How do I set up my file for the Anycubic Kobra 3?

Drop it here. It opens in Convert with the Anycubic Kobra 3 and Anycubic Generic PETG picked, and nothing converts until you click Convert.

Which build plate should I use?

Anycubic Generic PETG sets a bed temperature for each plate:

  • Smooth PEI plate: 80 °C
  • Cool plate: 60 °C
  • Engineering plate: not supported

Why is my PETG stringing?

Lower the nozzle toward 220 °C, the floor Anycubic Generic PETG declares, and lengthen retraction (Prusa Knowledge Base). Wet PETG strings more, and Bambu Lab dries it at 60 to 65 °C for 8 hours in a forced-air oven (Bambu Lab wiki).

Why does PETG print so slowly?

Anycubic Generic PETG caps flow at 10 mm³/s, and the slicer slows any move that would push more plastic than that (slicer source).

Why won't my PETG stick?

Anycubic Generic PETG heats the bed to 80 °C, so if a part still lifts, clean the sheet first (Prusa Knowledge Base). On smooth PEI, apply a glue stick first, since PETG can bond hard enough to damage the sheet (Prusa Knowledge Base).

Where do these values come from?

From the profiles OrcaSlicer ships, read at OrcaSlicer v2.4.2 (8500fcd). Where a filament profile leaves retraction unset, the table shows the printer profile's value.
