Hi Steve

A while statement loops the statement (or block) after it not before it. See:
https://msdn.microsoft.com/en-us/library/y1tscb5y.aspx

Avoid placing a Move statement inside a loop. It should only be commanded once to compute and launch the motion trajectory.

ch2->Position (case sensitivity is important) is the measured encoder position. If you don't have encoders on your system then Position will always read zero. For an open loop system use the commanded Destination ch2->Dest instead.

Try something like:

#include "KMotionDef.h"

main()
{
    double steps=10000.0, vel=1000.0, setpos=5000.0;

    MoveAtVel(2,0.0, vel); // move to a known position first
    while(!CheckDone(2)) ; // loop doing nothing until motion is complete

    MoveAtVel(2,steps, vel); // start the move

    while(!CheckDone(2)) // loop until motion is complete
    {
        if(ch2->Dest > setpos) // Dest passed setpos ?
        {
            SetBit(45); // yes set a bit
        }
    } // end of while loop
}

I tried to read the position using this:

{

pos = ch2->position;

if(pos

> setpos)

{

SetBit(45);

}

MoveAtVel(2,steps, vel);

}while(!CheckDone(2));

I am attempting to fire and output while an axis is in motion and it passes a set position.

Currently I am using the following to make my move:

{

MoveAtVel(2, steps, vel);

}while(!CheckDone(2));

I tried to read the position using this:

{

pos = ch2->position;

if(pos > setpos)

{

SetBit(45);

}

MoveAtVel(2,steps, vel);

}while(!CheckDone(2));

but pos always shows 0.

I know I am total doing something wrong. (It's late and been a long day.)

Is there an example I can look at or snippit of code someone can show me?
