Any good alternatives to Bambulab printers?

absolutely, see other comments

Don’t want a printer that I habe to tinker with

nope, and this is why I have a P1S and not one of the alternatives (and the one time I did need to tinker, because my AMS’ internal hub unit failed and needed replacing, Bambu CS handled it well and fairly quickly)

this commenter is awful, but I do have to appreciate the person who responded to them with “GPT2, calm down.”

I don’t see any way this is anything but a filament issue, it’s not like your print head could print a layer after the layer on top of it…

fwiw, I’ve had similar issues with some multicolor filaments, I think sometimes they just aren’t made quite right but still pass QA.
