Trying to do a retro with Motenc Lite.. and cannot get the pinouts right.. there is avery little info on the site..
Seems they have a common ground. but when applied to the servopakc , the common makes the servos crazy.. ( having major voltage leak. )
any idea..
Thank you kindly..

We would need much more information to be able to help.
Making drives go crazy means you are missing a ground somewhere or miss wiring and all that assuming you are not touching the drive wires with your fingers Something is inducing the 50 or 60 Hz frequency to the drives so they try to rotate at alternate sides 50 or 60 times a second.

They seem fairly clear that they expect you to use www.vitalsystem.com/portal/breakout_board/um7525.pdf
And that you shouldn't need to know which wire it which.
I assume you are not using one of those?

It doesn't seem to have any active components on the board, though.
