If you were wondering, 1mm nozzles work

I dont think I changed nozzle size in the slicer. Just line width and height settings. I can look at it tomorrow but I’m 99% sure I just set the printer to .8 nozzle and built my own profile. I just scaled up settings from the smaller nozzle.

Start with the .8 nozzle profile and set line width to something like 1.04 or 1.05 for a 1mm nozzle or 1.44/1.45 for a 1.4 nozzle. Be prepared to print slow. The overall print times may not change at all. Its handy for vase mode though.

Id love some info on slicer, how do you get around the setting nozzle size under printer parts in the bambu lab device pannle? Iv got a 1mm nozzle but cant send to printer as it needs me to select from ether 0.4 0.6 or 0.8 without the opption for telling my p1s that it has a 1mm installed

Read the previous comment. Now you can start with a .2 profile
