Question Sabertooth 2x32 voltage issue

Hello,
I'm testing my new sabertooth 2x32. I configured it on Describe like this:




When I do a test on GameEngine ("Output testing" tab), I have one of my two motors which runs more or less quickly depending on the position of the cursor (while the other motor correctly changes the orientation of the motor ).
When I measure the voltage at the motor terminals of the sabertooth, I always have a value on the motor which turns on its own and on the terminals of the other motor, when the motor arrives at the requested position, the sabertooth cuts the terminals at 0V (which is the logical operation I suppose).

Do you know where my problem could come from?

thank

First I used the code from x-sim.de version 1.6:

I followed this tutorial with its connections:

Like the tutorial, I used an Arduino micro (official).

Then I tried the tutorial here:
https://www.xsimulator.net/communit...ial-pid-motor-driver-sketch-w-softstart.9277/

I used an arduino uno (official) and made the same connections as the tutorial. The code used is that available in the tutorial attachment, SPS_8.2_softstart.zip

On SMC3:
- Motor 1 everything works correctly
- Motor 2 the motor runs continuously. If I turn the potentiometer by hand to reach the target line, it changes direction but maintains its speed. It is continually powered by the sabertooth.

I tried to connect the wires from the M2 motor to my M1 motor, with the P1 potentiometer connected to the arduino instead of the P2 potentiometer: the motor stops correctly when it reaches the target, and the M2A and M2B terminals of the sabertooth are cut to go to 0V.

In conclusion I think my problem comes from the M2 engine. I'm going to take it apart to see if I detect anything.

hi, I checked the connections to the potentiometer and to the arduino, nothing to report. However, I found a contact tab for the motor which was not bent well. I think the current was circulating poorly, there was a false contact. I unsoldered, bent, resoldered. Now, it works correctly on SMC3, motor 2 reacts well!
