Creality Ender-3 V3 SE in PrusaSlicer
PrusaSlicer has no Creality Ender-3 V3 SE profile, and preslice cannot make one.
Does PrusaSlicer ship the Ender-3 V3 SE?
No. Its Creality bundle holds the CR-10 V3 but no Ender-3 V3 SE. OrcaSlicer, Creality Print and Cura ship it: 220 × 220 × 250 mm bed, 0.4 mm brass nozzle, one extruder.
Why not convert to PrusaSlicer anyway?
Any PrusaSlicer profile Convert picks is another printer's. Its G-code targets that printer, not your Ender-3 V3 SE, so a converted file does not help.
What should I use instead?
OrcaSlicer shares PrusaSlicer's layout: PrusaSlicer to OrcaSlicer. Cura works too: PrusaSlicer to Cura. See what Convert cannot carry.
