Black Box Goals

Hi,

Please add anything else that may be of use. I hope to be checking-
off these items in the coming months as they are completed. With luck
all will be included.

Black Box Goals:

Hardware Goals:

(1) 1 to 4 axis. Individual plug-in axis cards.
(2) Plug-in I/O card.
(3) Serial PC interface.
(4) 65,536 evenly spaced speeds. No jitter, Scalable up to MHz range.
(5) 1 kHz update rate (motion and I/O).
(6) 8 general purpose outputs (TTL level, LED indicator)
(7) 8 general purpose inputs (TTL level, LED indicator, PC readable)
(8) CW, CCW limit switch inputs per axis.
(9) 2 8-bit A to D inputs (joystick jog?).
(10) Handshake I/O. "Done" output, "Go" input for external hardware.
(11) Flash-ROM microcomputer. Make your own improvements.
(12) Small, cheap, and open architecture.

Software Goals:

(1) G-Code and "other" interface.
(2) All axies equal and independent. All can run simultaneously.
(3) Any 2 axis linear and circular interpolation.
(4) 32-bit absolute position range.
(5) Continuous path or single segment moves.
(6) Linear, S-shaped, parabolic, etc. acceleration profiles.
(7) Constant path velocity along arcs and line segments.
(8) PC readable on-the-fly axies positions.
(9) Pause capability. Decel to stop, wait for OK, accel and continue.
(10) Gear 1 or more axies to any other axies. Any ratio per axis.
(11) Homing routine.
(12) Open source code. Make your own improvements.
