Lulzbot Mini 1 Leveling sounds like a cracking

Hi everyone I have a Lulzbot Mini 1 and I bought a head tool of s=SL 0.25mm with a universal adapter for the tool head. Everything works fine but when my computer connects to the mini and starts to level it makes a weird sound as if getting stuck with something. I see in my computer printing in 1 percent but it then says Printer Error printer encountered an error, connection lost. I Updated the firmware as well any help would help.
