Oh I see

I will see what happens with the 3mm on my cnc.

I am starting to set it up now

I guess I need a controller for the stepper.

Also some material for testing. I suppose I should have ordered that at the
same place I got the extruder. Nutts I forgot.

I suppose I need a some suppliers for that. Plasto-filament.

No, it allows you to use smaller-diameter nozzles, which in turn gets you

In theory you can print faster because there's less volume of material to
heat on-the-fly.


If your positioning system isn't up to the job though,
