    Hi all,

    I'm Paul from the Netherlands.

    After selling my playseat with t500 rs 2 years ago i got back into simracing with a new rig see further for the details.

    I'm building an active seatbelt tensioner and motion for the first time its a project to start and when its working fine and i know how to program it i will start building a 3dof.

    The mechanics are finished i start with one steppermotor nema 23 i can alwas upgrade to two of bigger motors.

    I have for electronics:

    Arduino uno
    Tb 6600 microstep driver
    nema 23 stepper motor 3,5A
    LRS 50 powersupply 12v max 4,5A

    I run the simtools software

    Now i only need a code for the arduino to start with and i have no idea where to start is there anyone that can help i'm good in mechanical work but programming is another thing.

    For my rig i run:
    -80-20 simlab gt
    -lcd seat
    -sabelt 6point harnes

    -Fanatec csw 2.5
    -Fanatec csl elite pedals with loadcell
    -Fanatec p1 rim

    -home made seq shifter (feels really good and mechanical i wil make a thread from the build)
    -home made handbrake (button operated for now but wil update to loadcell in the future after i learned to program)
    -home made 7 and reverse Hshifter (feels really good and mechanical i wil make a thread from the build) its based on the Frex h shifter design)
    -home made dash from old sony phone running dashpanel and build a nice case around it

    -Msi 27inch 165hz screen
    -home build pc specs:
    *Gigabyte X570 gamingX
    *AMD Ryzen 5 3600x
    *Corsair 850w
    *Gigabyte RX5700XT Aorus 8G
    *Samsung SSD M2
    *2x 16GB 3200 RGB pro veng.
    *Cablemod sleaved cables
    *NZXT Kraken x63 watercooler


    I hope someone can help me getting started with the programming.

    @Lebois recently built actuators using steppers, so may be able to offer some advice.

    Hi. Nice rig. I will be watching your thread. For now I try to do belt tensioner with DC brushed motor. But I have some problems. I also wonder how it's working with stepper motor. Good luck

    I had al lot of these Parts i had already so thats why is try steppermotor.

    made a test board this evening so i can start testing

    @Krzysztof Dej what problems do you encounter? 6E8FDC22-C51C-44C6-8728-1860A949C4D1.jpeg 53ABA6D3-C946-4247-8E96-298AA186B2B7.jpeg

    Wow. Can u show whot is this controller and how u wire it from motor to arduino? Why these switches is for? My problem was that motor caused a short circuit when I mount it on rig somehow. Now I'm waiting for 3d printing part to separate it from rig. But I see now I have another problem with Smc3Utils config. My 2dof motors config doesn't work with this small motor. So I see i will have a lots of play with it

    The controller is a bt6600

    the Wiring is not ready yet i’m going to figure it out today and try To write a code I Made the switches because i can do Some testing (basics) i never wrote a code before the black switch on the left is for cutting powersupply with one toutch just in case.

    Wen i figured out wiring i write it here

    It's easy for me to upgrade but for now i first need to get it running i never programmed/write code before so when i know how to do that i can modify it in 2/3 hours to a double motor setup

    @hoyang i watched your project looks really nice can you help me with code and wiring to get started.

    Little update,

    I orderd ibt 2 motorcontroller and wipermotor.

    why? Because there is way more to Found About coding and wiring so i think Its an easyer route To start with motionsimulation.

    made a Nice electronics box today C6C723D7-13F9-49C2-9E22-61F44114DAE5.jpeg FD46A4B1-49AB-49DB-BAD0-004AE3144685.jpeg 4EC9648C-EB8C-4D2A-8F80-2D2C6F564D64.jpeg

    608DA03D-678E-45E6-B1D4-B4A9347557B6.jpeg Made it possible to mount it underneat the chair D2F2B67D-E797-4478-A88D-86B9B9285EB1.jpeg

    the Wiper motor is on Its way do i hope I can do Some testing this evening.

    can i use the arduino code for 2/3 dof and only use it on one motor?

    Yes you can use code such as SMC3 with just one motor.

    Found it

    this is a vw polo 6n front Wiper motor

    remove the plate inside 1D229578-F87F-4E6F-8A74-77482AB28DC7.jpeg 6576E323-1229-42BF-A831-0CAB59847B77.jpeg then remove the cap and cut 1 wire the one with Some ground on the board dont do it like me i cut them al three so i had To solder 2 back 9CC74B71-A684-49FB-AA9D-C1C5A76F129B.jpeg i already cut it here CFF595A0-7AF1-486D-B7D0-03AD44E40F5F.jpeg
