Hello

I just installed the dual extruder head for my original Taz. Did the Firmware updates and have it opened in Cura.

When I click print, an error is generated “Error: 1: Extruder switched off, MAXTEMP triggered!”

I am hoping someone can point me in the right direction to troubleshoot.

Thanks!

Original TAZ? The Dual Extruder is noted as only being compatible with TAZ 4 & 5.

If you have a TAZ 4 or 5, the indicated error means that either the hotend thermal sensor is faulty or not hooked up correctly (broken wire, etc.)

Also the origional Taz is 12v, the dual extruder kit has 24 volt heater cores.
