Hi Michael You should be able to define the four independent linear axes like you need. You should also be able to use g-code commands like you've written in the example. In the old days, the names and numbers of each axis had to match up -- x 0, y 1, z 2, a 3, b 4, c 5. You may still have to define a z and just not use it.
There are places in the emc where specific relationships between linear and rotary axes are defined but mostly in the interfaces. I don't think you'd see any motion issues the way you want to use it. As a next step, I'd recommend an install of 6.06 from our CDROM on a sacrificial box or as a dual boot. You might be able to download source and install to the rtai kernel you've got running but it may be more trouble than a second install. That done the IRC guys can pretty quickly help with ini setup and testing of the motion stuff you want to try.
