Normally you set the 4th axis up as the A axis, then for simple rotation you would just command an A movement such a G1 A20 F100

Here are some interesting links.

VcarvePro is the design software I'm using along with Mach3
There are other interesting 4th axis threads on this forum.

I'm in the process of getting my 4th axis
setup. I'm building the motor mount now. Hopefully I will get to do some
testing in a couple of weeks.

Keep us posted on your progress.

It depends on the way you have it configured, cant remember exactly off the top of my head but I think if you have  it as a rotational axis and have rollover enabled you move one way with a positive number and the other with a negative.

Hi, Josh

Hears a little bit of A axis G-code for 8 holes .250 deep, Also has a couple examples of Gear teeth cutting.

It uses some INC G-code and Subroutine Call's, Setting's page, Set A rot. dia. to 2 inch's and zero axes above part. 

Have some fun, Chip

thanks chip I will keep attepting this 4th axis thing
but I also knowtice on the second picture you checked the (use diameter for feedrate) does that always have to be check when using 4th axis rotary.
and on the 3rd picture you checked rotate 360 rollover  does that also always have to be check .
I really dont now what both of those mean If you have some time can yo please explain to me what those 2 boxes are all about.
thanks you.
