I have been working on setting up the program for the arm to move. However, since last week J4 driver is flashing at certain movements. Normally, it starts flashing before or after a arc movement. I tried testing the arm by creating a loop of random movements and the driver did not flash. Then, when I starting adding the movements from the program that has the arc, joint 4 starts moving on itself. Right now we are cheking if it is a mechanical issue, or a connection issue. Is it possible that the problem comes with the program or the movements that I established?. Right now, I am trying to figure out if the driver is flashing due to a motor or connectivity issue?
