So I found the connection where the z touch puck goes into the machine was very loose. I tightened that and now my z axis goes up and down much better( still sounds a bit weird) but it does not home it self, it goes to home in the x and y axis but the z continues to go up, then down, then up...like its lost or something? Do I need to "reboot" it or something? I put in a call to technical support on Thursday, didn't hear back from them, got an email saying they were busy and that they would get in touch with me I Friday..nothing. Hopefully they get with me on Monday.
