    They are neat little devices and it really depends what you use them for. It is only an Input/Output device, not a controller.

    To control a platform like yours with X-Sim you will need a software PID.

    yes, but with synaptrix , there are a PID fonctionnality.
    at this day, i use a velleman card to move my simulator, and it is a good begining for make simply a simulator.

    it is not possible for all people to make a card interface, velleman product is a good solution, quality and fonctionnality are correct and there are no job, its a good help.
    i think a solution was found with synaptrix PID in the new Xsim version...

    There is no PID control in the synaptrix. Can you explain what you are referring to?

    Yes you can build a simulator with synaptrix, but you only have one motor speed on your simulator right?

    Synaptrix PID in the next X-Sim version? If this is true then I will be eager to see it!

    in synaptrix, when you use Dynamic speed, there are a PID.
    Sirnoname say , ther is a bug whith this actual version, he say whith the futur new version the problem will be corrected.
    i have no one speed, i have dynamic speed with dynamic speed i, the synaptrix.

    i have sometimes bug, because my motors( when there are a lot of speed) go over the pot limit, and my motor turnaround.
    but it is not a big problem, the result is very , very correct and i see this problem with roller coaster only.
    if i reduce the % axis, there are no problem .

    I see! Thank you!

    Your problem is too high PID gains. The motor have too much overshoot because either the I or P term is too high. Try to lover them one by one, and increase D a little.

    no problem! ;D
    i don't know if it possible i try to set but i don't found a correct setting.... :thbd: :(

    Sirnoname say, there are a bug in this section may it'is my problem, but i m'not sure because i use Dynamic speed with a special setting .
    to have a correct solution mouvement i put all setting in -100% in dynamic speed may be it is the problem.

    but it's not important because like you say, i make an electronic interface to covert analog to -100%....0....+100% .
    with this interface it's work like tnanos card.
