CYCLES AND RETRACT MODE G98/G99 ON HAAS MACHINE

Hello !

I have a problem with G98 and G99 on HAAS machine. For correct function of G98 and G99 I have to specify in Post Builder that the drilling cycles do not fall apart. As it is defined in Figure 1, it is correct when using G98.
If I enter Non Cutting Moves on the Transfer / Rapid tab in Between Features DIRECT, postprocessing generate the cycle G99. It is OK.
Why does the postprocessor generate a cycle like G81 at the last hole ??
This is wrong because even if G98 is selected, the tool moves me to the "R" value and not to the starting position.
If G98 is in conjunction with G81, the tool moves to the last known position, which is "R" when G98 is used up to G99.
Please advise how I set up in PostBuilder so that cycle G81 does not repeat at the last hole or when changing G98 or G99 ??

Thanks for your advise !

Assuming Holemaking and not PTP?

I think there is only "MOM_force once G_motion" hidden somewhere.

And also think it is designed to work like that.

The solution is to insert a "custom command" into the Cycle parameters "MOM_disable_address G_motion" and when cycle off the "MOM_enable_address G_motion"

 

So far, it works as it should.

Thank you,

 

Yes, "MOM_force once G_motion"  works. In my case, I used this to hide the G84, because we had to create a deep-threaded cycle ...
