How do I set up my file for the Original Prusa i3 MK3S?
Drop it here. It opens in Convert with the Original Prusa i3 MK3S and Generic PETG picked, and nothing converts until you click Convert.
Why does PETG print so slowly?
Generic PETG caps flow at 8 mm³/s, and the slicer slows any move that would push more plastic than that (slicer source).
Why won't my PETG stick?
Generic PETG heats the bed to 90 °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 PrusaSlicer ships, read at PrusaSlicer 2.9.6 profiles (3f2935e). Where a filament profile leaves retraction unset, the table shows the printer profile's value.
