Program stops at this line, any ideas?

[mmurray70]

Hi guys running some parts today and everything is running fine for several tools and then suddenly stops right after a toolchange and just does nothing. Buttons are still greyed out as if its running, but it just doesnt run the next line. If i halt and restart on that line it runs fine. Any ideas? Here is the code:

Its stopping on line 2790. I included the code from previous tool, format is basically identical and that runs fine?? Stops in the same place every part.

Looks like the problem was with my machine and not with Kmotion. My high range tensioner wasnt retracting all the way after going into low range. And my M3 program was just sitting there waiting for the conformation signal.

I should probably add some time limits and error messages to these while loops. Anybody know if theres an example program already done on displaying an error if in a while loop for a certain period of time? Something that could be easily added to this code that caused the problem on my machine:

if (!ReadBit(154) && ReadBit(156) && (spd <= 2300)) // stopped, in high range and s less than or equal to 2300
	{
		ClearBit(156); // disengage high
		SetBit(157); // engage low
		while (!ReadBit(1041)) // wait for high idler home signal
		{
		WaitNextTimeSlice();
		}
		SetBit(154); // spindle on cw
		SetBit(159); // Turn on air seal
	}

You might try an approach like this:

include "KMotionDef.h"
#define TMP 10 // which spare persist to use to transfer data
#include "KflopToKMotionCNCFunctions.c"

main()
{
    double TF = Time_sec() + 3;  // timeout in 3 seconds

    while (ReadBit(46))  // wait for something to happen
    {
        if (Time_sec() > TF)  // Timed out?
        {
            if (MsgBox("Tool Change Timeout.  Halt?", MB_YESNO | MB_ICONEXCLAMATION) == IDYES)
            {
                DoPC(PC_COMM_HALT);
                return 0;  //exit program
            }
            else
            {
                TF = Time_sec() + 3;  // continue and timeout after 3 seconds
            }
        }
    }
}

That code works perfectly Tom. Still running machine with the tensioner problem till i get this job done and now it tells me exactly whats wrong. Thanks.
