Continuing the discussion from Anyone done a rotary axis on the PRO yet?:
After doing some searching I found out that Sienci LAbs created a rotary axis for there machines, https://sienci.com/product/vortex-rotary-axis/. Here is the electronics part of the system, Electronics - Vortex CNC.
I feel if I get some X-Carve Pro cables and cut them to place the Sienci Labs connector on one end and the other to connect to the x-Carve Y axis motors and controller, for a total of 4 cables. This should work. Thoughts?
