Parallel Port Pinout (?): (from http://www.machsupport.com/forum/index.php?action=dlattach;topic=1319.0;attach=891)

1............... M3 OUTPUT (LOW=ON, PULSE FOR PWM)
2…………………………................. A AXIS (quadrature)
3……………………………............. A AXIS (quadrature)
4.……………………………............ Y AXIS (quadrature)
5.……………………………............ Y AXIS (quadrature)
6.…………………………….............X AXIS (quadrature)
7……………………………............. X AXIS (quadrature)
8..……………………………........... Z AXIS (quadrature)
9...…………………………….......... Z AXIS (quadrature)
Pin 10. INPUT, MOVE ENABLE (LOW=NORMAL OPERATION, HIGH=STOP)
Pin 16. OUTPUTS, DISABLE POWER TO MOTORS (LOW = NORMAL, HIGH = DISABLE)
Pin 17. OUTPUT, RESET CONTROLLER (LOW=RESET, HIGH=NORMAL)

Another pinout, "setptype = user1" (confusingly not labled MAXNC10) http://www.super-tech.com/root/drawings/gif/SuperCam_pinouts.gif (from http://www.super-tech.com/root/drawings/gif/Supe

This guy rebuilt his, has derogatory things to say: http://hans-w.com/cnc.htm

This other guy has some interesting upgrades. Especially notable is the new motor mount, and appropriate dxf http://www.timeguy.com/cradek/cnc/motor-mount

User:seph was hacking on one. Some notes from him are at http://www.directionless.org/tmp/maxnc/ There's a pinout, and an emc2 config. He also recommends thinking about eventually upgrading a lot of the components.

OK, got a definitive pinout, seem to conform to those above. Jtfoote 23:11, 28 September 2009 (PDT)
