I am thinking of adding a rotary axis to both my laser and mill machine. My plan would be to make the rotary unit something I can move between the 2 systems. I have been looking around for ideas on how to control the unit on each systems, but getting very confusing and even conflicting info. Can GRBL run this, what would be better. I know I will have to change out the controllers, but was thinking I could use the 3 axis board from the mill on the laser. What are your thought everyone?
