Hi All
I joined the forum after completing the cnc conversion on my X3 when I converted it I made provision for a fourth axis which I have now installed Mach 3 sees it ok but when I used the gear cutting NFS wizard x and y do what they are supposed to do but A axis does not respond. Any Ideas?

OK,
What happens if you type this code into MDI
G00 G90 A90.
put a sample of your code here for me to look at.

Hi
On running you code the A axis moves for about half a complete turn of the table. Here is the code I am trying to run
G00 G64 A0.0
Y-30.1 X0
(This program has No Z moves!)
M98 (Index.tap) Q20
M5 M9
M30
Cheers

OK, I would have expected it to just move 1/4 turn.
The code you have shown may need a tweak
G00 G90 A0.0
Y-30.1 X0
(This program has No Z moves!)
M98 (Index.tap) L20
M5 M9
M30
Try it like this and let me know how it has changed

Hi
We seem to be getting there your code worked fine with the rotary table moving the correct amount so
I tried running the NFS wizard to cut a 30mm dia wheel blank with 20 teeth it spends 4 minutes cutting the first tooth the at the end rotates 18 deg and starts again on the next tooth I would have expected it to cut one tooth then rotate to the next one but I could be wrong.
cheers

Good, thing are working.
I would post your NFS problems in the NFS area an may be Ron Ginger will answer you, Ron maintains the wizards so he should know the ins and outs.
