2. Automator | Design Overview
Dimensions: 2.6m x 0.6m x 1.3m
Aluminum T-Slot Extrusion Frame
Wood side paneling (not installed) z y x

3. Automator | Gantry System
X Axis
Carries Y and Z axis gantry systems
Guided by V-wheel carts on aluminum extrusions
Driven by DC motor powered timing belt
Y Axis
Carries Z axis gantry system
1 self aligning sleeve bearing
1 fixed alignment sleeve bearing
Z Axis
Carries build platform handling equipment
Guided by carriage on a linear track

4. Locking feature wears too easily
Automator | Build Platform Features
Clamp-on fixture
Self centering holes for Automator fork
No modification to existing build platform
3D printed
Drop in lever replacement
Extended length and added T for Automator fork
Locking feature wears too easily

5. Automator | Part Remover
Old Design
No space on y axis to insert build platform
Total Y axis actuation length 0.45m
Part remover is too long at 0.50m
New Design
Part remover minimum length now 0.37m
Blade action now behind actuators connected by linkage x y z
