My 2DOF simulator project

Hello,

I have been on this forum for a while. Just a month ago, I decided to start thinking about building the 2DoF simulator. The idea is to minimize the cost.

There are a few examples I tried to follow for the motor system.

@iLLuac4 in the post https://www.xsimulator.net/community/threads/simlab-gt2-to-2dof-conversion.13948/

For the structure, I tried to use a similar design of @noorbeast in the post https://www.xsimulator.net/community/threads/dx-compact-simulator.5866/

Forget to mention that I am currently based in the UK.

What I currently have are the following:
Two motors from Amazon UK. The same model 24V 250W 75rpm.
Meanwell LRS-350-24
Motor controller BTS7960B DC 43A
Electronics box with 3D printed front panel.
U joint from Bearmach (BR1741 and BR0664).
A lot of different Arduino and RaspberryPi.
very basic 10k potentiometers

Sorry, there are no links yet. I cannot share external links yet.

For the design, I tried to combine @Caveman 's Prototype Racing Sim v4 and @noorbeast DX design. Currently will be 2DOF, but for the future, I want to add traction loss as well. The design is based on the aluminum profiles. It is not finished but will be like this.

For anyone based in UK.
Here is the source for the motor.
Unfortunately, the price increase from ~£50 to £87.

It cost me a lot of time to find a cheap u-joint.

and https://bearmach.com/product/propsh...656-uj-joint-br-1741-suitable-br-0664/BR 0664

Two yoke £10.58*2
one joint £4.88
shipping is £7.5
there is a 10% discount code for signing up for the news.

Hope that helps anyone who needs the U-joint.

That link for the u joint is a life saver, have you tested it yet?

I have not tested it yet. In the current stage, I am still designing the rig. I plan to build it using an aluminium profile or strut because I don't have a welder. I need to get the key component like this U-joint, rose rod and motor arm, then I can fix my design and order the strut.
I have some basic measurements for you, hope it helps.
I think the angle will go +- 15 degrees.

Cheers mate, I got one delivered yesterday and had my mechanic put it all together for me cause I didn’t have a clamp . Cheers for the info.
I’ll get my rig posted with where I’m at on it at some point this week.

Life was not easy, especially with two boys. Here are some updates about this project.
First, the electronics box was filled with two Meanwell power supplies 24V, 350W with two BTS7960B DC 43A stepper motor Driver.
Followed this link
https://www.xsimulator.net/communit...3dof-motor-driver-and-windows-utilities.4957/
to test the SMC3 for the initial setup. Worked!

Next is to finalize the design of the simulator.

Get the frame ordered from https://www.aluminium-profile.co.uk/. Two types of holes are needed. One is the M12 to connect the M12 end rod for the motor arm. One is the M8 hole to connect the U joint.
Begin the building.
1. Bottom frame.


2. Top Frame.


3. Motors.


4. Seat and mounting frame.


5. Attach Logitec G29
