Straight R axis #1

I was wondering if the R axis has to be curved, or if it could be straight, like say i have a linear actuator aligned with every 5 or so degrees, so that i could have 72 heads (just an example, that’d be hard to fit). I would like to try the theta polar design with electrodeposition for metal printing/milling, but electrodeposition requires extremely slow print times per head to maintain print integrity. I would like to parallelize as much as possible to speed up printing while maintaining slow print speed per head.

Also, i’ve seen that you can merge the theta and z axis to have one motor with high pitch count thread do both, ie have one complete rotation of the theta axis raise the z axis by one mm or so. Do you have any thoughts on how well this would work, or problems with this method?
