I made today the first cuts of my "micro-rider" , widly inspired by the MPCNC and low-rider needle cutter, and moebeast's Foam Ripper.
I tried and do even simpler and less costly with two stepper motors and one servo, a bunch of bearings and a few wheels. Almost all of the rest is On the shelf components.(Video on Youtube).
It adapts to a wide rangle of surfaces, and can go from really small to full sheet of DTFB (but don't have that size this side of the pond).
I may try in a few days to also cut vinyl stickers with it, or later laser ? But in both cases, I'll need to find a better servo since this one has some kind of jitter. (or use a light stepper a la 28BYJ...)
