    Hello everyone,
    My motor finally arrived(JGB37-540B) and i tried building the FFB according to those videos .However i am not able to get the wheel to work as it should.Spinning the motor on one direction it's more difficult than the other,the board sends some resistance for some reason.When spinning the direction which doesn't have any resistance,one light on the VNH board lights up,when spinning on the direction which has resistance, no lights come up.Inverting the output changes the direction which is more difficult to spin.Some time it stops at the end stops,other times it starts spinning endlessly until i unplug the controller.Any tips?
    I am using two 5k resistors and a BC337 wired like the schematic in the video.

    This is not EMC. It's aiwave2014 with pwm+dir mode of control here with another pins vs EMC. At least may be this. You can pick on test the old version of EMC 0.9 to be sure 100% with this schematics too for pwm dir. Or flash the aiwave itself, if you try this layout with EMC. Also, put on some spring in soft. Otherwise the dir directions will not occure.

    Hi, i was able to get it working on EMC using 1 PWM + 2 DIR.Splitting the direction with the transistor on Ai-wave doesn't seem to work.Maybe my resistors values are not correct.I will keep using EMC for now.
