Hi All, I have come into inheritance of a UR3. It seems in good condition, however there’s one thing wrong: joint 3 (elbow) is at \>180 degrees. This means it can only rotate up to 359 degrees. If I try to go below 180 degrees the wrist joints clash with the base. This limits my possible movements a lot. How can I go about remedying this? I have come across [this topic](https://forum.universal-robots.com/t/axis-3-absolute-position-offset-by-360deg-after-power-loss/18694)that seems to be the same thing, however following the steps of deleing _.urcontrol/.last\_seen\_joint\_positions.conf_ has not changed anything. Thanks! ---

Solved - sort of. I spent a lot of time messing around with the _.last\_seen\_joint\_positions.conf_ file, but nothing seemed to work. Instead, I jogged the joint to ~200 deg (with the arm on), removed the joint cover, manually pressed the brake down and moved the joint through to ~520 deg, and upon turning on the robot arm again and verifying the arm’s pose it assumed the arm was at ~160 deg; fixing my problem. I would be interested in knowing why manipulating the files via FTP did not work, and I had to resort to surgery.
