Thread: G98 G99 retract plane

Ok, got both G73 and G83 cycles working the way I want. The Q value had me messed up not sure why but its resolved. Oh replacing G30 with G0 at the end of the cycle worked slick.



Thanks for all the help!

Why would the G30P1 affect your drill cycle?

It doesn't. Changing the G30 that is normally used to cancel a canned cycle to a G0 keeps the spindle from stopping each time between canned cycles.

Ahh, gotcha. I've never seen a G30 used in that fashion.

Hopefully you won't. Sorry I meant G80

There is something else to watch out for on the Okumas. If you use the M53/G71, you have to assign a new G71 for every canned cycle. The G71 is actually modal. So, if you use the M53 without specifying a value for G71, the control will take the last know value for G71. That may be a good number, but it also could be a really bad number.

Just a heads up. I used the G0 trick on all the Okumas.

Thanks for the heads up, I know I have a lot to learn.

Interesting about the G0 at the end of the canned cycles. Learn something new everyday.

Well I'm happy to report that now that I got the canned cycles working the way I wanted and this morning finished the post processor, we're finally knocking out some parts. The job we're running now used to take 9:20 on the Hurco now its down to 5:30. Poor kid was buried up to his neck in parts that need hardware installed and packaged for shipping, so I cut the rapids back to 75% before he dropped dead on the spot.

So far I'm pretty impressed with the machine overall but have a lot to learn.
