I hope this is the right forum category to post this and that the links are ok.

In case you’re not familiar with FFB wheels the game used determines a torque output based on what happens in the game and your steering wheel position, basicly simulating what you would feel through the steering wheel in a real car. For example, the creator of the FFB controller told me that a stepper driver might need a “torque mode” for it to work (can’t find a lot of info about that either though). I’d like to know what to look for in a stepper driver apart from the right amp/voltage rating for the motor used. The missing link here (apart from an encoder to send the wheel position to the PC) being a stepper driver, which I know nothing about. I’d like to use that controller to power a stepper motor like this: I found a controller which translates the games ffb output through USB to a PWM signal here (in German though): So to keep the price down I’m looking at steppers, which are also used in the AccuForce direct-drive wheel, so in theory it should be possible. The OSW uses a servo motor and costs around € 1.000,- in total to build. Generally Sparkfun has excellent tutorials (and often Fritzing parts) for their stuff.I’m looking into building a direct-drive FFB wheel like the OSW, but on a budget. If you post the Fritzing sketch of your hook up I expect one of us would point out any problems we see.Įdit: reading further down the data on the board there is also a current limiting pot, if that is set to less current than your motor needs to operate that would also cause no operation very likely.Įdit2: I got this information from the Sparkfun hookup guide available here If enable is high the fets are off and nothing will happen, if sleep is low same thing (fets are off, motor does nothing).

When you say “doesn’t work” that does that mean? Nothing at all happens with the motors? I’d check the state of the enable and sleep pins. idea is to use a touch screen interface to select boom sections and the location I want them to travel to.Īny hardware suggestions for the drivers?Ī quick look at the bigeasy says it should be easy to use. I intend to control the motors based on distance to travel. there is only one endstop which is for the nema 8. the motors work when connected directly to my mega board but not to the driver. I have a big easy driver but for some reason I can’t get it to work. I need to select hardware to control these motors. My own Fritzing parts repository, ready to be used. I have the idea of how I want to achieve the mechanisation of the telescopic boom.ġ_ 2 x micro steppers to control the retraction of a locking pin, the motors work simultaneously in parallelĢ_ 2 x micro steppers to control locking pins to pick up the boom section, the motors work simultaneously in parallelģ_ 1 x nema 8 to control the carrier that hitches to the boom section and moves it. I am a beginner and have a large RC Crane project on my desk.
