This is the emails between the YouTuber YGK3D and Anycubic, it seems like they won’t send 3D printers to reviewers who mention their GPL3 license violations.
tl;dr Anycubic uses open-source software for their firmware, but doesn’t make it public as per license agreement, and they don’t seem to be friendly to anyone who calls this out.

To be fair their printers (P1S and H2D) are reliable workhorses, I cant remember if I ever had a failed print and they are basically in 24/7 operation since a year. Never had to do any maintenance.
I can’t get my p1p off the cloud. It’s a supported function. It just refuses to work if I use it. I cannot connect it to Ethernet or USB either. Almost like this thing was intentionally gimped
All my friends who have one rave about the reliability. I can’t get one on principle. They’re all at the mercy of Bambu’s closed source firmware which means you’re always only one automatic update away from a required subscription.
Keep mine offline for that reason and I dont really need a firmware update (as long as they are not software locking replacement parts in the future, but in that case I am happy to trash the printer and never look back, its already payed itself of 100x)
I got gifted a P1S, so I use it. But I stopped updating the FW and use Orca Slicer with the printer in LAN mode. Not optimal, but better than completely giving the control away to Bambu Lab
You should maybe do
At least grease the z axis and clean the dust of the x and y axes
Yes I do this of course, with maintenance I meant deep cleaning stuff, unscrewing panels, tightening belts, replacing gears etc.
Oh yeah,
You should maybe tighten the belts every 3-6 months or so (depending on your usage) and the extruder gears will wear out at some point
They generate a lot of waste plastic on multicolor.
I exclusively print functional engineering stuff so single colour and whatever colour is the cheapest lol
