This article is relelvant to all versions of DentalCAM and all vhf milling machines


vhf milling machines should always maintain a connection to the milling PC (i.e. the PC where DentalCAM is installed)


Please ensure that the PC does not go into "Sleep" or "Hibernate" modes during a job's milling.


One common setting that can effect milling is the USB Selective Suspend Setting.  We recommend that you disable this to avoid any PC > Milling machine disconnects.


  1.  Go to Control Panel > Power Options
  2.  Click on “Change when the computer sleeps”
  3.  Pull down the “Put the computer to sleep” option and set this to “Never”
  4.  Click on “Change advanced power settings”
  5. Scroll down to “USB Settings” and press +
  6. Press + on “USB selective suspend setting” and set this to “Disabled”
