Argon Small Mige FFB not working

I have a question regarding (product) regarding (issue).

My hardware configuration:
-Mige 130ST-M10010
-Latest FW

Problems arise when:
-Made a mess for myself and thought that Simucube software should work on an Argon drive, managed to flash the argon and load SC FW on the drive,which didn’t work, idiot me, even said with big red letters that the Simucube didn’t work on the argon drive. Anyways.
After much faffing around I’ve managed to get everything flushed and loaded the proper Firmware for the Argon and the Disco board, so now the Argon firmware is on and read by Granity, and the correct MMoS firmware is loaded on the disco board. Managed to source a drc file for the motor, and set that up, all settings double checked by Tomo from SimRacingBay.

How it behaves:
-Wheel turns on and phases as expected, can center wheel and get offset value in Mmos, loading up RRE, can set axis and wheel will turn, but the FFB will not work, and wheel gets very notchy and heavy to turn when ingame, its like I have to force it over big tops, and then falls down into next valley for then needing to be forced over next top again.

I’m at loss to what it is, have searched all over internet, and can’t find anyone with the same experience.

I have attached following files:
I am getting these faults in Granity, but don’t know what to read of them

Granity%20fault%201 Granity%20fault%202
-(consider adding saved Granity configuration file .drc)

Thanks for any help you can give
Best regards

does the wheel rotation match the Position Feedback and your Counts Per Revolution (4*PPR) value in Granity?

Hi Mika

Thank you for your quick reply

I’m also getting this fault message when I try to turn the wheel to check the position feedback

And the wheel disconnects from Granity

After carefully turning my wheel 360 degrees, I got a reading of 20.000 on my position feedback

there might be some interference affecting the Argon connection, I can’t see any other reason that explains it.

It is a strange one, wheels been working flawless until I stupidly tried to install simucube on it.
Other than that, nothing is changed, what type of interference can cause something like this?

wrong settings in the MMOS for the feedback PPR value, perhaps. If you have 5000 PPR (20000 CPR) resolution in Granity, then MMOS should have 20000.

As far as I know the motor is a 10000 ppr, and that has been the setting used in mmos until i messed it up.

Settings today is 10000 ppr in granity and 40000 cpr in mmos.

I can try with 5000 ppr and 20000 cpr and what results I get.

Will this explain the strange ffb behavior?

The FFB will feel horrible if you have a 10k ppr and have the settings loaded as 5k.

Don’t forget that you have to change the settings on the hardware tab in Granity to the correct setting 10k in this example.
MMOS will be to be set at 40k

Also be sure to try to get the offset number that you see at the top of the screen in MMOS to be + - 1000 in MMOS or the wheel might act oddly.

It is very possible that you may have to turn the wheel a revolution or more to achieve this since you have reflashed everything and likely have rotated the wheel before getting MMOS properly set up.

Hi Joe

Thanks for trying to help.

Settings in both Granity and MMos is set correct for 10k ppr, Mmos is showing offset around -70 when centering.

Thats the odd thing about this, everything seems to be correct, but theres still something not working.

Next thing that might be an option would be doing a factory reset of all the components and then reintroduce the firmwares, but I don’t know how to do that. Or if its possible?

I would try updating the Argon software again.

To be totally honest I would have to read the instructions on how to do it. I have not done one in a few years.

Was the drc that you used for the Argon?

I will dig thru my old files and see if I still have a copy.

I’ve been using a drc for a 5000 ppr argon device I got from Tomo, and changed ppr setting in Granity. Would really appreciate it if someone could manage to get a correct file for me to try.


FW 2.1, 10K encoder, small Mige, 110v.

Thanks, I’ll give it a try, I’m on 230V tho, but should be enough to just change voltage in Granity after loading.

[FOV] and [FUV] found under the Fault Limits. exact values should be suggested on help page.
2.1 FW is here
Make sure to get simulator wheel build

Don’t know whats going on here, I get the wheel to work, but FFB is weak, and there is no self alligning torque, in addition the wheel feels sligthly notchy.

I’m using your DRC with the voltages corrected Andrew. By the way, thank you very much for trying to help out here.
