    I have planned to build my 6DOF SIM at the begining of this year, and I built a small model to study SIM TOOLS with a lot of warm-hearted people's help, thanks to all of you. @Pit @SilentChill @noorbeast @bruce stephen @SeatTime @BlazinH etc.

    attached my SIM design.

    Last weekend I have soldered my 6DOF SIM with stainless steel.

    BUT there is a problem, the height of pedal is too low which already meet with the motor's bracket.
    so I plan to increase the lever length from 560mm to 760mm. according to you guys's experience, is it OK?

    Thats got to be one of the nicest looking rigs for sure, wow. common issue with the front rake, maybe lengthen rods and trim some. if your going with a monitor i would save the weight and hang it from the ceiling. i mounted my monitor to my rig in the beginning/test phase but it felt a little UN-natural. again wow nice work. also you can flip and hang the logitech pedals with hardly any modding other than building a place for them to mount to.

    Simple et efficace, félicitation pour ce concept économique (à part l'inox ;) )

    Simple and efficient, congratulations for this economic concept (except stainless steel ;) )

    Great work. I don't want to be negative but I fear the axle on the levers are too long and as a result of this the rig will flex under fast movement.

    Hey Racing Mike, amazing build so far!

    I am brand new to the site and have been looking for a design ideas and I really like yours a lot. I literally have no clue as to where to begin. I have no software background but am pretty handy.

    to get a rough estimate on the cost of something like this, what would a ballpark estimate be? And how difficult is the software setup, like would I need to be a software engineer to get this working?

    Appreciate any feedback, and sorry if I offended you asking what the costs would be, i just want to know if this is feasible for my budget.

    Thanks!

    I'm still testing, later I will share more information.

    Till now I spent 3500 USD.

    Tonight the rig start moving. When I sit on to test, met 2 issue, one is the PSU frequently stop work due to some protection reason, another is 2 MMs damaged(2 MMs for each motor, should support 64 A), bad quality.
    Should I change to another driver board?

    The
    Simtool is very easy to standard, no need software background.

    Were are the heatsinks/fans for the MMs? Eg. - here is my setup for initial testing (using a CPU heatsink/cooler). There are also other ways to do this - Look in the FAQ or Project area. They will not take more than 6 amps without them.

    I have bought some heatsinks without fan, is it enough?

    Well it always depends on the actual load and on how big you heatsinks are ;-) But looking on all the projects here, most builds are using active cooling (with fans) - At least MMs with heatsinks and all other electronics put in a (self-made) box which has one or more fans genrating some airflow inside.

    One quick and easy solution can be found in the FAQ as mentioned:

    active cooling is recommended. they get hot quick. with your type of rig they won't last long without it.

    I would recommend the Sabertooth 2x32's they are an awesome bit of kit. They will never burn out and are really easy to setup and monitor everything that is going on in them. Just a bit pricey but deffo worth the money :)

    As for the heatsinks on the MM's like everyone else said you deffo need fans on them no matter what and really good solid connections for all wires to the board because if one comes off you will fry it, burn it and then of course smell it :D

    Edit: I think you will need some gas struts to help carry all that weight it looks heavy, if its not that heavy ignore me :)

    Yes, the gas strut is in the plan, after I confirm the length of lever I will add gas strut.

    Is there some extra feature useful sabertooth support ?

    @Racing Mike I am using 2x80lbs. x 20" dampers on the front and 1x60lbs. X 20"Damper at the back. They have an 18 inch stroke . The dampers make all the difference. I have a set of 100lbs but they were too much.

    Some of the MMs are burned out, I plan to purchase new MMs from eBay, my motor are 300w, does 6 MMs enough? Before I planned 12 to reduce each pcs load.

    No, need 12.
