    Can you please post pictures of all of your settings and also outline what hardware is being used.

    The hardware I use is the following, practically the same here: (SMC3Utils v1.01 - tool - Arduino code - SMC3.ino - https://goo.gl/adkztn) and I followed this procedure for the assembly and parameterization.

    After a few tests the engines moved 1/4 of a turn in the opposite direction of each other, but nothing more. Captura de ecrã 2022-01-09 183624.png

    The pot line needs to be in the middle when the motor is in its at rest position, are yours?

    Sorry, the pot line in SMC3 is green, it should be in the middle of the SMC3 graph when the motors are in their rest position (rig is level).

    Hello I inverted the 5V and GND cables on the potentiometer and on motor 1 the green line is in the center, but on motor 2 and 3 it is a little deviated, what can I do to align them? Captura de ecrã 2022-01-10 122607.png Captura de ecrã 2022-01-10 122657.png

    With the motor in its rest position loosen the coupling connecting the motor to the pot, turn the pot until the green line is in the middle, then re-tighten the coupling.

    Thanks the lines of the 3 engines are aligned, I increase PWmMax but they don't move, can I launch simtolls with the game?

    SMC3 must be properly configured and working as expected before you mess with SimTools.

    SimTools can be configured to launch at Windows startup.

    The green lines are all aligned, I set Kp at 400 and then I go up PWmMAX little by little but the motors don't move. What could be going on so that the engines don't move?

    Will the cable I solder to the brush connect to the ground of the power outlet?

    I have already disconnected the motor body insulation, positive at fast speed, but I still have the problem that when I turn on the current one motor starts and does not stop. the other does not move.
    SMC3utils looks like this:
