FILENAMES: Dfmill.jpg Dfmill2.jpg Dfpcbmill.jpg DESCRIPTION: These are pictures of a home built CNC conversion of a milldrill. Posted by Dan Falck . Dan provided the following description: ========================================================================== Here are some Jpegs of my garage CNC.  I put it together with parts bought and salvaged over the last couple of years.  I use it to do milling, drilling, and engraving. It is very useful in my shop.  My current project is milling circuit boards for more powerful stepper drives, based on an Ericsson/Kevin Carroll design. I have built and tested one drive card so far and it pushes between 5 and 10 amps, depending on switching a power resistor.  Dfmill.jpg-  a picture of the mill.  It has Superior Electric 300 oz-in stepper motors driving it. Thanks to Dan Mauch for the motors and much encouragement.  Dfmill2.jpg- a picture of the mill, with the computer next to it.  The computer runs Dancam.  The stand that the computer is sitting on is an old Decwriter printer case that now houses the drives and power supply for the CNC. Dfpcbmill.jpg- the mill actually milling a circuit board for the next generation of stepper drives for my shop. I mount the board on a chunk of aluminum with 3M carpet tape.  It seems to work.  I use an engraving cutter to mill the traces and then drill the holes with a solid carbide end mill (.040" diameter).  This system works great. I can design a circuit and have it done in 20 minutes, depending on size.  I have done some R&D for some stuff at work on it. Again, I want to thank Dan Mauch and Kevin Carroll for all the help and encouragement that they have given me over the last couple of years. Dan Falck Nashville, Tn.
