I am sorry for all the people having problems, but my Prusa mjni is finally just workjng and happily printing all the stuff I throw at it. Its been having issues here and there forever. I just figured out that the hotend has not been assembled correctly (heatbreaker to nozzle seal was weak) which became a greater issue when switching to a 0.25mm nozzle. Now after I fixed it, it is just awesome :)
My A1 Mini damaged 2 plates the stock textured and high temp smooth, when I first got it by freezing and locking up. A firmware up date has appeared to have fixed the issue. It’s been a year since it last happened, but I still don’t fully trust it anymore. Bambu makes decent hardware, poor software, and has dubious business practices.
On the other hand, my 7 year old Prusa Mk3s has never had an issue that wasn’t directly traceable to me. Even after converting it to run Klipper, it’s still every bit as solid and a tank that might not be quite as fast the Mini, (though Klipper and the input shaping has pushed the print speeds to over 100mm/sec), it’s the printer I trust to still be using 10 years from now.
