Hi Noel,

Do you have the M6 Action set to Execute/wait/Sync? If not try that.
Hi Tom

the ATC action is working now, i was missing "Execute/wait/Sync" Thank you very much.

Hi Tom

I am working with an ATC carousel and my C.program is working ok exept one thing, regarding to slot number match. let s say that the program execute tool change ok, it does select tool number ok and get back and put the tool in the fork, raise spindle, carousel rotates and select the next tool everything ok to this point. my issue is when i rotates the carousel manually when i need to replace tools or set newones, the program does not make the carousel comeback where the last tool was grabed for the spindle, so it keeps on the position randomly i rotated and of corse it will crash the tool in the spindle.

Hi Noel,

UnloadTool is defined as

Code: Select all

int UnloadTool(int CurrentTool);
and

Code: Select all

int UnloadTool(int CurrentTool, int Tool)
Please make them consistent. Compiling with the TI Compiler will provide warnings of this.

This code

Code: Select all

	if (CarouselPosition(), (Tool))	// need to load different tool?
seems wrong. In C multiple expressions separated by commas return the last expression. See here.

Probably should be:

Code: Select all

	if (CarouselPosition() != Tool)	// need to load different tool?
Similarly with:

Code: Select all

		while (CarouselPosition(), (Tool))	//when carousel find the requested tool
HTH

Hi Tom

Thank you for your help.
My ATC program is working, it returns to last tool position without crashing tools.
now I have an other problem, my ATC carousel uses binary code sensors to select each tool, there are three sensors aligned under the aluminum plate with steel pins to code each tool. and there is one more sensor on the shaft of the motor, i used that for tool number 8,everything works fine exept some tool numbers fails the rotation, depend where is it, I found that when the carousel try to rotate, in some point it clears the rightmost sensor first than the middle one, then the middleone clears first than the leftmost sensor this is ovious for the rotation angle, but the ATC C.program read that changes right away and make the carousel stop before it reach the next postion, so the tool would crash, this is only when the carousel try to start to rotate, it moves just few degrees and stop, and not fails in all positions mostly it works fine, for example from tool 5 to 4, 6 to 4, 7 to 4, 7 to 6 it fails, all depends if the rightmost sensor involves code.
is there some way to disable the sensors for some miliseconds when carousel start to rotate then enable them to catch the next position, or make some code to read first the three sensors clear then read the code, that way when the carousel start rotating ignors sensors until they clear and get new code, i dont know if i axplained well?.
this is my atc C. program

regards.

You might wrap the CarouselPosition function with a function like CarouselPositionStable that detects whenever the position changes and records the time. Then return position invalid (-1) until it has not changed for a certain amount of time. Then return the CarouselPosition.

Sounds difficult for me, could you give me an example please, i have not idea how to record the time

Try this:

Code: Select all

// return Carosel Position when stable otherwise return invalid (-1)
int CarouselPositionStable(void)
{
	static int LastReadPosition=-1;
	static double LastChangeTime=0;
	int NewReadPosition;
	
	NewReadPosition = CarouselPosition(); //read sensors 
	
	if (NewReadPosition != LastReadPosition)  // changed?
	{
		LastChangeTime= Time_sec();  // record when
		LastReadPosition = NewReadPosition;
	}
	else
	{
		if (Time_sec() > LastChangeTime + 0.2) // no changes for a period of time?
			return NewReadPosition;  // return stable reading
	}
	return -1; // not stable return invalid
}
Note the UnloadTool inconsistency has not been fixed which will now probably become important. Currently the parameter 'Tool" is being used but never set by the caller so is basically garbage, so most likely doesn't match the CurrentTool, so always decides it must rotate the Carousel, but then instantly sees the Carousel in position and stops rotating.

i made changes for this and TI compiler does not show warnings any more, i know something is not correct, the carousel still detecting wrong reading in some tool numbers.

The code is still calling CarouselPosition. CarouselPositionStable is never used.

Hi Tom

My carousel is woking great now, i finally make the code you sent me work exelent.

Now I am dealing with tool length offsets, i have not understood some points, because once i set some value in the table tool, everytime i reset home with different tools loaded looks like it chages the height from the reference point to machines bed wich is the the zero point.
this is the secuence.
when i turn the machine on, first thing i do is reset home, so the axis move slow to find the sensor then comeback few inches away then set X and Y to zero.
the Z axis go down few inches then sets automatically 3.875 inches , i write that in the home reset c. program.
each tool go down to cut from that point, i entered a lengh value for each one in the tool table, but i have noted that if i rest home with different tools loaded in the spindle, the heights change respect to the machines bed, so they will cut too deep or less deep, there is my g code attached.
