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.
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.
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.
You get the PCB, male headers and Female db25 right angle connector. This is a kit, you will need to solder the connectors.
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)
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
