In my last blog I detailed the conversion of a manual rotary axis into a CNC rotary axis. I finally got some time to mount the rotary axis on the mill, configure the stepper in Mach3 and run it through some tests. The parameter for the g-code command to position the rotary axis is a positive or negative number ranging from 0 to 360 degrees. Positive numbers rotate clockwise and negative numbers rotate counter clockwise.
I started by creating a 3 dimensional object using Solidworks and designed a projectile that will eventually be milled in metal for a coil gun project that I’m working on. I decided to do the cut in wood since this was the first project using the rotary axis and I wasn’t sure how it would work out.
