I fixed the Z-Axis Rods and added it to the instructions.

I put Blue Loctite 242 on the screws for the limit. You have to be careful not to get any on switch it can eat the plastic. I'd like to move it in the future to allow me to easily set my Z-offset.

I also made a test print in ABS, it came out very well for a $200 ish dollar printer.
