Might be a setup error on my part, but the P1S has had more print quality problems than my A1m. Also, when iterating on new drafts, I find it useful to have 2 printers to print staggered versions, reducing my wait times. Again, if you don’t have the resources to keep it, sell it by all means. After all, that’s what I did. But i do sometimes miss it’s simplicity and ease of use. Going back to your first question, i just never updated my a1m, nor my p1s, so they both worked fine with Orca slicer. The app and online functionality still works

I started it with the A1 mini, then got a Sovol sv08, then aP1S, after selling the A1m. If you can afford it, keep yours, I miss mine. Yes, its too small for some things, but unbeatable for everything that fits on it’s build plate.

Is there a list of printer (brand) specific communities?

Apply baby powder on the build plate, shake of the excess. Seems to fill in the gaps. I can’t recall where i learnt about it, but it works really well. Stickiness on textured pei is comparable to pla or petg.

I used to throw the textured pei plate with the sticking print into the freezer for 15 min, made removal much easier. Now I just add baby powder onto my build plate, and remove the print at room temp. Much easier, a little messier
