Arduino lead screwdriver to partially automate a table saw jog #Arduino

NewImage

Thanks to Jim for sending in his project! Check out more info here.

I constructed an Arduino based controller to automate the carriage on my lead screw Box Joint Jig which was originally inspired by Matthias Wandel at woodgears.ca. Interestingly, Matthias added automated operation by a laptop to his design at the beginning but later removed the function in favor of multiple wooden gear sets. My jig was manual at first and automated later after I kept losing count of the crank turns…

I used an inexpensive DC motor driven with a Polou MD01B H bridge, and added position feedback to the lead screw. This gear drive motor from All Electronics (DCM-697), was intended for actuating automotive power seats. I sawed the shroud off the connector housing so I could use standard push on terminals. The mounting base is a bit of hardwood flooring rounded out to fit the motor and hose clamped on. I can loosen the clamps and slide the motor to align the sprocket and adjust the chain.
