Hmmmm, can't get it. I have formula set to (1000). So it's OEMTrigger14-Formula (1000)-OEMDRO:817. Feed is set to 1000 when Mach 3 starts, but button does nothing.
There is no OEMDRO 817 in pulldown, and type in box says 1000-2255 valid, but checking and typing 817 gets above behavior.
And.....is the formula simply set to 1000, (1000), or a=1000, or something else? (1000) makes it set 1000 on Mach startup, so OEMDRO:817 must be good! Maybe 1000 does that, too, don't remember. a=1000 doesn't do anything.
Attached the brain, it's the bottom button, OEMTrigger 14 so it's easy to edit without having to redo the whole brain.
