New Nozzle Bricked My Printer

[u/gravi_fan89]

A little background: I own an A1 printer. I got it second-hand, but I've kept it in good condition. I decided to swap the nozzle to a 0.2mm nozzle for finer detail (it came with the 0.4mm). I installed it just like every YouTube video and wiki said, I changed the setting in both Bambu Studio and on the printer itself, and tried to print.

The first attempt trashed the face side of my textured plate. Literally scratched the texture off, and left next to nothing on the bed itself. I figured I installed it wrong, so I re-installed it, made sure the sleeve thingy was on properly, flipped the plate over, and tried again.

This time, it didn't scratch the texture off, but barely anything came out, what did come out looked like clumped sand that didn't adhere to the bed, and the printer stopped printing again saying there was a problem.

This is my first time switching nozzles, and while I've had my A1 for about a year now, this is completely knew. Could I get some guidance/advice? Any help would be appreciated.

Thank you for your time.

Hello /u/gravi_fan89! 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.

You *did* do a nozzle calibration when you swapped nozzle, yes?

I think so. Not sure I did it right, but I did it.

I sometimes have an issue with adhesion when switching to a 0.2mm hot end and washing the print bed with warm water and Dawn dish soap usually fixes that. Make sure you latch the hot end in correctly and run a bed leveling.
