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.
Thanks for the ideas, yeah I've tried playing around with the presets and such, and I'm fairly certain the filament itself is good, matterhackers pro PETG.
When I have a moment I'll be trying to make an extrusion tower to test settings.
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.
That is a very good question. There aren't any insane overhangs, just a few tricky spots. I had print he same thing smaller, so I knew it would be okay. I think the file actually mentioned in the notes that you COULD print it without support.
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
