Low cost 2DOF/3DOF/6DOF motion simulator - DOF REALITY

Well I get to throw my hat into the ring. Just purchased the P3. I asked Igor if this is a finished product now. I made it through 2018 of this thread and it seemed most people were happy with a few unfortunate exceptions. I decided to move forward when I saw that by and large people said their support was amazing. I confirmed this when a Monday morning email was responded to in minutes and follow emails the same.

I am planning on using this in Vr exclusively for racing sims. I'll report back my findings in order to pay forward all of thr hard work you all have put into this thread being so informative.

I do still have a question for anyone, what seat did you purchase, do you like it and why?

I simply slide my seat until I am wobbling in the free play area of the gearbox. If you rock your body front to back, you should feel the free play in the gear box. If you don't, then you are putting a high load on the motors.

Is there someone who knows the differences between H/P3 motors?

The P motors are more powerful and anecdotally means you don't have to be overly fussy about balancing the rig to get a smooth, shake free ride. The H motors tend to have issues with the rig shaking when unbalanced and can overheat if stressed too far. The H motors perform well on a balanced rig.

Thanks GWiz! Do you know the differences of technical specs motors? Is possible to identify?

There's some info on the main page of the DOFReality website. I think they have changed the motors over time though, I seem to recall seeing people discussing different gearbox ratios in a Facebook thread, I notice the new motors have DOFReality written on them which the old ones didn't. (Could just be the addition of some stickers of course!).

This looks really good. whats the total shipping weight and dimensions

Hi, I'm working with DOF Reality's H3, and I'm leaving a question because there's a problem.
I download the files (interface settings) of the links you provided in the first post and add them to the program, and my simulator's movement is strange.
This phenomenon occurs even though the setting value has not been changed much.

1 . When I run a test or turn on a linked game, the simulator is already in the middle, but it's moving to one side.
2. When a test or game is terminated, it is a phenomenon in which it slowly returns to the center after moving all the way to the maximum on the left.
3 . In addition, the simulator moves as if it were snapped, even if the value being sent (in a test or game) went up very slowly.
( This is a statement about the results of the previous comparison using SRS.
+ If there is a problem with mentioning another program, I will correct it right away. )

▲ I add my settings status.
+ If I want to use the Yaw value from the interface you provided, how should I add it?

sounds like a one of your motor driver is broken

you might need this BTS7960B

try testing each axis using that smc utility

My PC still has SRS (Sim Racing Studio) installed, so I tested it with it and it works fine.
(+ Smooth movement)
So I think there is a problem with the interface or setting.

Do you have any more predictions about the cause of other problems, not motor drivers?

+ I'm not only using the simulator, but also DOF reality's Motion box, is it possible that it's not compatible with the sim tools method?

If you're running SimTools 2.5 try 2.4. I had the same problem you're describing when I updated to 2.5.

Tried installing over 2.4; clean install; wiping out the APPDATA folder, clean install and reinstalling the plugin...nothing worked for me with 2.5.

Thank you so much for your help!!

For now, I only did the Output Test, but when I used 2.4 Version as you said, I couldn't see the phenomenon I was talking about.
I'll have to further confirm that the movement is still unnatural, but I'm so happy.

Once again, thank you for your help.

Thank you for your reply.
I don't know because I set it up by referring to the presets and videos provided in this post. I'll have to check a little more.

And I attach the video I took just in case.


I thought there was a lack of explanation for the disconnected movement I was talking about.
(Problem 1 and 2 above has been resolved.
Once again, thank you to Mechromancer!)

I'm applying it while looking at what noorbeast (Thanks, noorbeast!) wrote, but there seems to be a problem.

With reference to the SimTool axis movements above, the direction I want to use is Driving up/down Hill, Tilt to the left/right, and left/right rotation (Extra1 in the video).

In all directions, especially when Pitch is controlled, there is a problem of alternating movements like stairs.
In addition, there is a problem of sudden movement when the slider is controlled to a near maximum (90%?) level.

It doesn't appear when controlled by other tools, so I think I set it up wrong, so can you tell me how to fix it?

The setting value remains the setting of the existing one: DofReality H3 Preset (modified some range of axis usage).
(Actually, I keep testing like smoothing, but all same problem. So I wrote remain at Preset. )



I attach the video I took just in case.

Hi, noorbeast.
I applied and tested the methods you told me.

First, modifying the computer's geographical settings worked, but it does not seem to have been fundamentally resolved.

When the roll moves in the left direction (by the way I see it), it appears to move smoothly (previously, I remember that the left side moves unnaturally), and when it moves in the right direction, it appears to move suddenly.
And it's not clear, but it looks like the maximums on the left and right are different.

When dealing with Pitch, there seems to be a problem that both sides do not rise at the same time, with the left axis rising by a certain amount, and the right axis rising after all the right axis rises. (in addition to the previous story of moving like a stairwell)

Secondly, I modified it by applying the existing preset. (Except Extra1, every Axis Assignment allocation were divided in half)

Third, I'm not good at English, so I'm asking you, is it right that you have to move in different directions when you move the sliders of Roll and Sway during the OutPut Test?

Before, you told me the same story, but I didn't know what I understood and how to proceed with the setup, so I couldn't do it properly. Is there any way to set it up in Game Engine?
Are you saying that it should be connected differently when connected to the Motion Box? (If not Dof reality, arduino or Motor)
