Thanks for your previous help, it was absolutely invaluable for this post and many to come.

My tweaked post for the ProtoTrak DPM works like a champ now with one exception and that is that a null tool change never seems to get called (the ptlchg0 section of the post never gets used). Where there should be a null tool change the the post uses the ptlchg section. Is this something that needs to be changed in the post or is it a MasterCam setting that I have overlooked?

In some posts the ptlchg0 calls ptlchg
Example

ptlchg0
ptlchg

Copy and paste your ptlchg0 into a message.
