paper spools

I got some spooled paper for my drawbot project!

The idea is it can feed itself. Perhaps I should look at having the Y axis done through a stepper motor driving the spool? I’d either have to drive the paper directly or vary the speed based on the radius of the spool.

I suppose having the stepper drive the spool with a wheel pressing against the outer part of the spool itself solves the problem.

Then I’d only have to implement an X axis. Might be sufficiently simple to have a pen lifter or multiple pens then.

I have a paper cutter but it’s very short.

Any idea how to snip off 18 5/8″ of paper?
