Haas C-axis retract

[Rocketmachinist]

I have a problem with the post for my Haas Lathe. The c-axis drilling on Mastercam shows the tool retracting to X-1.1001 in between drilling cycles. The problem is that Haas lathes don't have a traditional G98 clearance plane. G98 in lathe is for feed per minute. So the tool only retracts out of the hole to the R plane. How can I make it cancel the canned cycle retract to the clearance plane and then recall up the canned cycle again?

How do I add the lines in red to my post?

Program each hole as an operation for a quick fix. The Post need to have the 1st part of the drilling copied into the 2nd part of the drilling. In the 2nd part of the drilling you need to force everything to be output.

mdrill$          #Canned drill cycle, mill
      pdrlcommonb
      pcan1, pbld, n$, *sgdrlref, pgdrlout, pxout, pyout, pzout,
        pcout, prdrlout, dwell$, pffr, strcantext, e$
      pcom_movea

Things needs to be copied into mdrill_2$ and some forces processes added. Will need test to see if it covers all the different drilling cycles. If not then each _2$ cycle will need to be changed to mimic what mdrill_2$ is doing as shown here.

mdrill_2$      #Canned drill cycle repeat, mill old method
      pdrlcommonb
      pcan1, pbld, n$, pxout, pyout, pzout, pcout, prdrlout,
      dwell$, pfr, strcantext, e$
      pcom_movea

mdrill_2$      #Canned drill cycle repeat, mill repeat method for canned cycle calls
      pdrlcommonb
      pcan1, pbld, n$, *sgdrlref, pgdrlout, pxout, pyout, pzout, pcout, *prdrlout,
      dwell$, pffr, strcantext, e$
      pcom_movea

Also, in addition to what Ron is doing, you'll want to capture that "Clearance X Value", to be able to force it out, between the moves.

With those Post Block Calls, the 'mdrill$' block is "for the 1st hole" in the series. After you've output the "first hole", all subsequent holes are output through the 'mdrill_2$' Post Block. So, copying that logic from 'mdrill$' to 'mdrill_2$', is what allows you to force out the cycle call and parameters again.
