The post that I'm using can support a rotary axis?
no, Hopefully Les will add it in the SheetCam post for you to test.

Yes I'm in contact with him now. He needed a way to wanted a way to set Pierce height in the gcode.
I've replied with this information. thought id post it if others are interested.


To separately control the pierce height from the profile. add the following in the G&M Code,

DEFINE <PIERCE_HEIGHT> 0.2 ;Sets Pierce Height to 0.2

0.2 is an example, >0.2 can be changed to the desired pierce height

This will need to be done after the M65, but sometime before the first M61. It will apply to all M61's in job as long as M65 is not called again.

This is the post processor that les from sheetcam made for me.
The rotary axis is B.
and the post is also switching between the X axis and the Y axis.
This post is working with the THC.

Here are more videos of the rotary cutting with normal speed and the post compressed file.
I've made today a new prototype rotary attachment cause the previous one wasn't accurate enough.
In about a month I will receive all the fiber laser equipment and then the games will really begin 🤩

M26 /B or whatever your rotary axis designator is. You can add this to your .hom file and it will set the rotary home to it's current position.
