    Having used both, IMO the performance/easy of use difference is great. AC servo motors FTW. For a non balanced Rig (Stewart Platform etc) a good DC setup is actually not that much cheaper, once you factor in good quality motors, drivers, feedback and power systems. Don't forget that the price of a AC servo motor normally covers also the matched power supply/driver, fitted encoder, cables and connectors.

    I am located in China. On Taobao, I can buy a cheap and stable DC motor driver board to drive my 24V 400W DC motor (the motor price is very low), as well as linear potentiometers with various stroke and low price. Moreover, the price of an 800W DC power supply is only 200rmb. So the cost of DC motor is lower! And this low-cost performance can fully meet my needs.

    Your time/money so the decision is always yours.

    I mean, if there's no big performance gap between the two solutions, why not use a lower cost one? But because I have no comparison, I don't know how to choose.

    Just choose. In a few months, you will want to redo it all again anyway. All sim makers are like that.

    I really appreciate your project sir. what about the power of the nema 23 stepper motor?? have you tested it?? i have read found no comparison between nema 23 and my1016. in my country these two dc motors are still easy to find at reasonable prices lol. and whether you can use a ballscrew with a screw length of 150mm travel 110mm ( length nut 40mm) I want to try to make 2 dof, or if possible for 4 dof sir. If that's possible, I'll immediately buy the ballscrew, because it's in a used goods warehouse. confused whether to use nema 23 or motor scooter my1016 or my6812. Thank you sir. Or someone can answer my question

    wow i like this a lot please do update us with the final product and parts and pricing as this looks like a future project for me once i become more knowledgeable in this science of motion rig lol.

    mh nice work for the diy linear actuators ... is there a need for the end switches if i use standard 12v motors plus a hall sensor ?

    I don't know what exactly a hall sensor is, but limit switches are never a bad idea. Not having them IS a bad idea.
