How to check this:

• Ensure that the USB or Ethernet cable meets the following requirements:

USB cable

• USB 2.0 cable with plug type A to plug type B
• Maximum length of 2 m (approx. 6.5 ft)
• Double shielding
• Ideal for environments with perturbations
• Premium quality

Ethernet network cable

• Performance class: CAT-6
• Screened/Foiled Twisted Pair (S/FTP)
• Maximum length of 55 m (approx. 180 ft)
• Premium quality

Does re-installing the USB or Ethernet cable resolve the issue?

How to check this:

1. Disconnect the USB or Ethernet cable from the machine and the CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC. / USB hub / Ethernet switch.
2. Re-connect the cable to both devices. Ensure the following:
   • The connectors are properly seated in the ports.
   • The cable cannot be inadvertently pulled out e.g. by moving the CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC..
3. Restart the machine and the CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC..
4. Start DentalCNC. Check whether the machine references.

Is the USB or Ethernet cable connected to a hub / switch?

Is the USB or Ethernet cable damaged?

• Check the USB or Ethernet cable for damages such as the following:

• Damaged coating
• Kinks
• Loose or damaged plugs

Is the USB or Ethernet cable wrapped around the suction hose?

Is the CAM computer set up correctly?

How to check this:

• All energy saver settings must be deactivated.
• Machines with a USB port: The setting for selective USB power saving must be deactivated.
• A permanent power source must be available.

Recommendation

1. Exchange the USB or Ethernet cable with cable that meets all requirements.
2. Restart the machine and the CAM computer The computer that is connected to your machine and which runs DentalCAM and DentalCNC..

Recommendation
