Unexpected motion during a macro.

[cncdrive]

Then I don't know what the problem is. And I also can't figure it out, because I can't read the macro.

Try this on for size:)

Code: Select all

// this macro releases tool from spindle

if(AS3.GetLED(50) == true || AS3.GetLED(51) == true)  // Spindle is still active, so we need to stop here...
{
  MessageBox.Show("The Spindle is still active");
  exec.Stop();
  return;
}
exec.Clroutpin(5,8); // Deactivate resistor
  exec.Wait(1000); // Wait one 1000msec
 
   AS3.Setfield(0,230);     // set b axis dro to zero
 AS3.Validatefield(230);
 
   exec.Code("G01 F100 B-3 M07");        // rotate b axis negative XX turns
   

exec.Setoutpin(5,7);    // lower drawbar slide
  exec.Wait(1000);       // Wait one 1000msec
 

 

 
   exec.Code("G00 B-100");        // rotate b axis negative XX turns
    while(exec.IsMoving()){}

  // End macro

I just ran this in a 100x loop to see what is happening, but only the B axis is moving.
I also looked through the code and I see no problem with it.
I will try to run it a few more times later today to see if I find anything.

Isn't it possible that something else is causing the other axis movement?
I'm thinking of a macroloop or plugin which running in the background and getting triggered to move other axis?

The only macroloop I'm running has to do with tool length offset. No motion at all.

The first time it happened it was the X axis. The second was the Y axis.

The first time it happened was in December and I ran it a lot more than 100 times before it happened again. It's a macro that releases the tool from the spindle. I ran it over 100 times last week alone.

It happened the first time with a UC-300 ETH and the second time with a UC-300 USB.

It has only happened twice.

One other thing. Both times the X and the Y were moving in the same direction as the B. The Macro commands B-. Both the X and Y were moving in a minus direction.
