Question SMC3: Why can I not turn on the motors?

Hi Guys. I'm new here. XSimulator inspired me to finally build a flight simulator. The frame is ready so far.

The wiring I have taken from this great forum (see picture).
The two H-Bridges 43A you know, I have only remounted the heat sink on the opposite side.

When I press "Motor on" in SMC3Utils, the switch will remain OFF.
The motors remain dead accordingly.
Even if I position the pots in the middle position.
For SMC3 V1.0 I also set "#define MODE2".
Wiring I have also tested several times.

Do you have any idea what I can do?

In the SMC3Utils the green line in the graph should move up and down as you turn the pot by hand. Does it do that?

That was a good hint.
I noticed that the green line was very blurry. After I removed the ground of the electromagnetic shielding I had a much better signal (don´t knwo why, but it´s true).
Know I can switch the Motors on.
Thank you !!!!!!

Hi, are your engines moving now, because I had the same problem for a while. My potentiometer exceeded the max limit, and automatically SMC3 utils cut the motor.

I also look at your wiring in the photos which is different from mine, because today my engines are still motionless.

So I Wonder?

Salut, est ce que tes moteurs bougent maintenant, car j'ai eu le même problème un moment. Mon potentiometre dépassait la limite max , et automatiquement SMC3 utils coupait le moteur.

J'ai regarder aussi ton cablage sur les photos qui est diffèrent du mien, car aujourd'hui mes moteur sont toujours immobiles.

Donc je m'interroge ??

Hi MarcBrochet.
Do the green line gererally move if you turn on your potentiometer?

yes I can navigate up and down graph with my potentiometer, I also see pwm pulses generated (yellow line)

oui je peux naviguer en haut et en bas de graph avec mon potentiometre, je vois aussi des impulsions pwm générées (line jaune)

what intrigues me the most is the fact that R_EN and L_EN are always 0

ce qui m intrigue le plus c'est le fait que R_EN et L_EN sont toujours a 0

Hi Oliver!
I have the same problem with my test. was your motor works?
I do step by step with SMC3 but motor not moving.
I can see the green line (pot) moving when i turning pot by hand
but the yellow line did not moving, im i missing some wired?

Need your help pls

In my case I removed the grounding of the poti-cable at one side (only one side of the shield remain at grounding).

The first thing you should have is a stable potentiometer signal, once it is stable to adjust clip and dead zone if it exceeds those lines it will automatically turn off the engine, it may be necessary to restart arduino to re-select on

That's my problem. it's bad connection pot signal so its alway turn OFF the engine. thanks so much
