We order our bits from precisebits.com. We like their quality and their technical staff was always friendly an helpful.
Collet Adapter The tool we use only holds 1/4" tool so this allows us to use 1/8" tools.

- 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
