Halt and resume GCodes

[IvanSiberia]

When a custom G code like MoveAtVel(AXIS_Y,(coordinate)*10000,speed*10000/60 ); is executed in KMotionCNC ; . When you press the F5 button, the interpreter window sometimes pops up with the loss of the trajectory. How to pause code execution correctly?

Hi Ivan,

Did you mean a Custom MCode that executes a C Program to make a Move?

If after the Move the Code waits until the motion is completed then executes a Halt next line such as this:

Code: Select all

#include "KMotionDef.h"
#define TMP 10
#include "C:\PerforNext\CNC\User\C Programs\KflopToKMotionCNCFunctions.c"

void main()
{
	MoveRel(0,10000);
	while (!CheckDone(0));
	DoPC(PC_COMM_HALT_NEXT_LINE);
}

And the MCode is configured to Exec/wait/sync then the Interpreter should be synchronized with the new position and be able to resume cleanly.

My code will execute on command M 104, I want the operator to be able to stop the code and continue without popup.

I'm not sure what you mean by "I want the operator to be able to stop the code".

But the example I gave should stop and allow a resume without the popup.

M104 exec/wait/sync

Code: Select all

#include "KMotionDef.h"
#include "Mikromat InputOutput.h"
void main()
{

	MoveAtVel(2, -1000, 1000 * 1000 / 60);
	while (!CheckDone(2));

}

M107 exec/wait/sync

Code: Select all

#include "KMotionDef.h"
#include "Mikromat InputOutput.h"
void main()
{

	MoveAtVel(2, 0, 1000 * 1000 / 60);
	while (!CheckDone(2));

}

Hi Ivan,

Ah, I didn't realize you were randomly hitting Halt.

I'm not sure how you expect that to work, if you have a C Program that is supposed to do something and you Halt it part way through then KMotionCNC doesn't have a way to resume the C Program part way through. So it asks is if it ok to re-execute the C Program from the beginning after doing these things.

Maybe you could explain your application in detail and what are you trying to do.

You could probably create a new "Halt" button that would wait until the C Program finishes and then Halt.
