Chamfer error Mapps control

[pasman]

We just brought this Mori Seiki CL 203 with MAPPS control out of moth balls.
We have attempted to turn OD threads.
The program steps through in single line fason OK.
We continue to get a "Chamfer error" when we attempt to run in auto.
We think the problem has to do with the G92 that the MAPPS generates but we have not been successful at resolving the error.
Does anyone have a suggestion where we might start to resolve the problem.

Thanks in advance,

Phil

I thought I added this code earlier

Try putting the M24 on the G92 line.
