One more thing: yes it is a lot of work to do the programming, but once
it is done you have it forever. I probably spent 80 hours doing mods,
testing, etc. I've also cut our one-off machining time to nothing.
Every time we machine a one off part we have an hour or two or three.

Every machine we build from now on will use this software with these
updated features. The payoff for doing this work is really good.
