Stepper Motor – NEMA 17……………… Amazon / Banggood / AliExpress.You can get the components needed for this project from the links below:
For powering everything we need 12V power supply with minimum current rate of 3A. This pin is PWM capable so we can control the intensity of the laser with it. The steppers motors go right above the drivers and the limit switches which are Normally Closed with two wires go at the endstops S and – pins for each axis respectively.įor controlling the laser module, we will use the pin D9 which in a 3D printer setup is used for controlling a fan.
