    so you tell me that i must coonect the wire from psu to the bridge rectifier and from the bridge rectifier to the motor right?

    Correct

    You will likely need to use some form of back EMF protection no matter what PSU you use. It's a really simple and cheap circuit and is definitely worthwhile.

    I would recommend getting one of the high current switch mode power supplies.
    As a rough guide check what the controller motor output protection (fuese,overloads etc) are rated at and use this figure together for each channel. Somewhere between 20A to 40A
    I would then measure your load using a multi meter or current meter when the motors peak with fast movement - you may or may not be able to view the peak current (depending on the meter read speed) but this should at least give you a ball park figure. Or if you know the motor rating (watts) you can calculate it out.

    In addition to the PSU it looks to me that you also have a design problem.

    A lever is most effective when at 90 degrees to the rod, with around 38-40 degrees either side of that about the maximum range before use of effective torque drops off dramatically.

    In the video you have a compact full frame design, which needs lots of torque, small wiper motors of likely limited power and the lever looks to almost be aligned with the rod, where it is pretty much ineffectual:

    use a car battery as a buffer to the motor - it takes the spikes and regenerative voltages away from the power supply

    I use those motors on my compact rig, but with 60:1 wormdrives for greater torque.

    The standard 25:1s can operate for light loads in a compact design, but will be working pretty hard.

    Hi..

    My motor potentmeter move the other motor...like when i turn left potenmeter the left motor turn but while the motor moving the right motor move a little why?!

    i checked all wires and all thing is good why the other motor move?

    and both motor potentmeter when i move them a little there is no movement like there is a deadzone why?
    the potentmeter is new and replace them but nothing changed help!?

    + i set simtools axis for nolimts2, when i use simtools test the motor move in a place that i want.. but when i start the game and the rollercoaster move the motor move more than what its must move in why? does the top problem related to this one?

    Before messing with NL2 can you please confirm that the rig behaves as expected in both SMC3 and SimTools Output Testing.

    In smc3 the motor not going up in realtime like it has deadzone
