Mach3 Rotary Axis configuration

On this video tutorial, originally posted in Spanish; is intended to show how I configured the rotary axis on  my CNC router, perhaps will serve as a guide on a similar situation for somebody looking for information on this subject, I am not an expert by any means all the steps that I use in this video I learned online and by trial and error. I start by showing how I calculated the gear ratio, followed by calculating the steps per degree for the main shaft gear
