Reply To: Extruder Heater Problem



Not sure What you are asking. If you plug the thermistor into the ramps stack if it shows the right temp you are okay (room temp is about 25C), as for the heater you can give it 12v directly for a few seconds and see if it gets warm, if not no go. You could have a mosfet issue though they usually screw up in the on position, meaning always adding heat, or maybe a poly fuse blew and you are getting no power.
