All I had to do was hard-wire/jumper a small handful of signals and I should be able to control a machine with LinuxCNC.

Having the step and direction signals from the parallel port broken out neatly, I started thinking along the lines of breadboarding up a few DRV8825 modulesвЂ¦ and then realized that was already pretty much done with most any of the common, and very inexpensive, Arduino CNC shields out there.

LinuxCNC (and Mach3) runs on the PC and spews real-time control and timing signals out the PCвЂ™s parallel port pinsвЂ¦ and step and direction signals for each axis is all we really need for basic control of the CNC machine attached to the other end.ДЄfter loading up a junker desktop PC from a LinuxCNC/EMC2 liveCD I had, I found a вЂњMach3 Interface BoardвЂќ (a simple parallel-port breakout board) IвЂ™d picked up somewhere along the way. Over the past few days, working from my PC/CNC/electronics stash/junkbox, IвЂ™ve come up with a very inexpensive, not-too-complex, hardware interface between a LinuxCNC (or Mach3) PCвЂ™s parallel port and MPCNCвЂ¦ or most any machine driven with A4988/DRV8825 вЂњstepstickвЂќ drivers.ДЇor those unfamiliar with these parallel port interfaces, this is purely a hardware interfaceвЂ¦ thereвЂ™s no firmware and/or вЂњsmartsвЂќ needed. Recently, after interacting with a couple of fellow Linux users over in the RCGroups forum, IвЂ™ve had my interest in LinuxCNC rekindledвЂ¦ which IвЂ™d first used when I started in the CNC and foam-cutting game.
