This is Part 1 of the Mantis 9 build instructions. Part 1 takes you through assembly of the X, Y, and Z axes.
Jump to Part 2 for motor/leadscrew installation and final assembly...
When countersinking the rear plate, countersink the side opposite the Mantis logo (ie: the back).
Grinding the Z axis rods is no longer recommended. You can just skip this step.
Tests have shown that grinding the Z axis rods does not improve their resistance to rotation as previously thought.
