I have always wanted to try printing larger, using a bigger nozzle - just got around to swapping to a .6mm in my MK3S+. Printed a gift for a childhood friend. 300% size. Took just under 10 hrs. With the slicer settings on .4mm it was over 17hrs.
When it works, it’s pretty great. I’ve got a weird overextrusion issue to fix on my MK3S+ with the 0.6 nozzle, but the prints themselves are tougher and faster.
Ever since Arachne came out .4 became obsolete for me. If you play with the settings right a .6 can produce nearly the same small details while being way faster for infill etc.
Can I ask what settings you had to hone in?
I lowered minimum wall width and wall transition length.
I also use .6 as my standard nozzle. Since the stuff I print is usually custom brackets and cases, a bigger nozzle would be even more ideal. The problem is my stock heating can’t keep up with anything larger than a .6
What printer and hot end?
It’s an ender 3 pro with the stock hot end, but it’s also running klipper and prints at 60mm/s
