https://forums.autodesk.com/t5/hsm-post-processor-forum/bar-puller-positioning/m-p/6084857#M27036 so, I figured out my pcode error. I removed the automatic numbering from HSM edit and have the post processor spit out an N number instead of an O number.<BR /><BR />It looks like we don't have macros available (at least according to the instructions here: http://diy.haascnc.com/presentations/use-macro-variables-make-parts-counter )<BR /><BR />Looks like tomorrow, I'll take a stab at the material change code. I can use your outline above as a reference. Again, I appreciate the feedback Greg. <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span> Wed, 22 Jul 2015 22:37:16 GMT mfeathers 2015-07-22T22:37:16Z
