I am trying to use a Y axis DRO to trigger clamps to release. What I would like is to watch the DRO, and when it is between 10 and 20 inches from Z, to release an air cylinder (over ModIO). I have control of the cylinder in a different brain.
I set up a brain that uses the Y axis DRO, then a >10, then a <20, then a NOP, then the modio address. When I watch it and move the axis, the DRO value doesn't change.
Any thoughts?
