Interesting; I’ve had an mk3s for years now (which i bought specifically to avoid the tinkering necessary with other brands at the time) and apart from dealing with a couple of blockages (probably due to a cheap roll of filament) it’s been totally reliable and hassle-free. I think I’ve had it recalibrate itself maybe three times amongst hundreds of prints. I wish it had automatic print head adjustment to deal with flexible filaments, but that’s about it.

What is it you see with your P1S that’s better?
