Major Frame Type

Selected - Mobile gantry design (XYZ all linked) allows tremendous scaling potential.

Mobile bed (X alone, YZ linked) requires a greater non-axis frame to support both X and YZ; scales ineffectively.

Minor Frame Type

Selected - Blocks on plate (Non-axis frame is a plate; X axis begins with 4 blocks on this plate)

Axis Drive

Selected - Stepper motors provide high resolution in a simple open-loop system

AC or DC motors with encoders necessitate complex closed-loop control systems

Spindle Drive
