The P1S Combo is the safest pick for a first multicolor machine because everything you need arrives in one box: an enclosed CoreXY printer and a four-spool AMS feeder. The enclosure keeps drafts off the part and holds in noise and fumes, which helps when you move beyond plain PLA. The listing quotes 500 mm/s and 20,000 mm/s2 acceleration, and automatic bed leveling takes the most common first-layer failure off your list.
The headline speed is a ceiling, not a cruising rate. Reaching 500 mm/s needs several millimeters of travel at that acceleration, so short moves and corners never get there. What matters for two-color work is the AMS: it holds four spools, so a two-color print leaves two slots free for a backup spool or a support material. Against the A1 Combo, the P1S costs more and gives you the enclosure and a sturdier frame.
Ownership is mostly about the AMS. Keep spools dry, check the filament path for bends and clean the nozzle wiper area. The ecosystem around the model library and slicer is the other reason to pick it, since a color-change workflow lives or dies on software. Print a small two-color calibration piece first, because a good first result tells you the purge setting and spool path are sane.
What works
- Enclosed body keeps drafts and noise in
- AMS holds four spools for two-color jobs plus spares
- Automatic bed leveling removes first-layer fuss
- Large model library and slicer ecosystem
Watch out for
