Hello @t.adkins, I am guessing that you are wanting to use a multi-axis tool path to cut the bevel. As you know multi-axis tool paths are not supported with a plasma cutter.
You can use a milling cutter in this case, but you will need to make modifications to the post processor in order to support a milling cutter and then control when the plasma is turned on and off, since milling operations have no concept of a power setting and onPower is never called to change the power state. The determination of when to turn the power on is usually made at the start of a MOVEMENT_CUTTING move and then turned off at the start of a MOVEMENT_LEAD_OUT move.
You can see an example of controlling the power (or in this case additive) in the Kuka Robotics post. Refer to the onMovement and setAdditiveProcess--- functions. We do not have a post processor that allows milling tools to be used as plasma/waterjet/laser cutters.
