    I pardon because of too much questions I did ask. As I am newbie here. If you can please let me know
    1. Can a pair of 12v 120w motors do the job for 2dof? what would be the max load it can handle? best for 80kg load? can I use stepper motor instead?

    2. Can I use pc 400w smps for power supply to the motors.
    3. By using ibt_2 could burn itself? max continues duration to run at a time?

    Motor and gearbox selection depends on the actual design, a compact rig needs lots of torque while a traditional shoulder mount benefits from a higher ratio worm drive.

    Fortunately there are now some great tools available to help check your design, so use Motion Visualizer and/or SimCalc to help get your head around the design Vs physics trade offs:

    Motion Visualizer: https://www.xsimulator.net/community/faq/motion-visualizer.389/

    SimCalc: https://www.xsimulator.net/communit...e-linear-speed-and-forces-of-your-design.270/

    PSU selection in turn depends a bit on the motors chosen for a given design, LED PSUs are pretty cheap and are available in a vast array of specs, or you can modify server PSUs: https://www.xsimulator.net/communit...ver-power-supplies-as-cheap-powerful-psus.54/

    Motion rigs generate significant powere spikes in fast reversals, so go higher in PSU specs than just being able to run a given motor.

    It is possible to damage hardware through overrloading or poor wiring, but again there are hardware choices depending on other hardware chosen, usually the more robust hardware is the more expensive it is.
