4th axis wiring

[DaBooBear]

Here is the guy I got my info from.

4th axis option

I just set up mine to run a rotary as the Y-axis and it works fine. I’m sure you could run it as the X-axis as well. I’m using vcarve and only using it for the laser so far. So I just modified the post processor for the laser by adding in a wrap Y to A and then went into the controller and changed the M1 from Y to A and inputted new settings for the rotary axis. It works for me being able to laser engraved on tumblers so far.
