Rapid to Linear?

[tmorr]

Just starting at a new company and have been using the same post 3 axis milling but getting into 5 axis I was forced to revert to their old bug filled post. There seems to be some major run time increase on my programs. Where before in a scallop or spiral toolpath it would rapid retract then back over the part it will now use linear movements for everything. I don't have a lot of experience editing the post so I'm wondering if anyone has ran into this before and can steer me in the right direction because, I have tried a bunch of different changes with no success.

There is a switch in the control definition for "Convert rapid to maximum feedrate".  Do you have that turned on?  If not, there must be something in the post overriding it.

I believe it is getting overridden. I've changed it in the control definitions, But haven't been able to get what I'm looking for every time I export the g code. It continues to pass over the part at plunge feed rates. Any ideas where to check? My last post was rapiding over the part normally and compared but wasn't able to catch any significant changes. I have made changes to 600 IPM to see if it posts any different but it doesn't seem to. I know I'm not giving you guys much to go on but any guidance would be helpful.

Tmorr,

 

Have you got an answer for this?  I would really like to implement this here also.

Some 5 axis machines using tool center-point compensation will error out if you use G0.
