- Ensure that the switches circled in white in the image to the right are in the off position, then turn on the killswitch (Circled in red), and turn on the dedicated desktop computer. Mach3 is available under MS Windows.
- Turn on all three lightswitches: back of the "MicroProto Systems, MicroMill DSLS 3000" box, top of the M3/M5 box, and to the side of the mill spindle.
- Double click the desktop shortcut "CNC_mill" to open software. "Tab" key brings up the jog controls.
- You may have to hit reset button before the manual controls will work
- MDI tab in Mach3 allows manual G-Code entry. This is useful for commanding the mill to specific locations (eg. g0 x0 y0 z5) .
- Gently change mill bits with crescent wrenches. Finger tight is often sufficient.
If, for some reason, you need to turn off the CNC mill while it's milling, please use the killswitch. It was added to eliminate the need to stick one's hand in hazardous places.
- Turn off all three power switches noted above.
- Shutdown dedicated computer.
- Please cleanup the mill area and place tooling back into the mill toolbox under the bench.
 Please Avoid
- Obviously, don't put your hands in hazardous places.
- Stay with the mill unless you really know what _all_ the risks are. Strange things can happen, particularly "dig-in" and g-code misinterpretation.
- Milling the mill itself (or our mounting hardware) is easily possible, and a rather expensive mistake.
- Use G91.1 with certain automatically generated G-Code files (eg. pcb2gcode, solidcam). Mach3 seems to default to absolute arc/circle center coordinates which catastrophically enlarges the arcs/circles.
Otherwise, the mill is robust and newbie friendly.
