Build in 'Cartesian Style Bots' published by Tim Pierce, Jun 20, 2016.
This project shows how to use Openbuilds Vv slot extrusions and wheels to retrofit a Lulzbot Taz 4 or 5 printer. These modifications improve layer consistency, eliminate nozzle and bed sag, and allow for larger toolhead mounting.
