Ahh yes that makes sense

 

The default expression for calculating the feed per rev is incorrect, its using the spindle speed for drilling rather than the positioning spindle speed:

If if I update the expression it works correctly, but I'm not sure why it is posting F0 when the feed per rev checkbox is not selected.

FYI Heidenhain doesn't use feed per rev at all so it kind of redundant here
