Centroid Acorn Controller - Has anyone tried one?

[JAZZCNC]

Chaz been doing little digging and looks like the acorn is setup in such away that it watches inputs to determine where the turret is located.
This is why the Orac code is so simple. The PLC is watching the I/O to determine which turret location currently at then moving to new location.

There isn't any code in the PLC like what your probably thinking. All the PLC does is watch 3 inputs and depending on there logic state knows turret location. ie:
In1=on In2=off in3=on == Turret Position#1
In1=on In2=on In3=off == Turret Position #2
In1=off In2=on In3=on == Turret Position #3
And so on for each Turret location.

Using this Logic indexing it rotates the turret while watching the I/O untill matches tool # taken from G-code and stored in parameter #4102 and when finished returns sets this location in Memory and sets parammeter #90014.
This Logic is the only thing in the PLC which can be changed.

It should be possible to change the PLC but this is beyond me at the minute.
However think we could easily work around this and effectively do it manually using the Macro with simple moves then set the parameters to keep track where located.

Also note Centroid don't use G91 incremental moves. If want to program incremental move you use UVW moves ie: x10 Z-5 would be absolute moves.
incremental moves would be U10 W-5.

What axis would you use for turret.?
