adding spindle direction to tapping cycle

[Doug Funny]

Greetings All,

I'm trying to add spindle direction to the tapping cycle. On my machine, axial and radial live tools spin in opposite directions. If you don't put the spindle direction on the same line as the canned cycle, it defaults to CW. Everything I've tried so far hasn't worked

Doug sorry, but need a lot more to go on here. What did you changed in the post and where did you change it for starters? Your wording is confusing to me.

You are getting M204 which should be CCW for living tooling but do or don't want M204 for CCW rotation?

Sorry for the confusion. I'm not getting the M204 (or M203) in the canned cycle, I want to add that. This is the section I'm working in. I added g_spdir, spindle_m after pfclampon  on 2 lines

mtap$          #Canned tap cycle, mill
      pdrlcommonb
      if use_pitch = 1, #Feed/Min mode, feed divided by spindle speed is equal to thread lead, changed from 0 to 1
        [
        if rigid_tap, pbld, n$, *sm29, pfspeed, !g_spdir, spindle_m, e$      #Rigid Tapping    Can use G84/G88 with M29 or just G84.2
        pcan1, pbld, n$, *sgdrlref, pgdrlout, pxout, pyout, pzout, pcout,
          pindexdrl, prdrlout, dwell$, pffr, pfclampon, g_spdir, spindle_m, strcantext, e$
          #pindexdrl, prdrlout, dwell$, pffr, [if rigid_tap, "P500"], pfclampon, strcantext, e$
        ]
      else, #Feed/Rev mode, feed is equal to thread lead
        [
        if rigid_tap, pbld, n$, pfspeed, g_spdir, spindle_m, e$  #Rigid Tapping an use G84/G88 with M29 or just G84.2 if rigid_tap, pbld, n$, *sm29, pfspeed, !g_spdir, e$
        if metvals, pitch = n_tap_thds$  # Tap pitch (mm  per thread)
        else, pitch = 1/n_tap_thds$       # Tap pitch (inches per thread)

I got it, I erased g_spdir and added * before spindle_m and it forced the output now
