Hello Everyone 

I am having a problem with both my A1 and A1 mini printers. For some reason bother printers will not print / extrude PLA with 2mm nozzles. The printers work with 4mm nozzles but not 2mm nozzles.

I have tried multiple 2mm nozzles and nothing works. I have unclogged all the nozzles many times. I even worked with Bambu support and they couldn't fix the issue. 

My A1 printer used to work fine with 2mm nozzles, not anymore tho.

No surprise Bambu wouldn't replace the printers.

Has anyone had the same issue?

Thank you
Chris
