Arc fitting disabled in orca, but receiving unknown command G3/G17 errors

The filament is a Polymaker Polylite PETG, white.

I’ve got the temp(s) above what is recommended by the manufacturer, at 260/90 first layer, and 255/90 other, those are the best results I’ve seen so far while printing a 15mm X 5mm disc. Going super slow on first layer(was at 10mm/s, now going down to 5mm/s).

I’m struggling to get the first layer to stick to the bed(PEI Textured) and not gunk up the nozzle.

Now if you’re asking if I’ve got a setting for arcs under the filament profile. I don’t know that one exists. The start and end gcodes are simply:

; filament start gcode
; filament end gcode 

I’m close to giving up on this Polymaker for now and either move on to our ESD filament, or do some more tests with the Creality PETG to make sure it’s not a different issue.
