    I think most will be going VR so this will not be an issue,
    saying that a long shaft is not good ( although the servo bearing are very strong -leverage is not a good thing)

    I have new fitting + a thinner mech on the back of my formula wheel now so everything much closer to the servo
    ( sold the wheel in pic as the rear of it to big etc )

    Does anyone have any info about the Ioni pro HC? I've been told that you can use the full power of most of the motor options with this new "high current" version of the Ioni. I'm in the middle of planning a build and just wanted to know if anyone has any ideas or advice about this.

    I think I heard the same about the IONIzer. Would love info on both.

    Someone i've talked to said the IONI HC should be available in 3-4 weeks. Never heard of the IONIzer, but i'll probably just go for the HC since it's apparently a straight swap with the IONI Pro drive in an IONIcube, so the build would be similar to what most are using which i'd guess would give you a benefit in troubleshooting if you ever have a problem.

    I've posted about it a few times around here, I'll find it.

    Here you go...

    "The following is what Ollie told me (paraphrased):

    SIM-ple for IONI
    The SIM-ple for IONI replaces a lot of the parts you'd normally have to get like the IONICUBE, STM32F4Discovery, braking resistor, SMV2USB, etc. It also reduces the external cabling requirements. It (SIM-ple) is currently being validated, will start to be shipped in a couple weeks, and has a long waiting list as-well.

    IONIZER
    Granite Devices make an external power stage product called "IONIZER". Ollie will be modifying it so that it can be used with the IONI. This will allow currents of ~30A at 48V DC which should be good enough to drive the Big MiGe to 30 Nm. It will not be ready in the short-term."

    P.S. "IONI" refers to the IONI Pro, and that message was from around July or August of this year.

    That Sim-ple option sounds interesting, but also sounds like it would be a long wait if i tried getting that now. Does this Ollie person have a website or anything? The motor i'm getting is going to be about a month out, so i'm not in a huge rush for the rest of the build, but i'd like to get it working as soon as i have the motor.

    The latest thing posted on the openservodrive site is from several months ago: http://openservodrive.com/ionizer-an...r-stage-board/

    They're saying it's being considered for a DIY board, which is just above my willingness to bother with. I'm not entirely sure if they ever finished it.

    Well he wrote all that to me in July or August; I'm not sure what the current status of those parts are.

    I don't know if he has a site but I can give you his email. I'll find it when I get home later.

    Hey Guys,
    IONI Pro HC will be able to drive the big MiGe, Lenze and AKM servos to full potential. If you intend using those servos, and make use of the full torque, get IONI Pro HC, otherwise the standard or Pro would be fine (for most people)

    When I visited Tero of Granite Devices in September, we discussed forward development of these controllers for FFB wheels, and I suspect IONIZER will not be developed - no need, as Pro HC will be more than capable, plus, there are heaps of other points I have discussed with Tero on where to go with this....

    Suffice it to say, there are big changes coming, I will feedback in the next week or 2.

    edit:I have also added 1x Cube diagram to the first page, thanx all!

    Cheers,
    Beano

    Good news then! Thanks for the heads up.

    Can you tell, at some point there will be no need to use the Disco board (IONI will do both - driving servo and acting as FFB controller) or that won't change?
    Do you have any contact with MMO? I'm asking, because I heard the software don't support rF2's soft lock request - the sim soft locks wheel range to the selected car and that seems to not work with OSW.

    Confim it doesn't work.
    Not a big deal if you ask me, since I record MMOs profiles for any rF2 car with different filtering AND Steering lock.
    Those profiles could be loaded/changed even during an rF2 session.

    OK, good there's a work around for it. Still though, I think it would be better to handle it back to the sim.

    [bb]UPDATE - TERO is running IONI Pro HC - 9 Dec 2015[/b]
    Hey All,
    Just had a nice email from Tero.

    During this past weekend, Tero and Aki had a first test-run of their MMos DIY wheel - yeay, lots of good things to come!!

