Save your macro in the macro folder of your profile and call it with M1083 in your code

The secret with Mach3 turn is to long code everything, cycles do not work like in mill

I take it you have a speed sensor on the spindle.  If not you can not do feed per rev only feed per minute.

Try it like this :-

You could try the 'Ref All Home' button on the program screen.

Are you sure the a axis is rotating in the right direction and at the correct distance.

To check the rotation place a hex head bolt or a piece of hex bar end in the chuck and set a flat square with a clock or a square block.

Then enter and run this program :-

%
G92 A0
G91
G00 A60.
M30
%

The A axis should roll the top of the chuck toward you for 60 degrees and the next flat should be square to your original flat.

A sample of the code you are using may help

I think the 540 defaults to 10 micro steps which would give 2000 steps on a standard 200 step motor.

I am not sure all the % signs in the program are a good thing especially as there is an odd number of them and they work in pairs normally.

They are normally to indicate the start and end of the program.

Just a thought

Lets see if the old grey matter is still working.

It is best to set your steps for a 1 degree movement so if you need to move 72 motor revs per 360 degrees then its 72 X 200 steps (or what ever your steps per 1 rev of the motor) divided by 360 this is your steps per 1 degree which would be 40

If you turn off 'roll over' and 'short path' then you can command A720.0 or A1440.0 and it knows its to do and done 2 revs or 4 revs of the axis, it will also do 2 or 4 revs back if you command A0

It could be an old lathe command that is now defunct.

Are you using the free version of Fusion, from memory its not 5 axis only the Pro version is.
