I’ve been busy ‘relocating’ my i3 to make it somewhat portable and structurally solid.
Now the question is: what speed do you guys (and gals!) use for a traditional Prusa i3? Up to now my print speeds were more on the conservative side but since it’s more solid now (hopefully) I think i can bring the speed up. I know I can (and will) find this myself but its easier to start from a reference point.
I leave some photos of it undergoing the revamp (still messy…).
