How the two machines differ on paper: build volume, process, enclosure, nozzle temperature, launch year and the materials each manufacturer names. This is a specification comparison, not a hands-on test.

CoreXY Kobra with a 250 mm cubic working volume.
The base S1 uses direct extrusion, LeviQ 3.0 and a 320 °C nozzle. Multicolor hardware is sold separately. Anycubic Slicer Next, the mobile app and USB printing are documented; the base machine does not include active filament drying.
