I want to finish up a printer I started a while back (ORD-Bot, Azteeg X3) and got stuck on getting the extruder working.
The big question that I thought I’d ask this community is: should I go 3mm or 1.75mm?
This won’t be a bowden setup, so I know that’s one reason that people use 1.75.
I already have a couple of good working printers, one using 1.75mm (Kossel Pro) and the newest one using 3mm (TAZ 5), so I have a good collection of both sizes filament around.
I had thought the original reason for the migration to 1.75 was that the 3mm filaments were from pre-existing tech and not sized reliably, and 1.75 was the bright new standard future for FFF. But the TAZ is still using 3mm and people seem to be settling on a 2.85mm standard there.
Does anyone have insight into where the industry is going with filament sizes? And maybe why Luzbot stuck with 3mm?
