Simucube DIY thread

20Nm I think for the small mige and 30nm for the big mige.

Wow this is a lot of more than Fanatec! Is it very difficult to built this wheel?
What cost it ?

Just look in this forum plenty to look at

Plus 6Nm for Small Mige and 9nm i think with Big Mige and a MONSTER Psu + Overclocking. Tho if you feel the need to overclock a Big Mige or even go with a Higher powdered motor....your imo clinically Insane.

Nick (or anybody else for that matter), do you happen to know what the difference is between the new Cube setup vs the old Argon setup from a performance standpoint. I'm rocking the old argon setup and while it looks to be a load more difficult to wire it seems to perform just fine. I have on more then one occasion had the wheel snap back in dirt rally and practically break a wrist.

Firmware and overall tune ability when we get the new software that's being built up, The Cube's having the Firmware worked on right now. And overall future support will be much better with a Cube than with a Argon/Discovery setup.


Performance isn't really the question here. Both Argon and Cube can send 100% juice to the wheel in any circumstance if your settings allow.


THUMBS up Driving technique is HIGHLY highly recommended when your new.

What is going on with a firmware rewrite? Not performance you say? Are they just trying to get away from mmos? Is there a discussion going on right now about it?

Hello Guys,
I am busy testing new open source fw with Mika.

Good progress, here is something I posted on last night.

Cheers,
Beano (Granite Devices)

@RacingMat from RacingFR Forums: I cannot seem to post any more on the website, even I am logged in. Do you know if there are problems with foreigners trying to access? Appreciate your feedback - if you can post the below quote in my Bruteforce 3 thread there, I would appreciate it!

And it seems I need 3 posts before I can post a link, what a mess

And now I am spamming, shame on you, Forum.

And finally, here is the bloody update. Gawd, let's hope this one goes through.

Sweeeet, I see the Axis and stuff is coming along nicely.

Thanks for sharing.

Cheers Nick, no dramas.

Yes, all the analog inputs are working fine now, Mika is currently busy coding the auto-configuration stuff for the servo setup. So very good progress.

The filters will follow towards the middle to the end of next week, thereafter smooth sailing to do debouncing code for the binary inputs.

Almost there, I will keep you guys posted.

Beano

I will leave these screenshots here for now.

History in the making. Look at the encoder selection and the associated resolution in the GUI.







I couldn't drive with the AKM53G/ BiSS today though, as the servo uses NEMA mounting it seems. I have a bracket that I will probably modify tomorrow. Will give it a good go then.

I have, however, been murdering the Moocedes around SPA today, got a good few hours in on the alpha Mika sent yesterday. Was running with the other servo I got off Davy Watts last time, the AKM53K with the 40k encoder. No issues whatsoever, tracking stayed true and accurate, even though I tried to induce weird behaviour. Even at max current and torque, it performed flawlessly.

New IONI fw has a few neat new and enhanced features, and it compliments the OS FW of the Simucube very, very well.

Considering it is alpha, I have to be honest and say, even this early, I find it outperforms MMoS in terms of latency, as well as improved feel and response. Of course, the AKM53k is a superb servo also, and I luv that I can hit it hard with friction, inertia and damping, changing the complete ffb behaviour, but still retaining huge amounts of fidelity.

This all without Tero's new special ffb filter - woooo.....good times coming.

More feedback later, I will do a few more hours testing tonight, but I suspect the base fw is very solid at this point. GUI also working seamlessly with the Simucube fw now, seems Mika has squashed all the bugs I had earlier.

Laters, have a great one!

PS: I think next weekend, I will wire up the MiGe with an extra SinCos encoder I have. Will be a pretty radical combo that too, what was it, 1M CPR if memory serves

Beano

Beano, In general, the High CPR number...is it really THAT critical ? What are the main differences you feel and is it really worth the extra $$ to replace or upgrade ?

Hi Nick,
With the new open-source fw, 10k por encoder will be very capable indeed, and should satisfy even the most demanding user.

See my feedback below after testing the latest alpha Mika shared with me tonight.

It's happening

1st Closed Beta 0.4.1




It is quite common on this forum to find those that doesn't believe in the contribution a good wheel can make.

Let me show you the consistency you can have with a low-latency input device, with quality FFB - in the below screenshot, I am doing groups of 4 laps each (1 outlap/3 hotlaps) testing in the Moocedes around SPA.

I am running around 20NM torque here, weather was at 24deg C track temp.

Consistency through the roof. The slight variance between the different groups, eas me playing with the rear toe to stabilize the back due to a very loose oversteer on/off throttle set I developed.

I will just leave this here. Please note I am no alien, just an old fart with poor eyesight

Looking good !!

Hello Guys,
As promised earlier, a video, with me doing some talking and some driving - should give you an idea how the wheel is behaving with the new firmware.

It's about 15 minutes long. Hopefully it answers some questions.
