Retired at 62 now 75. Having way more fun with my A1 combo than I did with my Creality Ender 3 V2. But trying to learn as much as possible. Some prints are awesome and if I just stay with generic PLA things seem to be pretty smooth, but I’m having trouble getting the software and machine to accept PETG without the machine telling me that it’s “not compatible” and refusing to print with PETG at all.
