Fix your cheap eBay CNC router/engraver for less than $10. This shield allows you to use the USB to talk to a db25 based CNC machine. What is it? The Arduino G25 Shield combined with an Arduino UNO compatible board running GRBL, allows you to connect a CNC via the db25 LPT parallel port. Why did you make it? I purchased an inexpensive CNC on eBay. The software they recommended was expensive or was free with limitations and was jittery. Moving the processing of the gcode to the Arduino allows for smoother timing that is not based on cpu cycle count. What makes it special? Now to run your CNC all you need is a 'G Code Sender'. Something as simple as a terminal window is enough to send g code commands. What do you get? You get the PCB, male headers and Female db25 right angle connector. This is a kit, you will need to solder the connectors. What you will need... Arduino UNO compatible board USB Cable LPT cable (Female to female like the one that comes with the CNC machine)  'gcode sender application' of your choosing. (If you don't know one, Google it) Use Grbl v0.9 https://github.com/grbl/grbl/wiki/Connecting-Grbl This is a video of the CNC router running on the LPT Port. https://www.youtube.com/watch?v=uZJFjWCpabw  This video shows the same CNC running with the shield. https://www.youtube.com/watch?v=dm-AcufNaw0
