G'day Guys, joined a few years back but have mainly lurked in the back ground. I am 3/4 the way through building a specialized 6 head CNC router to manufacture timber fishing lure bodies, the Machine has Y & Z but X is rotational (A) and revolves 6 chucks that hold the wood. This is my first dealings with rotational cnc so forgive my naivety (I do have a small normal cnc though). What I am trying to calculate is how to make the chucks (A) rotate 1:1 with the tool path created in Vectric Aspire wrapping. Currently the chucks do many many full revolutions while the tool path in Mach3 turns through one 360 cycle. I am guessing this isn't possible to achieve in setup and that a reduction gearbox of sort is needed? Is there a way without to much trial and error that I can calculate the reduction needed? My reduction from the pulley on the stepper motor to the chuck is 2.6:1, any help would be greatly appreciated, Regards Paul.
