Title: A Axis Brake
Post by: Cbyrdtopper on May 18, 2015, 11:33:19 AM

I am wanting to have a brake on my A Axis turn on when it is not moving and off when it is moving.  Is there a way to do this in Mach 3?
I would like for it to have a half second delay also.  So when I hit my keyboard Jog A + button it disables the brake and THEN starts jogging.  When It stops jogging it enables the brake and waits a half second before doing anything else.   ANY THOUGHTS??

The only way you can do it with Mach3 is IF you are only doing indexing the A axis then cut.  You would apply a macro to unlock the brake , wait with dwell THEN move A. Same with stop  Stop motion, call macro to apply brake, wait delay then continue.

Most of that would be controlled from the CAM post or hand coding.




G0 X10 Y10
M100    ( Release Brake, wait 1/2 sec)
A100
code
code
code
A360
M101 (Apply brake, wait 1/2 sec)
G0 X0Y0
etc
etc

Hey  TP
We are doing that on one of our mills already, using a macro to deactivate and activate before and after A moves.  We were redoing a mill with Mach 3 that had Fanuc controls on it.  The Fanuc controller would automatically turn the brake on and off when the A moved, whether you are running code or just hitting the button to jog.  I was just hoping that there was a way to do what fanuc does inside Mach 3.  Thanks for the input though! Greatly appreciated!

Mach3 does NOT have that function.
