Hello team,

 

In order to maintain a clean look at the robots base I am thinking of utilizing some of the unused wires in the keystone jacks. It seems like the CAT6 cable can handle between 1.2-2.2 amps max (depending on your googles) and the DS3225 stalls at 1.9-2.3A (kind of within spec? - hopefully I wont be stalling often or for long periods of time).

-Is this a terrible idea?

 

My question is would it be ok to split the power/signal/ground wires between 2 CAT6 cables?

Would it matter which way I would do that? For example:

Center Jack pin 7: GND

Right Jack pin 7: +5V

Right Jack pin 8: Signal

 

Or

 

Center Jack pin 7: +5V

Right Jack pin 7: +Signal

Right Jack pin 8: GND

 

etc...

 

The other option is to route the wires out of the pneumatic hole and try and add some strain relief

 

Appreciate the help!

Cheers,

Johann

Hard to say for sure in your case, but I had to run my servo gripper in its own shielded cable for a clean signal, otherwise the servo would twitch.

@dedoky

Interesting. Did you run the shielded cable all the way from the robot gripper back down to the main electronics housing?

 

How long is your cable?

 

My CAT6 cables are shielded so maybe I just need ~1m length of wire going from robot base to the gripper

I ran the wire from the main electrical box all the way to the servo.

@dedoky I have my robot on a 1 meter long track so I am trying to avoid any additional wires going up the arm that aren't going through the base box
