Before going in to detail about my issue, I am using a LulzBot Taz 6 with a DualExtruder v3.
I have been using a DualExtruder v3 and have had some issues with it. I recently had to unscrew some pieces of the printer head and found that the thermistor on my DualExtruder v3 was loose/frayed. After noticing this, I wanted to try to flash the firmware of the control box for the printer back to the single extruder firmware so I could continue to use the single extruder that originally came with my Taz 6. Unfortunately, I was unable to flash the single extruder firmware because of this thermistor issue. The error I received was “E1 Err: MINTEMP PRINTER HALTED” when the DualExtruder was connected. I know I need to have the DualExtruder connected to the printer in order to flash the single extruder firmware, but I unable to do that now because of this issue. Is there any way to clear the firmware on the control box so I am able to flash the single extruder firmware afterwards without needing the DualExtruder connected? Right now I am unable to do anything with my printer. Any help is appreciated.
