Playseat Revolution to 2DOF

I ordered Arduino Uno as i want to be sure that it is not Ard Mega related problem... There are some differences between those boards on USB-Serial side (if it matters).

Not sure would that be the case, but weather doing exactly as documentations says, nothing happens on motor side

If i had more knowledge, it might be possible to check if SMC3 would work with Mega. I haven't seen on this forum that anyone uses other than Ard Uno?

I see the light in the end of tunnel...

Got a Uno and got my motors turning, so tuning starts from here.

Hi all.

Finally got MM's to work (someone should update the documentation...) It was not an easy task because zero out of 4 worked as they should.

But after hours and hours fiddling i got 2 of them working together (1 channel of each could provide enough juice to motors) -> I ordered some IBT-2's, hoping if they would work better. Heatsink is mandatory with these drivers, they get hot instantly after power on, but after applying these heatsink they don't get even warm (still temporary wiring in pic):



During tests with smc3 util, i got mechanical problems and then decided to change pots to the backside of motors with flexible tube-mount:



So, LFS is now working somehow (as i did not spend time tuning it) and today i tried Dirt Rally, but with no success (i got diy-license installed on both pc's).

Oh well, got to read some more forum and try find The Thing... It really is a long path to satisfaction

I'm actually surprised that my little motors do hang on. I got thrown good while trying RBR, because i forgot to reduce max % on game manager profile

One thing (not the only one), that i still haven't figured out, is that when assigning movement to axis, am i get only those simulated? So what to choose for 2dof to get best out of it? How to get good feeling to road surface and g-forces?

Ok, i'm asking this diffenretly. Should i feel car revving, road texture, bumps on the road, etc. when choosing only sway and surge. On 2dof, i don't see any other would be preferable?

And a short video driving RBR

Ideally for maximum immersion you want to be tuning (Surge,Sway,Heave,Pitch&roll) into your Axis Assignment settings for your 2dof,,, Heave for road texture & ground bumps as noorbeast has pointed out ,,,and Pitch and Roll is for road elevation and wot not,,.

But still, i can use only 2 forces at the time? Why bother to tune others than what are assigned to axis? I haven't seen any evidence that software would try to sum up other forces to ones that are assigned...

The other thing with the plugins... Wouldn't it be wise to category them according to which version of Simtools they work with? I do play some old games and i found that many plugins are not updated to ver 2. It also affects the fact how many usable plugins there are, not 94....

Still, awesome work from all of u guys! Beats commercial software solutions 100-1.

It works pretty similar to a FFB wheel really ,,,,imagine taking all the road bumps ,textures & rumbles out of your wheel ,, you would just be left with the smooth force of turning which is quite a boring experience if your used to feeling all the cool effects the wheel gives you normally ,,,,,

So it's the same when you add Heave roll & Pitch into the mix you get to feel ,,,Road texture and bumps from Heave,,,, Road tilt when your going up banks or barrel rolls from Roll ,,,and with Pitch you get the feeling of going up or down hills plus the cool feeling of weightlessness when you go over jumps and take off on rally tracks ,,,,,but anyways you get the point,,,,,

Tune them all separate and write them down ,,then add and blend them all together and jobs a good un

That's just Great news! Thanks for clarifying those things thoroughly.

Hi all! After tuning forces, seat makes a whole lot more than i expected...

I assigned all but YAW, because in common sense it seems to be undoable with 2dof? What do you think?

I got some new/upgrade parts: ibt-2's and a bit more powerfull wipermotors (still the cheapest!). I'll switch them if i get bored or there will be some failure.... As said before, motor wattage is not issue, but mechanical durability is limited with these wipermotors.
Thank god, i got Dirt 4 working straight a way, thanks to plugin provided by @value1 . Hopefully one day Dirt Rally will shake me also

Hi!

Assetto Corsa...Audi S1...Highlands --> broken motor axel....

Oh well, i guess my upgrade-time came earlier than i though....

Finally got my motors changed. From 30W to ... 40W? Maybe, but they actually are not rated. Criteria for choosing these was that they had fixed lever, so it was easier to weld cranks. I connected them with new ball-joints. These must be more silent than my first ones, which had small play on each.

After few test round, it was clear that one of my MM's couldn't drive all needed power to other direction, it acted very lazy. So, i took another job and wired IBT-2's. I'm so glad i had ordered them...

After many hours, got most electric parts boxed...and CV-joint greased.

It all seems good at the moment (i remembered to change smc3's mode from 1 to 2), just needs more tuning with software!

Oh, i totally forgot that i made handbrake, because can't rally without it...

New mounting plate for wheel and shifter, hole for handbrake:


under table...


microswitch with flexible mount...

A little video of Dirt4 - Rallycross...

...and bad lap of my axle breaker...

I've been busy driving, so not a lot of updates lately.... But i finally got harnesses installed. It sure helps to get much more motion-feeling, though my setup is quite lively even without. I had to add clip limit, because inertia took motors over to cut-point... just a small adjustment.



It is so hard to decide weather to keep whole frame in motion or just transfer it into seat mover...

This thing is too big with monitors to go 'inside' the house. Basic problem of construction is that monitors has to be too high (me being tall and seat being high enough that pedals can tilt forward), so no ordinary table suits under.

I think that because i basicly only want to do Rallying, it needs to have 'g-force motions' and i'm afraid that seat mover don't have it enough. It is true that these harsh movements makes driving only more difficult, without helping to feel the grip to road, but i think that is the point.

We'll see...

My 25€-motors have worked well and i think i'll order two more, just to make sure that there will be only minimal down-time . I already got new pair of IBT-2's in case too. I would not recommend Moto Monsters to anyone. These ibt's was around 25€ a piece.

So, at the moment i'm very pleased to the built! Vroom vroom
