X-Axis Clone

This project started out as a plotter, then had a router added, which worked out fine, but the moving gantry had some flex in it which reduced its accuracy so I have added an extra cloned motor and lead screw to the X axis. The Arduino CNC shield V3.0 supports this using the spare 'A' socket with a fourth A9844 stepper motor driver board. Two jumpers need to be added to the V3 shield to tell it which axis to clone.

For more information watch the following video...

Parts list

• A9844 driver board.
• 2 jumpers.
• Nema 17 stepper motor.
• Motor mount.
• M6 threaded bar (1 meter) for the lead screw.
• Diameter 5mm to 6mm coupler.
• 6mm thick bras bar for the nut.
• 4mm thick aluminum plate.
• 3mm X 50mm X 3mm thick aluminum angle.
• Various nuts, bolts and screws.

All of my projects are made using only a few simple hand tools and a pistol drill held in a drill press,

also on occasion a DIY CNC machine LOL
