I want to use my 60 x 90 80 watt machine in a mode which can be described as "continuous web". Briefly, I want to construct a transport for spooled paper, driven by the rotary attachment, and convert MIDI music data into a suitable format to create music rolls which can be used with legacy player pianos. Has anyone tried this kind of application? Is there a better area of the forum to pose this question? Thanks.

Interesting question.
Do any of you real CNC guys know what it means?

Cannot see a problem with doing this I have done similar cutting lengthy paper and vinyl stencils up to 100ft in length, only difference was I used a 2.8w laser diode £70 aliexpress to do the cutting, your problem is the driving of the paper if reeled and pulled roll gets larger so speed increases which would mess up your cut so paper need to be fed through rollers to maintain accurate speed of feed hence correct distances.

Yep, that's the plan. So, assuming I devise a way to command a row of small holes to be cut at a specific X coordinates (which would involve both X any Y axis movement), how do I command the rotary attachment, which normally uses Y axis commands, to incrementally advance the paper (through suitable transport gearing/mechanism) to the next row position?

I just set up a pair rubber rollers spring loaded one direct driven by a nema 23 to pull material through and then calibrated as you would your Y axis changing steps to suit, as far as software concerned it was just a 100ft table.
