I can't use 2.8 because master has all of the things I need. I'll try a few things though, thanks!

Apparently "Note: your list delivery is currently disabled; it was disabled due to excessive bounces. The last bounce was received on 14-Oct-2022." Which is probably a Gmail thing, and might also be related to a certificate problem at the RTAI end. Neither of my computers wanted to follow the link above.

Wow! Thank you!

Intensive floating point arithmetic in the 5.4 kernel has yet to be tested. LinuxCNC may require some changes as well. I will let the LinuxCNC development team know when it's all set!
