Interface between PC and stepper motor is G-CODE.

Logo is drawn in black and white in Inkscape (that is a vector drawing software). An Inkscape plugin transform graphics in G-CODE (line by line scan). G-CODE is sent to a microcontroller (arduino pro-mini) via USB-Serial and arduino controls two stepper via LM293 H-Bridge driver.

Arduino program is hand written, it support basic G-CODE for G0-G1 I could not use adruino GRBL library because it does not support arduino pro mini and h-bridge.
