Re: virtual hand jive

Ballendo,

No, I just want better jog buttons. Not the "virtual" environment. And
as I don't have handwheels on my Sherline, I am simply looking to get
better "jog buttons" for MaxNC or CNCpro (or MY code).

That DOES raise a question, if you did set up on the stock for origin
(with the control program), doesn't that mean that you CAN'T touch the
Sherline's handwheels? You're gonna loose your place on the controller
program's display! They'd only be good if you were NOT using the
controller program! Strictly manual mode. I don't think I want 'em!
Someone suggested putting DRO's (encoders) on the tail shafts of the
stepper motors, that still sounds useful.

I'm not sure yet if I want to do the TSR thing to "translate" encoder
pulses into key codes for the keyboard buffer, but if I do (for programs
that I DON'T have the source code for), then the TSR will probably work
at the same "level" as the INT 9 keyboard interrupt, and the "codes" I
generate are simple ASCII into the BIOS' keyboard buffer at 40:1A &
40:1C (pointers to actual buffer).

If one chooses to "parallel" another (modified) keypad with the existing
keyboard, then scan-codes are sure to apply.


Alan I'll leave the (virtual) hand jive to Eric Clapton for now.
