The smoothest most perfect cnc "HAND CONTROL"

I Started out with a microsoft sidewinder joystick(gameport), Kinda
large, bulky and hard to hold and steer. It was precise and
controllable. Looking at the number feedback from Analog-digital
conversion, no noise.

Then, Gravis Gamepad, Noisy, junk (soundport)
Then, AAC gamepad (analog into soundport)
Then, Gamecube controller purchased @ Radio shack (blowed it up
hacking)

Then, Sony Play-station-2 replacement dual joystick, purchased a
SMARTJOY adapter to convert it to USB. Plugged it in, windows grabbed
it's image right off. Linux I have not figured out yet.

STEADY and SURPRISING.. Watching the numbers with resolution set to
10,000 it don't click a single number. 9 buttons I have figured out.
Two joysticks, plus a POINT of VIEW hat I have hacked out.

I will post the Visual basic code on the DIY-CNC site later today
when I get back on the WIndows machine.
It'd sure be nice to include that with the EMC. I think, this is the
most common controller on earth. Play station two..
Hacking it for robot control was done originally by Nuts and Volts,
I was referred to that issue by a helpful member here.
Anyone pretty good at PIC programming could do a cpu translator to
Pulse and direction.
I'm still learning C++, not that good at visual basic but really
stubborn. This example uses DirectX8. It has simple calls to initiate
and configure the joystick, "it would work with most other usb
joysticks" as long as you have directX.

EVEN though a cnc machine should work by g-code, using one to spot
drill like I do, cut simple grooves and "Free-cut" is still the
easiest.

Which "purchased software inputs a joystick?" I have some I wrote
using a 8255 driver but have not gotten the accell-decell right yet.
Now that I have figured out directX, it has a timer you can call.
Plus, screen drawing by 3axis.X files that are the most compact I
have ever saw, and rotation of models and lines by Camera point of
view. (use the hat?) Surfacing by simple wrap commands. If I ever get
time, it will be the neatest modeling input tool ever..
