Resolved by EzAng!
I have an ezb v4 that has been on the shelf for several years. (worked when last used). I was on the shelf too so we are both a little dusty so bare with me. When I set up an I/O port in ARC for a servo there is no signal present on the signal pins. I have a scope on them. If i go to the diagnostics page of the ezb's web server and hit the "center all servos" button the pins come to life. I think its something simple but ...?

First, Did you download the latest software?
I have tried ARC beta on a older machine running 7 and the latest ARC on a win 10 machine both behaved the same.
both behaved the same?
make sure your anti virus is off or turned down to connect
ARC / ARC will not connect with the anti virus
Yeah they both act the same. And they both can communicate with the ezb just fine. The camera works on both as well. I disabled defender firewall rules on the win 10 machine...no joy!
So, if I got you straight, they both can communicate with the ezb 4 just fine. The camera works on both as well.
just the servos don't connect?
Is the polarity correct when you plug in a servo to a port? like ports D0 to D23
ground - brown / blk vcc - red signal - orange / yellow

Camera Works But No servo Movement
We assembled the jd robot exactly as in the instructions, including servo alignment. When we turn it on, the camera works but there is no servo twitch. No actions from the app are executed. How can we figure out what is wrong?
please let me know if any of this helps thanks
I can plug the servo in and power up the unit and the servo will "twitch" it is not one of the new digital servos. When the servo didn't work, i broke out the o-scope and tried several i/Os and none of them showed any pulses until i went into the diagnostic page on ezb,s web server page and clicked on the button that says "Center All Servos" at that point I get the pulses on the scope that i would expect. If nobody knows what is wrong, my next try will be a script directly into the command line.
none of those linkes helped?
then Sounds like a question for DJ when he shows up again
good luck
I really appreciate your time. Thankyou!
