have a restriction with the movement of J4, when I go to -86, the cable hits the pulley and a collision is detected. I have checked my installation and everything looks according to the manual, I can't find what the problem is but I still have a long way to go to reach the movement limit, which is 164. To solve the problem temporarily, I limited the movement in the calibration box to -86.55 and step limit to 3300 Original values to j4

Hi, everyone, My robot has been working without problems, but since yesterday I cannot calibrate and this message appears. I loaded the program in the teensy again but the problem persists. I appreciate your help
