Odd times in backplot

[rdshear]

What would cause the estimated time to be out of whack. I'm running X2 MR2 Lathe. The post is a custom post I have been working on. The times seemed to come out somewhat normal in X MR2. The calculated rapd time seems correct, however the feed time is way off and then the total is less than the rapid + feed times? See the picture below. Note the distance travelled in feed and rapid vs. the times.

 

Could my post do this? The machine Definition?

 

I have the feedrates set in the general machine parameters of the machine definition.

 

I'm not sure where to look exactly as I don't know what would have changed between X MR2 and X2 MR2.

 

TIA,

Ok, I just checked a file in X MR2 and it is goofy too. If my feed is set in fpr I get odd numbers if I change it to ipm, the times seem correct. I'm assuming something in the post is doing this. Am I correct?? I didn't realize the post would affect backplot numbers.

Bump:

 

Can anyone steer me in the right direction?

 

TIA,

Are you by any chance running CCS?

If you mean CSS, then yes. Even though the control I made the post for is a mill control on a lathe and doesn't support CSS, I use that value in the post to calculate the spindle RPM at the diameter of the first cut.
