Hi all,
I have a TAZ 4, which had the single extruder Hotend it originally shipped with, and it was working and printing fine. I later picked up the Dual Extruder hotend and went through the process of upgrading the firmware for dual extrusion. I have been happily printing ABS / HIPS with it now for a while.
However, now I want to switch back to the single hotend for a bit (which has a fan) and dedicate this original hotend for printing PLA. When I did the swap and turned it on I just get a “ERR: MINTEMP” message on the display when I power it on. I reconnected to the original “black” cables coming from the power supply.
My question to you is it possible (supported) to swap between these hotends, and if so is there a setting or something I need to flip to get it working again?
I also noticed one some other threads that some folks said it could be a disconnected or broken wire, but I don’t see anything obviously disconnected, and it was packed away with care ? Any troubleshooting tips folks have would be welcome.
Thanks,
Steve
