Tools

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.

  • 1/4" to 1/8" Collet Adapter ($4.80)

  • 1/16 in. (.0625 in., 1.59 mm) DeepReach Fish-tail End-mill, 2-flute, 0.50 in. max DOC, 1.5 in. OAL
  • We use this for most of our detailed wood work
  • 40 ipm on our machine by default, we've run it to 120ipm with 0.050" depth per pass

Tool 2

  • MM208-1250-113FL $28.88
  • 1/8 in. (0.125 in, 3.18 mm) dia. DeepReach Fish-tail End-mill, 2-flute, 1.125 in. max DOC, 3.0 in. OAL

Problems

  • 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
