There is NO easy(simple) way out other than using a good CAM to do the design work then mach will control based on Gcode provided by the CAM.

OR the operator needs to learn to jump through hoops to get the job done.

Or you can create a wizard to do the base code for them.

That is exactly what I want to do. The problem is figuring out what G-code will make Mach follow the feed rate accurately on a rotary axis.

Hi geast1967 greetings from istanbul  I wish you a happy new year
easy solution to your problem
you Rotate Axis  should be  X Axis 
300 X3.14 tube diameter: 942 mm
X-axis stepper resolution /942: X axis step per write
Also!!!
for continuous works  Must be PageWizard or macro

Happy new year to Tekno.
I'm afraid that the solution for my problem is not so easy as you think. If you have red in my first post 
'My question is how to configure mach3 to use either axis A or X depending if i want to cut a hole on a tube surface or just a normal sheet metal X,Y plane.'
So i need both axis X and A. Please be more specific about pagewizard.

You won't be using both A and X at the same time, so just set up both axes and have your CAM output the appropriate code.  A rotary job will use the A axis and a planar job will use the X axis.  With both axes set up on the machine, all the operator has to do is load the material on either the table or the rotary and run the program.

Either of the methods described above will work IF your A axis is fast enough to keep up. MACH will do the feedrate sync IF you set it up to do so.

Hi geast1967 
I did plasma tube cuting machine, I wrote the formula X axis to go 1 tour, because  tube diameter 300mm

for example :300 mm diameter X 3.14 :942 mm X plane You stepdriver 5000 micro step
write X axis  step per 5.370
for test MIDI page    X942 F200 X axis 1tour  rotary

A Axis Not Required because, must be XY Plane work

Page Wizard option: must be For variable diameter

BR549 i try the tube copying tool but i see this toolpath on mach when i load your example.
Can you figure out what is wrong. Can you send me the wright setting for mach in order to see the same picture as you post in the example.[/img][/img]
