Each time I process g-code with MadCAM all the rapids are moving at the speed of the cuts which is a lot slower than what my machine can do. I noticed on the post-process screen the message " Rapid Travese not defined in post-processor"

Can someone show me how to edit the post-processor for running permanently rapids of 7000mm/min on X, Y and 2000mm/min on z?

By default, in most of the post processors that coms with the madCAM installer, is using G00 for rapid traverses. G00 will run the machine in the feed that is set in your controller for rapid traverses. This means that the feed for G00 can't be set in madCAM. If you wan't to control the feed with G01 for rapids, this can be done by editing the sections for rapid traverses and replace G00 with G01 and F5000. See example below.

*RAPID*
G01"x""y""z""a" F7000
*END_SECTION*

*RAPID_APPROACH*
G01 "x""y""z""a" F2000
*END_SECTION*

*RAPID_RETRACT*
G01"x""y""z""a" F7000
*END_SECTION*

*APPROACH*
G01"x""y""z""a" F"feedz"
*END_SECTION*

The message " Rapid Travese not defined in post-processor" is just for the time calculation when post processing. You can add rapid feed and tool change time to the post peocessor for a better time calculation. For example:

*RAPID_FEED*
7000
*TOOLCHANGE_TIME*
0.3
