One row:
The Major Components:
Stepper motor — using NEMA 17 Stepper motor (40oz-in –>2.5 pounds) as of now
NEMA 17 Stepper Motor 40 oz-in
Motor driver — Was going to use the TLC5940NT’s I have from before, and just add H-bridges, but in order to save pins on the arduino boards I’m switching to Easy Drivers.
Arduino — One Arduino Uno to control each row so each motor can be controlled independently. To get around the limited ground pins I’m just going to cut up dupont jumpers and solder them back together in a Y.
