I reconnect all cables but I have a problem with AR4 moves to the wrong position. Jog command also doesn't work correctly.
It seems that J1 and J3 axis moves with wrong angles. @Chris Annin can you tell me what to check in my AR4 setup?

@Chris Annin I changed the engines.I reconnected the cables.The COM connection on the computer comes the moment I plug in the USB cable, it disappears after a second.The COM connection does not appear in the device manager.That's why I can't connect with the robot.
