Hi,
is it possible to remove an unused extruder and hot end from i3 pro c?
I already have removed the stepper, but if I remove the temperature sensor the printer Fail.
If I upload Pro b firmwere, would it work?

Hi，it is not recommended that you remove them.

I know that is not recomanded, but I'm upgrading my printer, and the double extruder is a big limitation,
if is possible to add an extruder on the pro b, why isn't possible to remove one from pro c?
if I change the firmwere it would work, or it will make strange things?
