I have a different problem from what I have seen others have. I have a 18i-TB control using manual guide-i. I have the program working great except for rigid tapping. When I execute the program, everything runs great up until it is time to tap. The live tool spins up and moves to location. Then the spindle stops, looks like it orients itself, and the machine will just sit there indefinitely.

Now, I can reset the program and restart with the tapping operation, no problem. Tool spins up, moves to location, turns off, orients itself, taps the hole, and finished out the program.

I have tried using G94 and G95 feed rates with no change. Of course, I am using guide-i so I am not using a G84 command, it uses G1112 for tapping info and G1210 for the position.

I am stumped as to why it works when executed at the tapping cycle and not when the whole program is executed.

Any help would be greatly appreciated.
Thanks,
T.J.

Anyone have any ideas? I have run out of things to try.

Post the code where it hangs up so we can look at it. Are you calling out
M29 prior to your manual guide i tapping cycle? If not you need to. Here is a one from a program that I have run many times.

Seems like my version of manual guide i is using G1002 for the tapping cycle and G1210 for the positional data. The M29 syncs the spindle with the Z axis. Try this, run the code I gave you as is and see if it runs ok, if not remove the M29 and see what happens. You most likely will not get much help with manual guide i issues, not to many people program with it. We used it exclusively in the beginning to get us up and running fast, then we switched to using a cad/cam system once we figured out what we were doing Hope this is of some help and let me know how things go.

Problem solved. I had to put a spindle stop in before I indexed the spindle even though I was not running the spindle. I was indexing the spindle in the operation before the tapping cycle, but I guess the control thought it was in spindle mode.

Anyway, I added a spindle stop, and no problems since.

Thanks,
