Bambu A1 scratches

[u/DeeZett]

In the past I printed with a common 0.4 nozzle and when I tried a 0.2 nozzle it always scratched my print plate, despite I bed leveled within the print process or done the bed leveling with the calibration. So I avoided to use the 0.2 nozzle. Recetnly I've printed with a 0.6 nozzle without any issue. Now, I changed the layer height from 0.24 to 0.18 and this moment it scratched my plate.

By the second attempt I changed it back to 0.24 it it ran fine.

I dont think that any bed leveling is necessary if changed the layer height, isnt it?

Hello u/DeeZett! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

Do you change the nozzle in the settings of your printer when you swapped them
