    and also my 10 k potentiometers seem to not be linear instead of 12345678910 it seems to be 1 2 4 8 16

    Please detail the rig you intend building, as design Vs physics tradeoffs greatly influence motor choice and placement, tools like SimCalc can help: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    Please be clearer about the issue and what you have or have not done in whatever context, as none of that is clear just yet.

    24V 3A is 75 watts. That’s not enough power to effectively move a rig. Some are more efficient than others but set your sites on 6-10 amps. Often you don’t see torque in the motor spec but if you do think 30-40nM at least if most of the weight of your rig is on a Ujoint.
