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.
