I am having the same issue straight out of the box. Starts printing at 4-5" from bed and makes a bunch of funny noises. I am an engineer and this is my 4th 3D printer so I know to following instructions precisely. Solution?

For the most part it is fixed, I think. But now the print will stop half way through then stop. Answers?

I've been having the same problem with the print stopping - were you ever able to find a solution?

Just an FYI, I was having the same issue and what fixed mine was adjusting the right hand limit switch. I was not making contact at all. Loosen the screw on the housing and squeeze the switch up to meet the carriage bracket, then test the homing again, if it works, tighten the screw back up and you should be good to go.

I had this issue once. It was because of the position of the z-endstops.
