It's 80's vintage, analog XY pen plotter, there's a mylar low-compliance
drive belt, mine apparently stretched then dove into the drive gear,
ruining it beyond all repair.
Does anyone know where to get replacement parts? I have the old belt
(pieces) so I can get dimensions. (It's about 3mm wide, 2" diam,
yellowish thin mylar).
Pens are enough trouble to find, I fear for the machines life for lack
of drive belt.
(I tried fabricating replacements, it's a tight application; since it's
a servo closed-loop, I think grooving it for an O-ring will make it
hunt.)
