How do I set up my file for the Anycubic Kobra S1?
Drop it here. It opens in Convert with the Anycubic Kobra S1 and Anycubic TPU picked, and nothing converts until you click Convert.
Which build plate should I use?
Anycubic TPU sets a bed temperature for each plate:
- Textured PEI plate: 55 °C
- Smooth PEI plate: 55 °C
- Cool plate: 35 °C
- Engineering plate: not supported
How fast can I print TPU?
Prusa suggests about 20 mm/s for flexible filament and at most 30 to 40 mm/s, or it can clog the nozzle or tangle in the gears (Prusa Knowledge Base). Anycubic TPU caps flow at 3.2 mm³/s, and the slicer slows any move that would push more (slicer source).
Why is my TPU stringing?
Lower the nozzle toward 190 °C, the floor Anycubic TPU declares, since a cooler nozzle strings less (Prusa Knowledge Base). Keep retraction short: Anycubic TPU retracts 0.8 mm, and longer retraction can clog the nozzle (Prusa Knowledge Base).
Do I need to dry TPU?
Yes, Bambu Lab marks drying as required for TPU, at 70 °C for 8 hours in a forced-air oven (Bambu Lab wiki). Wet flexible filament is hard to print (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.
