DOF Reality SFU Gearbox Upgrade - Part 2: Assembly Guide

DOF Reality's new SFU gearbox design provides better movement for their motion platforms. In Part 2 we show you how we did the assembly of the new gearboxes to the original motors, the needed electrical modifications and finally the calibration process. This is more of an instructional video so it is longer than usual, PLEASE USE THE TIMECODE LINKS IN THE DESCRIPTION to go directly to the parts you are interested in. This is the second episode in a series that will continue with Part 3, discussing the modifications we made to the H6 to maximize performance of the SFU Gearboxes.

DISCLAIMER: This video documents the process we used to upgrade to the SFU Gearboxes on the DOF Reality H6 Motion Platform. It is NOT intended to replace the official DOF Assembly Instructions. By watching this video you agree to be responsible for any consequences as a result of using this information.
