The new E3D hotend is 5.5mm longer than the old Hexagon. We need to make an adjustment to the firmware file so that the printer knows its own total Z axis height and does not crash into the bed or wiping surface.

On line 388 of Configuration.h, change the value of Z_MAX_POS from 159 to 153.5.

The firmware for the mini can be found on the USB stick that came with your printer or directly from Lulzbot's site. It may be easier to download the folder via ftp.

Complete instructions for flashing the firmware can be found on Lulzbot's site.
