Can someone help me with this structure?
I am writing a Plugin for a Baldor Motion control and I am  trying to understand this structure, particularly what variables am I expected to write to?
For example, the variable Enable, is this set by Mach3 or do I set it to indicate that the axis is Enabled?
I have searched the Yahoo groups and the groups here with no luck, I have also looked at the customization WIKI.

Thanks,
Craig Deady

craig,

   what are you trying to do?

When you say Baldor Motor controller do you mean Spindle motor controller?

If so, what kind of stuff are you trying to do with the control?

Alot of control options can be done through a modbus connection to your MC.

Scott,

Not Baldor MOTOR control, but Baldor MOTION control. It is a multi-axis motion controller that can control up to 16 axes of servos and steppers. The servos can be local to the control (analog type drives) or network based drives (using Ethernet powerlink). So, in my case the Baldor Motion control will control all axes on the machine as well as the I/O (inputs and outputs). Thus the Plugin will be a movement plugin.

Craig

Ahhh,

    Well then you would need to find out, the format that it will take for executing Motion commands.  (see the Galil plug in example for instance).  You will need to get into the documentation, to see what kinda instruction set the control will take to preform its movements.

Scott,
I don't need help with the Baldor interface, I know that.
My question was to get information on the AxisInfo structure that is in Engine.h and what the variables do, which ones do I write to from my plugin and which ones are written to by Mach.

Craig

The engine variables in the Axis structure are for the Printer Driver, if you are doing an external motion board then you will have to do something else, as I was trying to tell you above. But here is the stuct with my understanding of it, some of it I am unsure of cause I dont use alot of it.

struct AxisInfo
{
    int   Index;    // Current Count
   int   MasterIndex;  //Machine 0
   char  StepPin; // Pin for step pulse
   char  DirPin;  // Pin for Direction Pulse
   char  StepPort; // Port # for step
   char  DirPort;  // Port # for Direction
   bool  StepNegate;   // low active step?
   bool  DirNegate;    // low active Direction?
   int   CurVelocity;  // Current Velocity
   int   MaxVelocity;  // Current Max Velocity (jogging )
   int   MasterVelocity; // Master Velocity...Maximum Velocity in all circumstances.
   int   Acceleration; // Acceleration
   bool  AtSpeed;      // At Speed Currently
   bool  Acc;          // Accelerating?
   bool  Dec;          // Decelerating?
   bool  Enable;       // Axis Enabled?
   bool  Jogging;      // Jogging On?
   int   JoggDir;       // Direction of Jog;
   bool  Homing;       // is this a homing jog?
   bool  DeRef;        // Dereferanceing Move?
   int   Memory[6]; //dont know
   int   ActiveMemory; //dont know
   int   Color; //dont know
   int   TripCount; //dont know
   int   DepthCount;  //dont know
   bool  Probing;
   bool  Slave; //is this axis a slave
   int   SlaveAxis; //what axis is it slaved to
};

Scott,
Thanks for taking the time to help me with this.
