WorkHorse 3D Printer X-Carriage Design

The Workhorse Gantry and Carriage design is a heavy-duty solution for lead screw/ball screw motion. I have a newer design that's a little lighter but I haven't tested it out yet.

X-Carriage Assembly

X and Y-Carriages use 4 M3x6mm Screws

• X-Carriage (X-Axis) 2pcs

• Y-Carriage (Y-Axis) 1pc

• M3x6mm Screws 12pcs (4 for each Carriage)

The x-axis carriage screws down to the 2040 Y-axis extrusion and rail. *Note* The y-axis 2040 extrusion must have hand tapped M5 threaded holes.

Linear Rails

The Workhorse Printer uses MGN12H linear rails with a 20mm x 20mm Hole Pattern.

Igus Lead Screw Drive Mechanism

• Reduced the weight and footprint of the Y-Axis Carriage.
• Experimenting with Igus anti backlash lead screw nuts.
• Trying out different direct drive extruder designs

I'm considering making the X and Y-axis C-Carriage designs from solid rectangular bar instead 2" x 4" aluminum tubing. There will be a increase in wasted and machine time but the over all weight and footprint will decrease. The more compact design will allow faster printing speeds due to reduced deflection within the system.
