I finished building my AR3 robot and when I tried to calibrate the J1 motor it does not work properly....
It starts to move in the oposite direction of the limit switch and after 1 second, maybe less, it stops and the program says tha J1 is calibrated succesfuly.
J5 is similar to J1, when I click auto calibrate only J5, the motor moves a little and then appears on the screen that calibration is succesfull. the carrier did not even touch the limit swich.
All the others motors calibrate similar to the startup procedure video on youtube: it moves until it reaches the limit switch, then goes in the opposite direction slowly and the slowly reach the limit swich again.
I checked the wires and apparently all the wires are correct.
