Hi,
i use the shuttle pro about 2 years. Never had any problems with the middle position. Always stops when I release the wheel.

Hi Nixie,
in members docs section you find the topic  "spindle speed control"
within that a pdf file that may help you.
btw thanks to GhrisJ for posting it. Was a great help for me.

Hi Dan,
when I look at your workpiece it looks to me as your code does more or less what it should do, but your tool has not the right shape.
See pict.
just a thought

When your A axis rotated 10 times then there should be 3600 degree.
The feedrate in your code depends on your cam settings.

Only when I turn off all the rotation options I see a decent preview screen but high A axis values.
The A axis value that you see is the actual position of the axis in your active work offset ( eg. G54) without cutting the value above 360
when you have a value of let's say 1079 degree, and you check then " Rot 360 rollover " then you see 359 degree but Mach remember the 720 degree (which are cut)
when you uncheck  " Rot 360 rollover "

Hi,
when the code is really correct until the "Y0. A-0." I guess there is a issue in the post processor.
Try using a fanuc PP.
just a thought
Is your A axis turning the same direction as in Mastercam?
Is there any G91 in your code?

Hi archcomp,
Mach needs a index  pulse that is at least 50% wider than the other pulses. Mach is watching that  pulse to start the threading.
I guess your encoder don't provide that wider  pulse.
just a thought.

Hi Max,
if you want an angle greater then 360 degree then UNCHECK the " ROT 360 rollover " and " Ang Short Rot on G0"
in General Config menu.  ;)
