Subject: Slaved Axis

Tom,

I recently talked a friend into buying a Kflop and Kstep for his CNC with the understanding that I would help him get it running.  (Blind leading the blind).  His machine has a master/slave Y axis.  When I jog the Y axis both steppers turn but then the slave stepper pauses and turns again.  When I go to the Step Response screen and do a move, both motors seem to work correctly.  What am I doing wrong?


Also, the Z axis stepper won't move.  Is the EnableAxisDest set correctly?  If I move the stepper to the Y axis it moves.


Attached is a copy of my Init File.

Hi Jack,

Very simple :-)

If you read through the code you are enabling Axis 1 twice but not Axis 2.  See your calls:

    EnableAxisDest(0,0);
    EnableAxisDest(1,0);
    EnableAxisDest(1,0);
    EnableAxisDest(2,0);

I believe Axis 3 is your Z axis (Axis 2 is a Slave).  So include the Z axis in the coordinate system not the slave.

Change:

    DefineCoordSystem(0,1,2,-1);

to:

    DefineCoordSystem(0,1,3,-1);

Thanks Tom,

As usual, your suggestions worked perfectly.  Thanks.
