I'm using a home-made CNC drill machine,for two years now. It is designed so that it is easy to make.
It is a stand-alone machine, connected to a PC with radio comm.
I'm using it to drill holes in PCB, for makeing holders for mounting LED diodes, and also to cut shapes and letters from softer materials, like plexiglass and XPS(extruded polystyrene).
I'm willing to give complete documentation needed to make this machine with DEMO version of the software for FREE, and a complete version of a software for a price of 150 Euro.
