Re: What is the best place to mount CIM motors...?

REMEMBER! Placing a motor is not just a mechanical consideration!

If you will be using encoders on your drivetrain, be wary of scary electro-magnetic fields created by motors and high currents. Especially if you are using analog encoders (aka limitless potentiometers) keep your motors and their wires as well separated as possible from the motors, and remember to use shielded cable for sensors in high emf areas.

cat5 is unshielded twisted pair, but yeah, take care with the wiring!

Re: What is the best place to mount CIM motors...?

I bought a 4 1000 foot spools of Plenum Cat6 shielded cable (my family recently built a second house, that has almost a mile of Cat6 in it.... minimum of 2 home runs per room, including the bathrooms )

I have about 300 feet left over, so that should be plenty for us. It's beautiful how each pair is separated by plastic.

It also makes things nicer when you build this to keep in mind robot up keep. It may look easy to maintain when you don't have your arm or whatever this years manipulator will be on there but once you cover it things become alot more interesting in the long run when something malfunctions and you need to fix it.
