Tom:
Very close. I am simply trying to come to grips on the best avenue for it.
For example, I could program in an index pulse when the X axis has moved a
particular number of steps or is on a numbered step boundry, for example,
pulse whenever X is on a multiple of "x"mm's. This would create a sampled
grid.
In a buffered controller, there are limitations on the ways this can be
done. I cannot do, for example, multiplication or division in the Ring0
code. It is not permitted. SO I have to pre-plan the pulseing methods based
on integer arithmetic and I have to do it in real-time. I can get around
this somewhat by codeing the index pulses into the buffered stream, but even
then I have to have a way to devise if its time for the pulse and a way to
give you as much control as possible over the pulseing interval.
Any idea's you have are welcome. The work I am doing presently would allow
me to get it done almost right away.
