J4 Motor gets hot
Hello, I have noticed that J4 motor is hot to touch comparing to J1-J3,J5,J6 motors. Is that normal or something wrong with the motor in my AR4 set up?Even at idle J4 motor is much warmer than other motors

The motors can get fairly warm but if its uncomfortable to touch then I would say its too hot and I would suggest turning down the driver amperage setting and see if that decreases the temperature.
