Thanks for the help.
Marc Lindsey over at the eMasterCam Forum explained the use of axis substitution and this worked perfect. It replaced the Y moves with A moves. I wasn't sure if this was going to work, so I tried it out on some scrap and it worked great. The only thing I had to change in the post was to switch the 4 Axis button on.
The more I learn about MC, the better it gets.
Later....
