    hi everyone and happy holidays

    9 months later i am still working on a 6dof
    my coworker is helping me weld a frame. im just concerned about how much weight the actuators will hold.
    using conventional 6dof design with e30-400 motors, 60x20 vslot rail and 2.5mm thick carbon fiber rods (30mmOD, 25mmID), im starting to feel skeptical of supported weight.

    frame seems like it will be 40-50 lbs. steel tube gaming seat with sliders will be about 50lbs.. thats not even with joysticks and accesories..

    i picked a noblechair gaming seat with adjustable back... so you guys think the chair is too much weight?

    I have no clue.
    But, linear actuator are quite powerful.
    If they are not, you will see it in their speed and how hot your motors will be (and the smoke coming out of them).
    The rest of your journey depends on one thing:

    Money.

    I am serious.
    If you want to make sure that you do not make any mistake, chose the right design and have optimal results, their is a lot of things to verify. Check how much one actuator can lift, how fast, at what inclination, and divide by the 6 of them. Do the math, weight all and everything, plus the rest, and don't forget yourself and your last meal. Make sure your motor are up to the task. Brace yourself, because you are in it for the next two years at least. But you'll save money.
    If you're willing to risk some money (more toward a lot then a little), just keep on doing things, without worrying too much. You'll make mistakes, you'll repair them. It is as simple as that. It is at least 4 times faster than thinking everything to perfection. As long as you are not putting yourself (or anyone else) at risk of injuries or a little premature death, you'll should be fine. It more frustrating at time, but it's more fun too, strangely.

    thanks for advice @Pierre Lalancette
    are you still using E30-150's in your build?

    Indeed. Always at half their maximum power. I may change that in the future after more calibration.
