LOL... oops.. I meant converted a pen plotter to a Vinyl cutter by replacing
one of the pins with a cutter.
I've done it. I just crammed in a swivel knife into the pen holder
and started cutting. No big deal except for making a knife mount
adapter. The biggest headache was the paper feed. The rock hard
rollers on the plotter would either slip on the smooth vinyl or leave
tread marks when I cranked up the pressure. I finally ended up
machining a set of replacement soft rubber rollers.
The nice thing about pen plotters is that nobody wants them in these
days of large inkjet plotters. I don't have any photos as I sold the
plotters for a handsome profit. Nice project for turning junk pen
plotters that nobody wants into $$$$$.
I gave up on steel blades as I was always sharpening them. Trying to
keep the tip centered was also a challenge when sharpening. I
switched to ceramic knife blades and never sharpened again. There's
also ruby blades, but they're expensive.
Google finds several articles on converting a pen plotter into a vinyl
cutter.
