It is used by design professionals and hobbyists worldwide, for creating a wide variety of graphics such as illustrations, icons, logos, diagrams, maps and web graphics. Inkscape is professional quality vector graphics software which runs on Windows, Mac OS X and Linux. To make gcode files that are compatible with this cnc machine you have to use the Inkscape. Press the "Run on Arduino" button and program your board from your browser! If don't, change penUp and penDown variables that controlling the servo motor. ![]() In this part you will see your pen goes up. ![]() Here is the main CNC code embedded using codebender! If you see any movement here that means that the stepper motors wiring is correct! Here is the X and Y axis testing code embedded using codebender! On mine cnc, X axis motor connection are: L293 A: Pins 1 and 3 & B: 2 and 4, but on Y axis motor connection are A: 1 and 2 & B: 3 and 4. If yours steppers doesn't work properly you must find correct working combination by changing the cables between them and the L293D ICs. On next step you will find a 'testing' code for x and y axis. Steppers motors wiring is something that need patient. Watch the above image with breadboard circuit schematic. Now that we have our contraction ready, it's time to build the circuit and test stepper motors (X and Y axis). Dremel) (Optional for cutting plastic parts) ***Why to use screw terminal connectors? Because you don't want to solder and desolder cables from stepper motors until you find the correct working combination. **USB to Serial adapter will allow the circuit to communicate with the computer through the USB cable, just like Arduino uno does. *You will need also an Arduino UNO board to program the ATmega328 micro possessor
