hi thanks for that but I'm still not getting any results. mach reads the spindle speed fine. Ive been through the write up on threading and the Z axis still sits there and does nothing. the only other thing i can think of is maybe there is some kind of conflict mach and the computer I'm using. i am completely lost on this and starting to find it a bit frustrating. Ive tryed using g32 threading with no result.

hi people I'm having problems trying to cut threads on my orac lathe, recently converted to run from mach3. I did have some problems at first calibrating the spindle speed and have now over come this. the problem Ive got is when trying to cut a thread the Z axis does not move. The spindle starts, the tool moves into start position and then just sits there and does nothing. I have been using the wizard to generate the Gcode G76 Ive played around with all i can think of and nothing seems to work. When using turn diagnostics plug-in it reads the rpm OK but everything else has 1.#INF

yea i have been playing about with that. also the spindle pully ratio. ive set it at 0.7. I got this number from the max spindle speed of 2000rpm and max motor speed of 1400rpm. so 2000/1400= 0.7 am i right in doing it that way? seems to of helped a little bit.
