Feed not in G code of contour opp

I did a rough op followed by a countour pass. The Feed rate set in the contour was 1600.
But the G code did not have the feed rate in the code at the begining. So UGS errored out
and said Ididn’t have the feed set. So I added an F1600 in the code just before the G0 and it ran fine. The roughing had the feed st in the code. I moved to Ver4.1 and tried again with the same results.
So in countour I can’t get feed rate to be at the start.

can you share the workspace (files → export)? I’ll try to replicate independently

The KMZ file is 8MB and there is a 4 MB limit on the forum. Can I email it to you?

of course [ sa at grid dot space ]

Just got it sent,
Thanks,
