CNC machine from PC parts - Hack a Day

CNC machine from PC parts

[Mike Rankin] built a small CNC machine using some PC parts. He repurposed two optical drives and a floppy drive to create the plotter seen drawing the Hackaday logo above. The X and Y axes use the stepper motor controlled read heads from two optical drives. The Z axis is built using the read head hardware from a floppy drive. A 3-axis controller module from eBay drives the little machine, keeping the cost quite low at around $45.

As you can see in the video after the break it does a great job as a plotter. [Mike] doesn’t think there’s enough power in the hardware to be used as a mill. We’d still like to try adding a flexible shaft rotary tool and see if this could mill some rudimentary PCBs, but maybe you need to shell out just a little bit more for that functionality. It might also be possible to use an etchant resist marker instead of toner transfer or photo-resist.

Wow! That is really amazing!:) How did he figure out how to re-control those DVD Drives to Draw!???
