Installation

Step-5: Clean the printed mount and ensure correct hole sizes.

Step-7: Screw the mount to the print head plate using the holes of the original fan metal frame and with the M3 x 8mm screws

Step-8: Install the X endstop sensor

Step-9: Install the hotend (don't forget to reinstall the PTFE tube as well)
