DIY FFB Steering wheel (MMosFFB ) (In Progress)

Yeah, just run everything in parallel, but try to keep the main power wires as close to the same length as you can. The logic wires are not so important. I have been running mine faultless for 3 years.

A second word of advice - Even though your heatsink is cool, the chips on the other side might still be hot. There is poor connection between the board and the heatsink. Ideally, you need to add solder to the vias (holes) behind the chips (under the heatsink) as most of them will be empty and gives poor thermal transfer. Further to that, add some heatsink pad between the PCB and heatsink to help get the heat away. This helps them last a lot longer and increases current handling.

I experienced a similar situation, after changing to a more powerful Psu, the issue was resolved.

Cheers guys! going to get a bigger PSU as this makes a lot of sense

You may want to consider a higher current but lower voltage power supply if that's the case. Running too much power will want to fuse the windings.

There are some great calculations that another member has done somewhere on here to do with efficiency of the motors and expected energy to be given off as heat to determine the ideal limits.

Remember, just because your motor might be rated at 1000W, that's not in stall mode. Stall mode means that almost all energy the motor consumes is given off as heat rather than rotational energy. From memory it was only about 30% of the rated wattage that should actually be used (sustained). This can be controlled by setting the max % output in EMC. A high current clamp meter is a good investment to keep things in check.

Hello i am having a problem with my diy steering wheel i built. im using arduino leonardo and emc lite, everything works perfect in emc and I can turn the wheel and it shows the wheel degrees prefectly, but as soon as I load any game and there is a car it immediately stops working correctly and the steering rate goes down and it steers very slow and eventually stops working unless I close the game then it instantly works just fine again. i have absolutely no clue why this is happening and would appreciate help.

Can you describe more about the hardware?
Motor:
Power Supply:

What game are you trying it with? Have you used anything else?

My gut feeling is that it's either power supply related or possibly the game you are using is not compatible with EMC Lite.

Remember, EMC lite has not been developed in many, many years. You're much better off with EMC Pro on an STM32 or look at OpenFFBoard as both of these are current development.

I'm using a 250 watt brushed DC motor and a brushed motor driver which does pwm for the motor and just powered off a battery. And it doesnt matter what game all same results, I have tried beamng, project cars and euro truck sim and all the same. Maybe I'll try EMC full version if that might help.

If that's the case, I think you're going to have to me much more detailed in the description of your setup.

yea I don't know if the problem is even fixable. But I've had times where I would load up a game with the wheel and it worked perfectly the whole time I would play, and other times it doesn't work and currently isn't working. I must have done something to get it to work in the game but I don't know what.
I've followed a tutorial from this video ( ) I have pretty much the same setup except the mechanical hardware is a little different as it uses some 3d printed parts but all electronics including the motor are the same.

well I have found the solution to the problem. apparently all I had to do was connect power to Arduino through the dc jack and now it seems it gives more power to the encoder. I think when a game was running the USB 5v couldn't supply enough power for everything and the encoder, so it started being slow but that might not be true just my theory. but now everything is working as it should the wheel always stays centered and the steering rate is constant at all times.

Hello

I am thinking of mounting a steering wheel with STM32F401CCU6, BTS7960B, 1000ppm encoder. I will use the EMC pro program, which I currently use for a Logitech G27 MOD. As for the engine, I'm still not sure. I have thought about an XD-63120. But I have these two options that I don't know how they can work.

I'm sure someone understands more about engines and can help me.

Sorry for my English as a translator.

Hello everyone, I’m making a steering wheel with my own hands using an arduino leonardo and encountered an error in the RFR Wheel Configuration program - Copyright Ai-Wave 2016 (version 0.21)

Hallo!
I'm Vladimir, new here.
I'm glad I signed up; it wasn't without reason.
I've been working on an Android-based force feedback (FFB) steering wheel for quite some time, collecting various motors. Currently, I have options like 24v 200w +-3000rpm and 80BLD300L2 24V 300W, which comes with a Hall sensor.
My question is, can I directly connect the Hall sensor from the motor to an Arduino to avoid using an encoder?

Hello I'm planning to build DIY sim wheel and pedal. Need a overview on the software and hardware required to do so.

Hi sir plz help me i am using emc lite version in that i have set steering angle to 900degree but when i spins the steering wheel it locks at 450degree plz help me

Half the number of encoder pulses

Wouldn't you double it?

Try it see what happens
