Closed loops on the XY positioning stage...
Once I did it the wisdom of his approach in terms of strong connections was obvious. Wish I'd seen that a couple of months ago.
Anyhow, I have both x and y axis positioning stages operating in closed loop mode now. I have a buggy little firmware programme which counts pulses from each axis and turns x and y axis gearmotors accordingly. At least now I have a hardware rig which I can use to work the bugs out of the firmware with. :-)
