''Assembly Instructions''

The DIY CNC Controller is a Unipolar Stepper motor controller based on the [[SLA7078MPR]] by [http://www.allegromicro.com/ Allegro Microsystems]. It was designed to be inexpensive and easily assembled by those even with a beginner skill level. The motor driver chip provides excellent power output for driving [[NEMA 23]] and even some [[NEMA 34]] motors. The power output is adjustable between 1-3 amps, with microstepping levels between 1/1 (full steps) and 1/16 microsteps. The board can accept a voltage range between 12-44 volts DC, but 24-36 volts is recommended. The board utilizes an IDC26 connector for easy connecting to a DB-25 ribbon cable, or directly to a [[SmoothStepper]] board.
