    No need to change the dip switches now. But if you like to keep LCD menu ON, you just place a jumper on S4

    no need in games, I prefer to have a maximum of data for the resolution and quality of effects!
    the more resolution there is, the better for me!

    I already updated my old AMC 128 with this firmware, I tested tonight, for the moment everything is fine. ;)

    Very good idea!
    Its always the first thing I tell people to check when they are up and running.
    very handy for setup, but not needed during normal usage.
    take care,

    For the moment the resolution is not enough.
    I do not have enough small effects, I try any combination, it does not give me satisfaction.
    I can not wait to test the new AMC with 12 bits in and out.

    I hope to get a better result.
    I have a fear,
    because I wore before better results it seems to me.

    is there a solution to increase, improve the resolution, the details in the effects?

    My Motion Simulator:
    AC motor, Motion platform, 4DOF, 6DOF
    Remember the VFD inverters usually have minimum 0.1 sec ramp for acceleration / deceleration. I'm not sure if you can set this lower than that.

    For comparison, the AMC1280USB has response time of 0.002 sec (2ms) from the computer data that is 100 times more resolution than the AC motor can handle.

    With 12-bit resolution you will get more precise positioning, but doesn't mean you will achieve much "vibration" motion through the AC motors, perhaps low frequency vibration (up to 10Hz).

    If you wish much more resolution, you will need smaller motors with less inertia, perhaps DC motors, or AC Servomotors that are designed for fast and precise motion.

    Thanks

    on the drives, the 2 main time settings are already at the lowest:
    I am already set to the lowest at 0.1sec for the ramp
    and the analog response time is at 0 too.

    yes I will see the difference with 12 bits
    I hope an improvement anyway
    there is a response time also on the other engines.
    the servomotors will be better, but the price is important ...
    Maybe one day ....

    Simvibe with the ButtKicker LFE will do the work otherwise!

    I am really divided on the resolution.
    before I got a result that seemed much better ....
    it bothers me, because I think there is a difference today that I do not explain.
    I had fun comparing to a servomotor :)

    is it possible to see if the motors are too fast for a given setting or not fast enough?

    I had to lower the speed of my engines to get a better result.

    I have a good example of my adjustment problem between motor stroke and engine speed.
    if I had a 5 meter rail and my simulator slides on it.
    it's for the Surge effect.
    I put the axis at 100%
    the effect values at 3 (auto recording at 2.5)

    it would not be exploitable, it would be too violent, small effects would be very large and therefore not realistic.

    I think I'm dealing with this kind of problem.
    it's complicated to set the Surge effect on "long distance" axes

    what would be the type of setting for this configuration?

    Another example, a Cruden simulator with 50cm of displacement or more?
    for the momment,
    the solution I found: it is to lower the speed of the engine to 16 trs and put 20% of the axis.
    it's a shame not to be able to exploit more than%

    what is the output resolution of Simtools? 8 bits / 10 bits / 12/16/32 bits?
    is it possible to increase and change the resolution?

    7 to 32bit.
    You set the output resolution in the Interface settings of Game Engine.

    for the card yes, but the plugin, the infos of the game?
    it work in how many bits?

    the sensations, the quality of the effects, the resolution seems much better with version 2.2! :)

    now it's less violent and there are more details. :thumbs

    the new version brings more resolution?
    what causes this improvement?

    so there was a problem before with version 2

    it is therefore corrected.

    on what setting in Simtools I have to play if I have a very very fast engine?

    30 rpm output reducer, the sensations are good but too violent how to keep this speed for small effects, vibration ... and decrease violence on large displacements?

    I of course did that.
    to reduce speed and violence I have to increase the effects value.
    or reduce the% of axis.
    I was wondering if there was not another alternative

    I feel that the quality of the effects is not constant.
    one day I think the simulator works great, the next day, I have the impression that it is another simulator, the effects are not great ...

    what could make a difference?

    the resolution, the FPS? which parrameters could cause this?
    my PC ?

    it's more violent, and less good about quality, resolution.
    it seems violent.
    in fact I describe this defect for some time without understanding where the problem comes from ...
    Thank you
