    Kudos to you both for the initiative and by making such valuable work easily accessible to others.

    When the new thread is done can it please make mention of 3D hubs located around the world, for those who would like to have the 3D printed parts made but who don't own a 3D printer: http://www.xsimulator.net/community/faq/3d-printing-no-printer-no-problem-use-the-hub.129/

    @Archie that is an interesting design for 3d printers, i like their use of 80/20 just seems like a lot for such a little guy! I would definitely recommend researching the Prusa i3 open source design. they have a pretty big following at the moment have and driven "affordable" 3d printing since the start of the patent for 3d printing has expired. Even if you dont go with a build like the one i posted there are a lot of resources out there on building one yourself. the great part out them is there are a ton up upgrades that you just print from your printer that cost you next to nothing once you have the bare bones. I like the Prusa a lot for that reason, and the Marlin firmware it runs is always enhancing and you get the updates at no cost since its all on a public github repo - either fun road of 3d printing you go down if you have any questions just message me and ill be happy to help out any way i can

    Okay so im in need of some help my one JRK is running really really hot and i cant figure out why. The heat problem is always on the right motor if looking at the rig from the back. I have switched JRKs, Motor, Power wires, data wires and the problem still stays with the right side even though all the hardware is has been changed. The only thing i didnt change was the POT but in JRK utility the pot is reading consistent values and isnt jumping all over the place so it didnt seem like that could be it. Im using the same PID values on all jrks just different motor limits for obvious reasons. Anyone have this issue before or can shed some light on this issue?

    have you got a fan on it? Have you got a heatsink on the big chip? Does the JRK stop working after a while of use? Whats the motor limits on the hot JRK and whats the motor limits on the other?

    all jrks i have tested are the ones in the box i built with scalhoun. they have fans on them the entire time and have heat sinks on them, i can put one motor and pot on the jrk and it doesnt get hot i move it to right side and it does, regardless of the motor jrk cables etc that i use as i have changed all of them. the limits im using are only different in the sense one is reversed to the other since they are same direction phyically but move oposite of each other ill post the screen shots of it tonight or tomorrow - it without a doubt isnt the physical properties of the jrk motor or wiring as all of them being used on the left side of rig doesnt cause heat problems. the only two factors that were constant for right side is jrk config file as i loaded this on every jrk i tested for that side (however like i said the PID is the exact same for all jrks and the motor direction values are recalibrated when i change the jrk for that side ie i set the max and min via wizard each time. all other settings are identical to the left side)

    mmm...ok then, post up pics of utility settings then.
    Again, does the JRK shut down or does it keep running despite getting hot.
    Its the right hand motor, shoulder mount is it?

    In addition to posting the settings can you advise if there are any JRK errors reported, such as a motor drive error.

    so another small not so informative update. Havent posted pictures of the rig since i painted everything and cleaned it up more and added seatbelt. I moved it to my basement so the wiring has gone to shit again, but don't plan on redoing all of it until i get my 80/20 design ordered and built. Also are two simple shots of the OSW (which by the way is everything you can hope it to be).

    Any questions please ask id be happy to help. Will post more pictures of the OSW box once i get all the mounts designed & printed and have it looking pretty (right now its just a wirey mess)

    Hi @rundmg, I have an obutto that I want to convert. In your earlier posts, you were using the obutto seat but now i see that you have switched to a different one. Any major reason?

    Hey @BondeX there was 3 major reasons I changed the seat out and then a few side benefits to doing it in the process. The main reason is that after spending a little over $1k on the Revolution and only using a few bits of it i knew that id rather build an entire platform and sell the Rev to recoup some costs which would mean replacing the parts i was still currently using, 2nd when adding 3dof (still havent gotten around to doing yet) the Obutto stuff doesnt really work anymore without it looking very hacked, third i knew i wanted to add bigger screens that the triple monitor mounts couldn't support...after replacing the screens 1 month later they released the preorder for Rift CV so that could turn out to be a waste of money on them but we shall see.

    The side benefits of replacing the seat are one its much much lighter, two its much more ridged since its a solid construction seat with less points of flex/play, and three it just looks badass, however there are some cons, the cheap and easy way to monting the seat to the base and the back rail became much more difficult which i will post some of the pics of the frame i made to support the new seat properly

    Starting out modding a Obutto rig is definitely the cheaper way to go and reduces the amount of build for going motion, but as you go down the rabbit hole that is sim rigs you'll probably quickly realize you want to make your own rig entirely to make it exactly how you want but i have to say the initial build i did felt fantastic

    Attached is the current status of my rig and how i went about replacing the Obutto in a budget conscious way, no surprise i took some notes of my brothers rig and refined where i could.

    if you have any questions or need help if you decide to convert it just let me know id be happy to help

    @rundmg, first of all I would like to say that what an amazing job you have done here. While going through your thread I got so excited that I asked the question first instead of commending your work :)

    So yeah the reasons you have given definitely make sense. I have an obutto ozone and I was thinking about few options: 1) Move the whole obutto rig (3dof) without the monitors. 2) Just use the obutto seat and the base the seat is on as a seat mover.

    Now i know revolution is much more expensive so using bit sand pieces of it does not make sense but since I own an Ozone which cost me only $434, I believe if I can make use of any of its parts, it will be worth it.

    Any thoughts would be appreciated. Thanks

    my brother did a Ozone conversion which is linked here which can give you an idea of what he did with his (pretty much the same thing). putting it on a platform for 3dof is def a reasonable option, we thought about doing that but for long term customization we decided to just built our own. I've designed a frame we'd like to do out of 80/20 but just haven't had to time to get around to getting a finalized parts lists and pony'n up the money for it since the hardware for it can get salty.

    either way starting off with converting it is the way to go, less variables to wrap your head around during build and you can focus on the motion parts and software much easier which can be a slight learning curve of trial and error, thankfull these forums are fantastic for any issues you may run into

    Hi @rundmg, so when you and your brother were still using obutto seat, did it hold up pretty well?

    yea i never had any issues with the at all, they are built very well, i am only 135lbs tho, it help up fine with heavier people on it but they were never on it for extended periods of time so you may run into issues there if someone extremely heavy is on it
