In my dayjob as an implantable-device engineer, I often need to prototype small parts. So, after the successful modification of my home X2 mini mill to CNC, I decided to do the same to the Sherline precision micro mill that I have at work.
I used three steppers and couplings sold by Sherline for their baby mills:
The steppers are controlled from a box that is very similar to the one I described in my post about the CNC mod of the Sieg X2 mini mill. The steppers are driven by three CW250/2/8 stepper controller modules. Power for the CNC system is derived from a HF-240W-5F-30 240W 30V/8.0A power supply.
Lastly, I added to the cart a dedicated Pentium 4 computer with Windows XP to run ArtSoft‘s Mach3 CNC software:
The conversion works perfectly! I love Mach3!
