I’ve had an X1C for a few years now. My router blocks my printer from communicating outside of my home network and my firewall blocks the slicer. I haven’t had any problems. It sucks that the company is being shitty but they really do make exceptionally good printers. I’m glad Prusa is at least sort-of keeping up with them. I had a Prusa Mk3S for several years before I got my Bambu, they’re extremely reliable.
