Sorry not sure what you mean about the Airtec.
So just doing some early thinking about this. First convert to inches being your machine units. You said you have 8 vents and the table is 144 inches long and 72 inches wide.
So let there be 8 zones numbered 0 to 7 with 0 in the front left and 7 at the rear right.
We can make an array of hal pins to agree with this structure
The zone boundaries on the Y axis will be at 36", 72" and 108"
The zone boundary on the X axis will be at 36"
We can also set an array of pins to set there pins in you hal files using setp.
We need to convert a position to a zone.
The X axis is easy
Code:
int xzone = (axis.x.pos-cmd < 36) ? 0:1;
The Y axis is a bit trickier
Code:
int yzone;
if(axis.y.pos-cmd < 36)
yzone = 0;
else if(axis.y.pos-cmd < 72)
yzone = 2;
else if(axis.y.pos-cmd < 108)
yzone = 4;
else
yzone = 6;
so now we need to resolve the zone number
Code:
int thezone = xzone+ yzone;
So now its time to set the pins
Code:
int i;
for( i = 0, i < 7, i++){
pin[i] = (i == thezone)? 1:0;
So there are probably a few typos above
I think the logic is right, I just have to flesh it out into a component another time.
