Reinforcements have arrived

To replace the DC motors I ordered three (3Nm 4.2A) stepper motors, drivers and power supply from Longs ebay shop. With their German warehouse the my order arrived within the week.

Later that same day I started connecting every up and I was ready for my first test. For testing I again used my favourite CNC program, LinuxCNC.
