[1] If you study the predefined GRBL pin-outs in photo 2 you will see that none of the PWM (pulse width modulation) pins are available for controlling a servo. If I set the Homing seek ($20) in GRBL to 200 mm/min the X and Y axis appear to move just fine, but the Z stepper stutters, and doesn’t rotate smoothly. Project how to build a Mini CNC plotter with 2 old DVD players (stepper motor), Arduino and 2x L293D drivers. For the Z-axis, since one cannot do holes on a 3-axis machine, the best thing to do is to mill steps and measure their height. It’s noted that this configuration could even be used as a CNC router if a rotary tool and Z-axis was added. This could make things a bit less difficult to find the most ideal tool for the job. Grbl is a free, open source, high performance software for controlling the motion of machines that move, that make things, or that make things move, and will run on a straight Arduino.
