Small update: I made a free online version of the OD turning cycle, so you can try it without installing anything.

Enter stock and finished diameter, length and cutting data - it shows the passes in a 2D view (same simulator as in the program) and gives you a ready .ngc for LinuxCNC (G7 or G8, G54-G59). The calculation runs on the server and is the same as in the program, line for line. No sign-up, no email.

The other 11 cycles are still only in the program. If you try the online one, I'd like to hear what is missing or wrong - especially from those who turn on LinuxCNC every day.
