Hi, I have a kossel with a J-Head style hot end. There are two screws that take a hexagonal bit that fasted the thermoresistor to the hot end. My problem is that I think one of them is stripped and so i can't get it out. These screws are inside the block, so I don't know of any methods to get it out. I tried using some super glue to the bit but it didn't work.by def_pri_pub - Reprappers
