While multiple nozzle sizes for MMU3 on MK4 are not yet supported, hard-coding nozzle size in the start G-Code is sub-optimal.
I've modified the second line of my own start G-Code from this:
M862.1 P0.4 ; nozzle diameter check
to this
M862.1 P{nozzle_diameter[0]} ; nozzle diameter check
Users still have to go in and change the extruder nozzle size, but this way users don't ALSO have to change the start G-Code. If they don't change the start G-Code, they'll receive a message saying the nozzle size is incompatible on the printer. This can be bypassed, but it gets the user into a bad habit of immediately disregarding these warnings.
