Doug,
I was looking at the whole arangement last night. As I fiddle with the set
up more and more, there is less and less of the original microkinetics stuff
left. I figured I have come this far, I'm gonna redo the signal versus power
layout. I ordered a perforated metal cover to house the three power supplies.
I think the filtering caps are too small but otherwise the PS's are OK. I'm
gonna find or build a separate +5 volt supply for the opto's. I will thus not
use any of the "logic" power supply outputs anymore. The computer connection
was removed from the back panel along with the long leads to the indicators
and solid state relays. I'll route the signal lines up and over the new cage
over the existing power supplies. I ordered the factory cages for the Applied
Motion Products drivers also. I'm not gonna leave any stones unturned. I'll
send pictures to you if it goes well. I hope to have most of the work done by
tomorrow. The cage is being made today, the drive cages are being sent to me.
It's a bummer to have the signal lines come in from the front, particularly
the limit switches but I want to see if it works first. If it does, I'll
refine it from there.
