[BUG] (MPC settings for Galaxy Toolheads do not adjust filament heat capacity)

[wrathernaut]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

When using the Galaxy universal firmware, MPC settings for all toolheads set heat capacity for 1.75mm PLA filament (0.0056) instead of 2.85mm PLA filament (0.0149). Where the 1.75mm toolhead is the option, and the Workhorse+ ships with the 2.85mm.

This doesn't seem drastic enough to cause the problem (thermal runaway experience by the user) but this bug was revealed while helping out the user in this thread here on the official forums: https://forum.lulzbot.com/t/heating-failed-taz-workhorse-trouble-at-temps-200c/27184

I would suggest making the default heat capacity for the Galaxy Universal firmware to be for 2.85mm filament, since this is what ships with the Workhorse+, and Mini3.

Additionally, the M306 parameters that are set in the Toolhead menu do not change the heat capacity when switching from MET175 to MET285.

Expected behavior

Firmware for the workhorse should default to what is included as shipped - 2.85mm filament heat capacity.

Toolhead menu should switch the heat capacity for MPC.
