  • Built Table (stolen from our old darkroom)
  • Added Ikea lighting fixture
  • Motor screw heads were too large, belt sander + cordless drill milled it down to size
  • Added t-slot rails to board and 1/4-20" bolts with knobs
    • 57715K75 McMasterCarr - 3 Prong Knobs $0.91
    • 1850A11 McMasterCarr - TSlot Tracks 18" $3.99
    • 92865A549 McMasterCarr - 1/4-20" 2" Bolts $8.68
  • Added cable management
  • Added removable Monitor Stand


  • Z Axis

So it turns out most CNC codes operate with the positive Z going up. In order to mill most of the pieces for our machine we needed to chance the scaling to -1 or the machine moves the wrong way.

  • M3 S Code

Apparently our CNC keeps crashing when we run MACH 3, not sure why but it is always on the M3 S Code. We get some error that reads Go SpinCW(). The M3 code is for the spindle spin up. Since our machine doesn't have a relay we just delete these lines of code and we are fine.

  • Driver issues

Apparently when mach 3 crashes it crashes hard. We have had numerous issues where the mach 3 driver seems to hang, the jog commands are unresponsive and the pc blue screens.

Recommendation 1) "You're operating on a laptop, the parallel port's are notorious for going into low power." -We are using a Mini ITX so I was wondering if the same thing was happening. Doesn't seem definitive.

Recommendation 2) Use the drivertest.exe in the mach3 folder -done the pulses seem to flash when the drivers are working and hangs when it's not

Recommendation 3) Run specialdrivers.bat -mweh didn't seem to do anything, seemed even worse so i ran originaldriver.bat, it's working... for now

Recommendation 4) Reinstall Mach3 -tempted, but haven't tried yet
