That’s a fair question 
I wear two hats in this forum, my other handle is @sheetcamCS2 , which is sheetcam customer support. Sometime last winter, I had the idea to use my GRBL pp in this thread as the genesis for a sheetcam exemplar pp demonstrating an easy pattern for using custom options, tool options, flat sheet, and conditional (based on plugin enablement) rotary axis function, G93 feedrate option (for rotary), all in one pp. So the separate thread-- Post Processor Example w Custom Options popup window was started. The exemplar quickly became a re-write of the pp I was maintaining in this thread as the GRBL… pp. Honestly, maintaining two versions of similar pps is growing old, so recently I’ve been relying more and more on the exemplar version even for my personal plasma table use. And recently I added a smaller exemplar pp which is without rotary axis function, so it’s easier to read and learn from, as an exemplar should be. That’s why I sent you there. I recommend that you use the exemplar versions, as I suspect they will become the version I maintain most frequently and thus use personally.
