Variable pitch belt driven spindle

Might be.
Thank you.

Congratulations!
How well does it work? (little video?)

yes it's nice to see the end result for the next person trying something similar.

It works quite well, actually! I am surprised at how quickly the belt can be adjusted, and how little lag/overshoot there is in the adjustment.

I need to make a youtube account and start sharing stuff again. This forum is the extent of my social media presence right now!

I ended up making quite a few tweaks to the program, as I found out that "while" loops and a RTOS don't mix well

While cutting out my spindle encoder mount, I did have a bump at the end of the program... the system locked up on me, much like when I was using while loops, right when the program ended (just after the mill moved to the park position). Unsure if that's my program causing problems or not. More testing, more chips

Thanks cmorley for encouraging me to do the custom realtime component. This really opens up a lot of opportunities!
