I am working on a CNC machine, home made, slow work in progress. I now
use a dremel with a flexy shaft extension. Its hooked to a 5 1/4 floppy
disk drive head carriage assy. I run the stepper up and down and it has
plenty of power to run the setup. I put two hall effect sensors on the
side of the assy and it auto cycles the bit up and down. That keeps the
cycle time (up and down) down. The bit just comes out a little over top
of the board and waits for me to align the bed for the next hole. Then
one push of a foot button and it auto cycles the bit. I have a dollar
store laser pointer that pin points up the drill bit landing point. I
had to add a collet, black cardboard hole punch with a pin prick in it,
to the inside of the pointer screw on lens. It was not quite fine
enough of a laser dot. Helps this blind guy allot. I use SAA 1027s, no
longer made, I had 8 of them in a parts drawer. Im sure any cmos
circuit with 500 ma worth of power would work. It only needs direction,
stop, and clock. So with all that working. I move on to the bed X and
Y driver hardware and control software. I would like to find a gw
basic program ready made or some program that could be patched or
modified by a rookie without allot of trouble if needed. Also, DOS
based, if anyone has an idea here. Hope I don't end up writing my own,
but, Cheap is my standard. And I only make a few boards a month for
personal use.
