Diy rotary setup

hi there i use candcnc system on my diy plasma and im looking to add a rotary to it, ive seen a few videos of people adding skateboard wheels etc etc to roll the tube, has anyone designed their own? and does the sheetcam plugin do all the maths regarding rolling the round tube?
many thanks in advance.

I can’t speak to the mechanical DIY setup you mention as I have not done this, but it makes sense for round pipe. As for ‘all the math…’, yes, sheetcam Rotary plasma plugin will handle that.
