Want to build a 3dof with traction loss - but

    Hey guys

    I had a simxperience 2 dof, and later on i built my own virtual racing sim rig with a playseat + oculus + 8 pucks and simvibe. I actually prefered the simvibe approach and the non motion rig to the motion. But it dawned on me, that this was mainly because i had built my original simxperience wrong.

    Now i want to give it a go again - build my own customised 3dof with traction loss + simvibe. However, - browsing this forum gives me great ideas on other peoples builds, but... i am having a hard time finding out if there are plans, or just simple documents, where i can go and study the general idea on how you guys approach this?

    I mean, if i want to build the above, - where do i start? is it just browsing until i find someone that has made this kind of setup, and then hope they have laid out the plans, or is there another method which i cannot see atm?

    Any help/insight is much appreciated.

    You won't find much in the way of detailed plans around here, mostly just basic dimensions: https://www.xsimulator.net/community/faq/cockpit-design-dimensions.116/

    Have a look at existing member builds, that may help you refine your own project ideas: http://www.xsimulator.net/community/forums/diy-motion-simulator-projects.22/

    You will find plenty to get you started in the FAQs, from design software, dimension of sims, to PSUs, pots, motors, control hardware options, plus heaps more: http://www.xsimulator.net/community/faq/

    There is a glossary for all those acronyms we tend to use, which will help you decipher some descriptions: http://www.xsimulator.net/community/faq/glossary-of-acronyms-and-names.66/

    It's pretty much browsing other projects, looking on what's seems interesting to you and if there are no plans or sketches, you can always ask the questions in those threads.

    Try to use Searchbar, type 3DOF and check "search titles only" box, it will return you the list of all 3DOF projects, I am pretty sure most of them have "3dof" in their thread title.

    Thanks alot so far - very helpful. Ive been browsing your build, looks very very nice. One thing though; im still not entirely sure how much i can save by going the DIY way.

    Is there anyway you can try to put an estimated pricetag on the build youre doing now, so i have an idea of how much id actually save by going the DIY route? I realise that this is not the only reason why you would go DIY, but still, its a factor i have to consider!

    DIY needs a lot of time, collecting information, welding, drilling, wiring - if you have two left feets, go the commercial route. If you can spend lot of time in DIY, you will determine that the journey is the destination. Saving money is dependent of your skill level and your shopping list. Wasting money can be a result of buying wrong (low quality or too expensive) parts or a poor craftsmanship.

    Actually - im still in despair, let me fill this out a bit;

    I know how to do alot of things - i can weld, but dont have access to welding gear. I have a few 3d printers. Im good at soldering, but not particularly good at electrical stuff.

    Now, when i look at the various builds around here ( and ive looked alot ! ) it seems that there is always some information, but rarely ( havent found it yet ) any complete step by step information. I realise that this is probably because peoples builds will differ, and to most of you already in the process of doing your own build, or people that "can do this thing" will be able to glance at stuff and go "ah, ok, so i could do this and then".

    But for someone like me, that in theory should have no problem figuring this out as i usually dont have problems completing my projects, its daunting. I get how it all works - in theory. I get how to do it - in theory. But the actual practice is kinda hard to translate. Its hard to get started i feel.

    If i look at project X from someone, hes using this kind of motor, and project Y is using this instead. Project X might show a wiring diagram, but project Y does not show his wiring. In the end, i feel im taking in alot of information, but im still clueless as to how actually to go about it.

    So, can any of you reading this, maybe come up with a recommendation for a build i have missed in here which might be closer to an actual step-by-step guide? This would be immensely helpful, as i could then take all of that in, and if i chose to change a thing from that, im sure i could find another build thread with that one step being changed, thus being able to "insert it" into the original plan?

    I dont know if this makes sense, but it feels like thats whats holding me back.

    Im mainly looking to build a simple 2 dof, that can be expanded ad infinitum -- i know the expansion lies on me in terms of rethinking things, and i know ill run into areas where i have to take it apart and redo it (to add say loss of traction) - but im fine with that, as my line of thinking is once i get the 2dof working, ill know enough about it all, to be able to take it apart and rebuild it as a 3dof.

    I hope this makes sense? =)

    Hey Pit

    Thanks - i fully understand what you mean. I do alot of diy myself. I have built my own 3d printer, and my own cnc. But with those things, i always had a blueprint to follow - which i then strayed from - but understanding/having the blueprint was a huge help to begin with. I dont feel i can find anything that comes close to a blueprint with this; it feels like its "I BUILD THIS LET ME SHOW YOU 20% OF THE INFO". :) And that leaves me crippled, and unable to just get into it!

    A few years ago I was feeling as you do now. I never thought that my simulator will work one day. There is no "blueprint", but a bunch of users willing to help you with their experience and support.
