    Hi all,
    I've got an issue with SMC3, Motor 2 is the only output that allows the motor to reverse.
    I have an Arduino Leonardo and IBT2 and was wondering if the arduino may be the issue and that I have to use an UNO.

    With a voltmeter, I found out that the Arduino is sending signal to both PWM pin with all 3 motors outputs when the green line is away from the blue one. I can see that the signal in one direction is stronger (mostly 4.57V) than the other (never more than 3-ish volts), which I guess, overlaps the weak signal makes the motor turn in only one direction.

    What I tried:
    - Swap to an Arduino micro board, no change
    - Swap potentiometer, no change
    -Swap IBT2s, no change
    -Swap motors, no change (both motor are wiper motor but have been grounded following the guide on the forum)
    -SMC3 is set to mode2 but mode1 doesn't change anything either
    -SMC3Utilis, everything is set to 0 expect for KP=400, PWMax = 150, Limit and clip = 255

    Has anyone experienced this issue ?
