REMEMBER To Reserve Time!

Various tools such as the lasers (Epilog or Audrey), 3D Printers, and Forest CNC need to be reserved before using the tool. Review the Slack channel for the tool to reserve time.

  • All 3D Printers (channel: mfx-3d-printing)
  • Laser Epilog (channel: mfx-laser-epilog)
  • Laser Audrey (channel: mfx-laser-audrey)
  • Forest CNC (channel: mfx-cnc)

Follow these steps to set the home position for your job. Think about how you have defined the job in VCarve Pro and set the home position to match that design.



1. Secure the material

  • Use clamps or whatever method is appropriate for your job
  • You may have to use CNC Controls and manually move the gantry to allow room to secure your material

2. Move Gantry To Job Home - Get Close

  • Use CNC controls to move the gantry to the desired home position
  • To travel quickly to the other end of the table, enable Rabbit mode by clicking the Turtle / Rabbit button until the light is OFF
  • Move gantry to approximate home position

Set Z Position - Step 4

  • DO NOT press SET (F10) at this point. The Z value has been automatically set.
  • If you accidentally press F10 just start over at Set Z Step 1 above
  • Using the CNC Controls, press Z+ to move the bit away from the probe
  • Remove probe and place it safely back on top of the controller

5. Confirm Job Home

  • Press ESCAPE a few times to return to the main menu
  • Select MDI (F3)
  • Enter x0y0z0.25 in the Block and press ENTER to accept the command and then CYCLE START
  • The CNC will move the bit to the job home position with the bit setting at 1/4" above the surface of the material
  • You can use x0y0z0 if you want the bit to touch the material
  • Using the CNC Controls, press Z+ to move the bit away from the material
