that everytime i would try to connect to my printer, i get the error:
Error:MAXTEMP TRIGGERED
I've researched it and i know that this happens when the thermistor circuit is short, and because the resistance is close to zero the machine thinks that its very hot, and I know that if the circuit is open and in the firmware its enabled, the error would be the same only instead of MAXTEMP it would say MINTEMP triggered.
HOWEVER, once i unplugged the thermistors, from the ramps board, and tried to connect, i would still get the same error, so I've deduced that perhaps the thermistor pins are shorted on the ramps. so i unplugged everything from the arduino and tried connecting, and i STILL got the same error, saying that there's a short. i even dissabled the thermistors in the firmware and later uploaded a clean version of it, but i still get the same error the moment i try to connect, i tried uploading a blink and fade sketches, and it worked fine. i even bought a brand new arduino board and i still get the same error.
PLEASE can anyone tell me whats wrong here?
