Post changes for Rigid Tap G95-G94

[SLJ]

Guys and Gals

I'm trying to setup my post for rigid tapping on a vertical machine center with Fanuc 21i controler. The post is a much modified MP_EZ. I've gotten the M29 and G95 coding through hard statements, but am having trouble getting it to switch back to G94 before the next tool. I tried putting in another hard statement with the G94, but it puts it in after the first hole instead of after subsequent holes are tapped. Also having trouble finding where to get the feed switched to pitch.

This is the block for my misc #2 now, just need to find out how to switch back to G94 and feed to pitch.

Since you haven't received any other replies I'll offer this....

 

I can't help with the MP_EZ post, but with the MPMaster post the G95 is set by a switch (see below), so it changes between G95 and G94 automatically.

 

use_pitch : 1 #0 = Use feed for tapping, 1 = Use pitch for tapping

 

If you're hard coding the G95 now you'd probably have to hard code the G94 because the post is not going to know the G95 is there...

add your G94 to the following postline. This is also where you will see the G80 being outout.

Thanks guys, I'll give it a try. Lost track of this one for awhile.
