I'm building a small 2-axis CNC machine. For this purpose I want to use parts from an old Makerbot 3D printer. I've taken out the stepper motors and they're working perfectly with an Arduino and an external driver.
However I want to reuse the drivers that come with the makerbot to run the stepper motor. As you can see in the picture there's a socket for power, one for the Stepper connection and the wires coming out are what connect with the motherboard of the printer. I want to use these to connect with the Arduino instead somehow. Any idea how I should go about this?
