I think Colin was right to begin with about the ref. position NOT being in the NCI. But before I report a bug that might not be there it would be nice for someone with more experience at this than me to confirm that I am interpreting this right. Following is from the NCI file. 1000 (◄ null tool change ) 3557 100 10 1 1 1500 1 -200 -0.008 1 0.22637795 0. 0.1 5. 0. 10. 1 0. 0 0 0.22637795 0. 0.1 1000. 0 1018 1 1 0 1 1 1 0 0 0 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0. 0 0 0 0 0 0 0 (◄ this is the last linear rapid move before next operation?) 0 0.22637795 0. 0.1 1000. 0(◄ should be this right?? 0 0.22637795 0. 1. 1000. 0) 1 0 0.22637795 0. -1.4088 -0.008 3000 1 0 0.505 0. -1.4088 -0.008 300 1019 1 1 0 1 1 1 1041 999 (◄starts next operation) I appreciate all the help!

The ref. position move DOES show up in the backplot though. I have never had a problem with it not being on screen. It works fine in all other toolpaths except a canned cycle??

OK, So I am trying to learn this out as I go. It looks to me in the nci file that at line 315 is code 1000 which is "null tool change" ? right? and at bit 13 of that is "0.1" which is the z rapid position? But I DON'T see a rapid move for my reference position which should be "Z1.0". Am I reading that correctly?

I haven't used that before. Can you tell me what I am looking for? 003557-0020c-PRT.nci

Sorry, that img quality was terrible.

So, if I am reading this right it IS in the NCI data shown at line 242 & 243?

I am using the MPLMASTER post and whenever I use a canned cycle the retract ref. point is missing after the cycle. Here's some sample code for detail.
