Printer

PrusaXL

How to reproduce

Load attached project
Under multimaterial set wall type to Cone
Slice
No cone shape generated
Size of the prime tower is trippled to quadrupled vs 2.3.1
Setting the wipe tower to a specific filament increases the tower size even more

Playing with the prime tower width and prime volume (even all the way back to 30mm wide and 5mm prime volume) does NOT bring it back down to 2.3.1 level
Enabling the new tower interface features does nothing. These settings below are NOT visible on a 5 tool XL
Purge into prime tower is DISABLED yet the prime tower is still massive

Actual results

See reproduction steps. Current implementation effectively cripples multimaterial on a multi-toolhead like the XL simply due to size. Prime tower in default config takes up almost 2 full buildplate tiles and 85g of purge.

Expected results

Prime tower size in multimaterial multi extruder to be of the same size as in 2.3.1
