Post G43 between index moves

[BNFab]

So more post trouble... the post wants to output a safe index (g91 g28 z0) between paths... Ok I am fine with that at this point, but it doesnt recall the tool offset... How can I add this between index's so after the offset is called for the next rotation it will post my tool length comp?

 

 Thanks

It's really going to depend on the post you are using and how it is set up to do this....

 

But I would start looking the in the ppos_cax_lin section

[BNFab]

I dont know what section that is? Can I do something like this? 

 

pfzout                  #Force Z axis output

      *sgtlng_on, *tlngno$

      if absinc$ = 0, *zabs, !zinc

      else, *zinc, !zabs , 

      ms_z = zabs

 

I added the first line , *sgtlng_on, *tlngno$ it seems to work..

Except for the initial call, it double posts the g43,    .

Ok I dug a bit more, and I found a "Null tool change logic" segment under ' papproach0 '

 

If I insert my tool length setting on , and all that it seems to post correctly... Hopefully this works and only affects this area..

Disregard this post

G43 is modal. So even if your machine homes between rotations your length offset will not cancel until you cancel it or call another H offset.
