Pololu Stepper w/Vreg Driver

thingiverse

This homemade PCB, based on Tinkering's design (http://www.thingiverse.com/thing:4526), employs the Pololu stepper motor driver (http://www.robotshop.com/pololu-8v-35v-2a-single-bipolar-stepper-motor-driver-w-regulators.html) and omits endstop connections and LEDs for now. Designed for easy at-home etching via the laser printer method, it's perfect if you want micro-stepping (1/16) or to create your own PCB. To etch, clean the PCB with steel wool and avoid fingerprints. Print the PDF design on glossy paper using a laser printer, iron the paper onto the PCB, submerge in water, and carefully remove the paper when the circuitry is visible. Soak the PCB in an etching solution until exposed copper disappears. Drill holes with carbide tips, clean off toner with acetone and steel wool, and solder components, ensuring proper capacitor direction. Use a multi-meter and magnifying glass to check for shorts before testing the finished board. A complete guide is coming soon!
