I'm doing a rather large TPU test print, which will eventually have PETG parts mixed in with it.
I'm using a Modix dual extruder printer and have TPU in one and PETG in the second extruder, and haven't figured out how I can set it up so each extruder runs at a different print speed.. IE the TPU at 20mm/S and the PETG at 45mm/s so the prints don't take 3x as long as they should.
Other than setting the support speed to 200% and the main speed at 20mm/s, is there a better way to configure it?

If you're only printing supports with PETG and nothing else, setting the support speed modifier to your desired print speed would actually be the simplest way to setup your print.
