First off I am not a Arduino expert, I can fumble around and usually get my result eventually, however I have never tackled something as complex as the Marlin firmware to the level I am thinking I might need to…
So this is a multi part ask (one is it technically possible with the, second where should I start looking)
I have a TAZ 4 and I have upgraded to a dual extruder and have flashed the firmware as such…
However I also have a E3D v6 Extruder that is set up on a single extruder mount.
What I ultimately like to do, is via the LCD menu be able to:
Swap from a Dual extruder to single extruder config,
Also in doing so I want to change the thermal resistor type to accommodate the the E3D v6, and change the behavior of the secondary extruder fan (to be a constant running fan whenever the extruder temp is over 35c (this is the fan for cooling the extruder) While being able to control the primary extruder fan to operate normally (for PLA or other printing benefited by extruder fan)
What I am looking to do seems easy enough via re-flahsing the firmware each time I change… however major hassle.
