With a typical single port, you have twelve outputs and four inputs: http://www.linuxcnc.org/docview/html//hal_drivers.html#sec:Parport http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EmcKnowledgeBase If you have three axes that are controlled by step and direction, that will take up six outputs. If you are going to use limit and/or home sensors, I think that anywhere from two to nine or more inputs will be needed. So a single port could run a CNC machine, but it might not have all of the features you want. It depends on the details of your design. The assignment of each pin is controlled by what you enter into your .ini file. A Pico Systems or Pluto-P controller would give you more speed and I/O in a single port solution.

Re: [Emc-users] Parrallel Port Breakout Board
Just for info, I made a breakout board using 10k ohm resistors and terminals. I used it to hook up an MPG encoder to the parallel port with selector switches for axis selection and increment. I built it for testing but plan to implement it for a control refit.

Re: [Emc-users] Parrallel Port Breakout Board
yes The documentation for the parallal port is in the Integrators manual... http://www.linuxcnc.org/docview/html//hal_drivers.html#sec:Parport If that is what your asking...

[Emc-users] Parrallel Port Breakout Board
Hi, Does EMC2 still support the use of a single Parallel Port? If so where can I find documentation on the functions handled by a single port system and how this is done?
