I guess they are similar to Taz 4, except I don’t see a dual extruder firmware available for Taz 5 anywhere. Also there are no arduino files located in the Taz 5 sub. I am afraid to do any updating until I am sure those are the correct files. Also are there fans available that mount on the dual extruder for PLA?

TAZ 5 = TAZ 4 + Hexagon Extruder + PEI print surface

If you want to use the Dual Extruder with a TAZ 5, you will be able to use the firmware provided with the dually. Just make sure you change the firmware back if/when you switch back to the hexagon extruder.

Ok so I follow the firmware update instructions for the taz 4 and do the arduino updates as well?

edit never mind I see you are saying the controller is the same in the 4 and the 5.

I see now that they are developing a dual extruder with the all metal version. Should have waited for that.