    They were so eager, fitted a wheel-rim, albeit on a very nice hub Aki has quickly done on the inhouse machinery. The hardware is based on the Disco board, MMos FW and IONI Pro HC. The servo has a Sin/Cos encoder and a is a scary 36 Nm (peak) motor.





    Tero very quickly prototyped few ideas in firmware level (I can see a lot more of this coming very soon, I will follow up with another post, hopefully tonight, about recent discussions we had in Finland)

    -Encoder output from IONI GPO pins routed to the Disco, this could give sin/cos resolution advantage to the Disco. However the first implementation has too much jitter in quadrature output which is pretty much negating the benefits - more work on this will be done

    -Effects (spring, friction, damping, inertia) calculation ported to IONI. This immediately made an improvement over MMos, and will be fine-tuned
    Tero is still not fully familiar with MMos' filter principles, but at least it's friction and inertia effects seemed a bit odd, he feels. Friction looks like "viscous damping" and inertia effect is very weird: at slow wheel speeds it resists movement, and at any higher speed it boosts it. However it may be, Tero will implement those functions directly to IONI to reduce latencies on those filters.

    See Tero's video where he is testing his version, implemented directly on IONI:
    https://youtu.be/KRt6gOg8Z3U

    The reason why a lot of these effects and functions will move over to the IONI itself: If the simulator update rate is 60 or 120 Hz and all post processing is done on the IONI controller hardware, there should be no need for going above that update rate from USB. It should not make any difference in sending setpoints at 1kHz if it would just repeat same setpoint many times before the simulator gives a new value.

    The above scenario of course only applies directly to the IONI. Of course, this is the fun-part of DIY DD FFB: We have a great drive-controller developer working very closely with the community, to improve and implement sim-specific functions directly onto the controller, to reduce latencies.

    Tero will implement and test many things after our recent discussions, some will work, others won't, but the end result will be a very good and stable, low-cost powerful motor controller, which will allow you to select the motor of your choosing.

    This here is a watershed moment for us, and we can expect rapid progress in this arena.

    Will keep you posted with more.
    Cheers,
    Beano

    Thank you Spin, exactly the reason why I luv a wheel with high-torque. It is not for everyone, but if you want to emulate those cars, you need to get as close to 1:1 torque ratio as possible

    Cheers,
    Beano

    Project BruteForce2 - IONI-based DIY DD FFB Wheel

    Hi Beano, hows things-
    Just lurking around forums and saw you here- great freaking project this. I am loving rf2 been racing here for the past 4 weeks - got the new encoder and switched to 20k in mmos and 5k in granite Sw. Felt the difference- dec20th is my 1 year anniversary since i start using osw- and its still running strong. Thanks to you and everyone in the community.
    Peace
    Marcus

    Hey Marcus,
    What a nice surprise It has been a while, hope all is well, Bud?

    Yes, I am not that often here, I should visit a lot more as this is a very nice community with highly constructive feedback!

    We should catch up and have a good chat, I miss you on our chats, would be great to see how things are. I have celebrated my MMos wheel a few months ago too, I cannot believe it is more than a year ago I started Bruteforce threads over at iRacing. How time flies, unbelievable.

    Anyway, I am off to Tokyo and Seoul for a week, I will be in touch though via forums. Let's talk soon.

    Take care!

    Beano

    Amazing dedication Beano[emoji4], I Know right time flies when you having fun, felt like yesterday I just finished the built.
    Safe flight- safe travel bud. Give rf2 a go when you have spare time, I am honestly in love with its track and tyre dynamic especially in race.
    Cheers,
    Marcus

    Hi, just got an OSW (small Mige + Ioni pro), the behavior is strange, FFB seems to be inverted, VERY strong and exiting pits is impossible, the car wants to turn the other way...
    Is there any magic setting for rf2 ?
    BTW the OSW is ok in iRacing and AC, but in GSCE and R3E no.. maybe because they all use directx input

    cheers
    Nicola
