Operating Instructions

Preparation

  1. Build your part model using CAD software
  2. Pick tooling and material then calculate feed and speed (do not skip this step)
    • Speed & Feed Table - Look up tool FPT and material SFM. There are also some good depth of cut recommendations near the bottom of this page. If machine rigidity is an issue cut shallower, not slower.
    • Milling Speed and Feed Calculator - Input FPT and SFM to determine spindle speed (RPM) and feed rate (IPM). Keep in mind that the spindle speed must be between 8,000 and 24,000 RPMs on this machine.
  3. Generate GCode

Startup

  1. Clean the machine
    • Wipe down all linear guide rails
    • Remove dust and debris from the work table
  2. Power up the system
    • All power is run off of a single power strip that is located under the main work table
  3. Check cooling fans on all 4 drive motors
  4. Check cooling fan on stepper controller under work table
    • This fan needs to be pointed at the bottom of the stepper controller, otherwise it will get very hot and could potentially cause damage.

Operation

For general operation, see Section 3.1 "General Work Flow"

  1. Load GCode Section Section 3.1.2, Page 45-48
  2. Make sure the Big Red Button(tm) on the right side of the machine is pulled out
  3. Enable the machine by hitting the green "Mach3 Reset" button on the "Load" page Section 2.2.3.2, Page 39-40
  4. Find machine zero Section 3.1.2.9 Page 49-50
  5. Set the work coordinate offsets Section 3.1.3, Page 54-58
  6. Set the spindle speed (on front of router) and turn on the router (on right side of router)
  7. Say a brief prayer and put one hand near an E-Stop
    • The red button on the XBox remote
    • The Big Red Button(tm) on the right side of the machine
    • The "Mach3 Reset" button on the touch screen Section 2.2.3.2, Page 39-40
  8. Run the job by hitting the green "Cycle Start" button [Section 3.1.6, Page 63
  9. Stand back
  10. Start cleaning up dust, seriously... please clean up after yourself.

Shutdown

  1. Turn off router
  2. Clean the machine, for real this time
  3. Exit Mach3 (or the next step will fail)
  4. Shutdown the computer (Start, Shutdown, OK)
  5. Turn off of the power strip
  6. Post pictures of the awesome thing you just built
