the cartridge removal of Cart #6, the cart caught on the slitheads (sp1 side). We checked the interlocks and the positions of the axes during the cartridge change. We had encountered earlier that the altitude moved about 2 arcminutes, but did not have any cart change problems. In this instance, the altitude also moved ~2 arcminutes (MCP was reading 90:02:45). We tried to relatch Cart 6, but we were unable to engage the latches. During each cartridge change, we followed the protocol of moving the altitude pin and then pushing in an E-stop (usually the South one). We found that putting in the E-stop, the telescope position would jump about 2 arcminutes in altitude, according to the MCP window. We tried moving the hand paddle to manual mode and repeat latching/unlatching the Cart, but this also failed. At this point, the altitude pin was now stuck. We then tried to move the counterweights to make the telescope bottom heavy and align the telescope as close to 90 degrees again and try to free the alt pin. The cart was still catching on the slithead on the telescope (again, SP1 side). We called Joe at 07:00Z for help. He came out to the site and inspected the problem. Joe was able to get the cartridge to release from the telescope. The wind baffle and telescope are slightly out of alignment. We will cautiously do all cart changes for the remainder of the night. A total of 90 minutes was lost to this problem.
