Hello. Last time I used a k analog board which had all the screw break outs but this time I'm doing a kflop with snap amps
So what is the best way to do breakout connections to the 50pin on the snaps. And the 26,16 or 14 pin connections on the k
I figure a ribbon cable to a breakout board but wanted to avoid making antennas for pickup of noise
What do others use these days? Thanks

Hello,
I used a 50 pin ribbon to screw terminal breakout board for my I/O and encoder input with no trouble. My 50 pin ribbon cable length was only about 8 inches. The non isolated I/O signals went to opto isolators on other boards and mine had wires on them about 1 foot long from the breakout screw terminals to the terminals on the opto iso boards. I did add a .005 mfd cap across each the opto LEDs and across the opto output connections to cure some failures I was experiencing on the output optos. I attributed the damaged opto couplers to the PWM noise from the Snap Amp but I didn't really science it out. I just the caps across the optos and the problem disappeared.
Good Luck,
AZ

Hello,
Winford.com is a source for simple ribbon cable breakout boards such as:

As always try to keep the ribbon cables as short as possible. Ideally only several inches.

I always forget about Winford. But ended up buying some assortments of pololu plugs and connectors. I've used them before so hopefully will work ok. Have high hopes for this setup with the k and snaps. For machine 2 I built using the k and analog with the moog drives is very impressive and done thousands of parts with it. Can't wait to have machine 3 fully up with the snaps. Have expectations for a super smooth fast accurate machine
