Ok gdit we are building a versatile art/pen plotter take 2. Last time life intruded.
Here are the rails. 3 X 60cm, 2 X 50cm. V slot 2020 aluminum extrusions.
There’s a formula for what size rails give what plot size but this cat is on my lap and I can’t look it up.
It will be a3 capable but more square. This will be very slowly posted but follow along for follies.
