4. Gantry

The gantry comes pre-assembled with printed parts in PLA that are for transportation only. Please remove these parts and replace them with your own, printed parts as you see fit.

All LDO rails are from factory, and should also be cleaned and lubricated. It is also adviced to verify MGN12 Y rails for proper aligment using the MGN12 alignment tool.

Placeholder parts

The Mellow VzBot kits come with placeholder printed parts on the gantry which allow the gantry to be shipped as a complete assembly. These parts need replacing with your own printed parts. Further instructions can be found on the placeholder parts page.
