Question FFB Problem with my wheel

Hello everyone this is my first post here and I need your help.

My wheel works fine at low power but when I increase the ffb above 50% on EMC, it only takes a few moves of the flywheel for the ffb to stop working.

I built my wheel with a Leonardo arduino, a bts7960 motor controller and a mitsumi m36n-5e motor (a motor a little more powerful than a 550 but not as powerful as a 775).
I use the paid version of EMC, version 1.02 witch is the last version compatible with arduino.
I power this thing with a 24V 20A power supply, the type of power supply found on 3D printers so I don’t think the problem come from here.

Should I put two bts 7960 in parallel, or maybe the problem comes from the arduino and I will have to change the board to have the latest version of EMC?

I don't know why this loss of FFB happens I would like your opinion on this. Thanks

Hello there.
I use EMC pro too.
can I look your wheel base setup? what pulley ratio do you use?
If I may give you a suggestion, you should upgrade your motor.
I think your motor torque is too little, and its so hunger of power just like RS motor and its take a lot heat on the BTS 7960.
I use my6812 motor and use a 15T and 110T 3D printed pulley, and only use one BTS 7960.
I think its a standard formula to get a proper FFB and not to overburden the motor.
btw, you can still use your arduino, its not the cause of the loss FFB.

Thanks for your reply.
I attached a picture if you want to see how it looks; it’s based on a Logitech g27. Sorry it's a bit of a mess on the picture, I'm still building it.
The pulley ratio is 1:9.9. I use a 336 mm GT2 belt with a 16T metal pulley and a 158T 3D printed one.
I’ll try to test with a stronger motor to see if it works better. Can I put something more powerful than a my6812 with the bts 7960 or is it the best I can get with my setup ?

thats a nice ratio, and its enough to pair it with bigger motor.
yes you can put bigger motor on bts 7960.
just make sure, you have good cooling fan for the bts

Ok thanks for your answer.
Luckily I managed to disassemble the same DC motor the my6812 from an old electric scooter so it should work perfectly once I have adapted the whole setup.

thats great.
let me know how it works
