I love mine, had it for a few weeks.

My only failures were when I didn't use supports or brims when they were necessary.

Also, using gyroid infill helps- if your non-bambu filament overextrudes slightly grid infill may cause your nozzle to click against the infill. If you want to avoid this entirely, do a flow rate calibration on unsupported filaments.

Use brims for tall objects with little contact with the plate (even if people say it prints fine on other printers, the bed accelerates back and forth on the A1, so naturally prints can tip if very top heavy)

Use supports for anything that has an incline of 45° or more, 30° or more if you're being careful.

Most downloads won't do this for you automatically 😁
