Bug - Deep Drilling expanded cycle feed rates incorrect
I went to run a program I had previously run before and the positioning feedrate for the drilling cycle is F0(line 36) when is should be F150
If I change the feed rate to feed per rev in the tool tab then it outputs a feed rate but its only F37 when it should be F150

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
