Add Choice in LCD Menu

Tanuki44

Hello,

I have two possibility :
- I use a triple head with mixing extruder (diamond hotend)
or
- I use three separate heads (two colors and one for support with PVA AquaSolve)

I would like to add this choice in the Extruder LCD menu :

Mixing Extruder (MIXING_EXTRUDER) on / off

Is't possible to change without flashing firmware and how to do?

Thanks for your help.

No, you can not switch in firmware. That flag is resolved at compile time to optimize speed. You could make it a variable and replace all MIXING_EXTRUDER tests with that and reprogram menu to change that variable. Maybe some other things also need tweaking as eeprom has a special extension for mixing case.

Ok, I suspected that a little.
I'm not sure my knowledge allows me to change that way.
