This is very much likely to change - I'm still learning every day!

I used a 500W china spindle for my tests.
Plexiglas (PMMA)
Melts at 160°C (even earlier than your printer's PLA or PETG).
These are the main challenges:
- Make sure the chips leave the flute so they can't friction weld (dust shoe, compressed air)
- Finding the highest cutting volume (diameter*speed*attack) while keeping the tool as cool as possible

Looks good, might be the limit before it shows.

Looks okay, but seems to be the limit. 300mm/min also tested, PMMA was melting.

Too much. Melting after a couple of minutes (Attack 2.00 Speed 100 failed miserably with melting)
|
Cutter diameter of 2.00mm seems to be the most viable method - maybe trying a higher speed is an option?

Works out fine, more speed should be possible.
