Hi,
to my knowledge Mach4 does not have any canned cycles. The lathe profile does however have canned cycles, and they are supplied by MachMotion not NFS.
As a consequence the code is in complied form, that is to say you cannot view/edit the source code.
I'm guessing here, but I think the two files (CannedCycles.mcc and CannedCyleImages.mcc) in Mach4Hobby/Wizards folder are in fact placeholders for the corresponding files in the Lathe
Canned Cycles sub-folder.
