Anyway, I incorporated this in my custom-postgui.hal, but made it for 4
axis's since I have a rotary table usually bolted on as A, and all those
additions show up nicely in the hal configuration display, including the
proper position data when I "move" all 4 with motor power off (all
steppers)
But there is no dro display over the camview window.
Advice?
Cheers, Gene
