- Turn on dedicated desktop computer, start Mach3.
- 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.
- "Tab" key brings up the jog controls.
- 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.
- 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.
- Mach3 will not correctly handle circles in metric units. If G21 and G3 (possibly G2 as well) are used in the same gcode program, disaster will result.
- Milling the mill itself (or our mounting hardware) is easily possible, and a rather expensive mistake.
Otherwise, the mill is robust and newbie friendly.
