You could try putting (debug, ...) comments in the G-code routines to see where it is getting to.
What happens if you call the subs from the MDI window ( O<turning> call ) ?
If I may suggest, what would be handy is if you put a mode select radio button on that will allow the user to chose between CSS or Feed rate mode. If Feed Rate mode is selected, the input box for CSS could be come the feed rate or there could be a separate input box for feed rate The subs will have to change as well I suppose.
I don mind fixing these little problems but it means that I will rewrite the routines with variable names in order for me to understand. I am not as clever as you with the numbers.

I assume I must have fixed that in my own version, as I have cut many tapers
