After many attempts, I continue to not receive readings from the thermistor no matter what I do. Thank you for any help/experience you can offer. I have re-wired everything, so I know the connections are correct. Multimeter shows resistance on the thermister wires to the board so the connect works. I'm still not getting a reading from the thermistor. I've recompiled marlin from the latest printrbot firmware multiple times. I changed the firmware name and used M115 to make sure the firmware is on the board. Is it possible that printboard F rev 5 needs a different firmware? Or that the thermistor that ships now with the e3d is not #define TEMP_SENSOR_0 5 I'm getting the error message below. Printrbot Simple purchased in the fall of 2015 with printboard F rev 5. --------------------------------- Recv: Error:0 Recv: : Extruder switched off. MINTEMP triggered ! Changing monitoring state from 'Operational' to 'Error: 0: Extruder switched off. MINTEMP triggered ! ' Recv: Errorrinter stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
You've hit the wrong forum section (this is for the bigbox printer) If the printrbot firmware is based on Marlin then yes it should be 5. In the config files you could temporarily disable the mintemp check so you can see what reading you are getting (is it 0 or just very low) http://wiki.e3d-online.com/wiki/E3D-v6_Troubleshooting#Misconfigured_thermistor.2Ftemperature
Thank you for moving the post. I removed the stock thermistor wires and ran new thicker gage wires for the thermistor. This has fixed the problem. No clue why since resistance was there, but it is fixed now. Thank you again.
