  2. MC XL Installation Requirements • Same power requirements as CEREC 3 Milling Unit • Table must support 100 lbs • To upgrade existing Customers, Acquisition unit needs Wireless LAN Card Kit • Acquisition Unit PC min. must be “E” or higher • For inLab, PC be “E” series equivalent and must have existing network card. All existing Patterson PC’s are compatible.

  3. Engineering Features • Larger water tank, more mills before refills, switched timer interval, can’t run unit w/o filter, check valves prevents drips • Direct Drive motors, no gearboxes • Sealed chuck buttons • Roller bearings on shafts • Replaceable burr chucks, even with flush broken burrs • inLab has shaft bellows for high YZ usage • inLab has 4 motors, 2 burr sets, if a burr breaks on 1 set, unit continues on other set or load full contour and inlab burrs, sw will automatically pick correct burr set for restoration type. • User message display panel. No need to read message at Acq unit or PC. • Calibration Data stored on Milling unit, not Acq/PC • Automatic Downloads, no manual reset • Visual indication of XL status via of colored lights in chamber. • Wlan /Lan communication interface means more freedom to add units.

  4. MC XL Setup 1. Water Tank • Water must be filled to the brim (A) • Tank capacity= 4 liters. Dentatec dose= 100ml

  10. MC XL Setup 7. Rear Wireless Network Connection • Turn off MC XL • For WLAN (A), install jumper (typical installation)

  11. MC XL Setup 8. Rear Network Connection (cont.) • For LAN direct cable connection, install cable in port marked “LAN” (B)

  12. MC XL Setup 9. Acquisition Unit Direct Connection • Connect other end of network cable to lower port (A) on rear of Acquisition Unit

  13. MC XL Setup 10. Install WLAN Card Kit in Acquisition Units w/o WLAN • Use enclosed instructions to disable Windows Firewall, install card and load/configure software

  14. MC XL Setup 10. TCP/IP Overview • MC XL units use network connectivity for communication. • MC XL TCP/IP = 192.168.230.1XX • ACQ or PC TCP/IP = 192.168.230.2XX

  15. MC XL Setup 10. TCP/IP Overview • ACQ or PC TCP/IP = 192.168.230.2XX • For multiple WLAN ACQ’s, TCP/IP address need to be unique. Last 3 digits must be changed on each ACQ unit.

  16. MC XL Setup 10. TCP/IP Overview • To set up unique WLAN TCP/IP Address • Open Windows Control panel • Open Network Connections

  17. MC XL Setup 10. TCP/IP Overview • To set up unique WLAN TCP/IP Address (cont.) • 3. Right click on Wireless Network Connection • 4. Click on Properties 3 4

  18. MC XL Setup 10. TCP/IP Overview • To set up unique WLAN TCP/IP Address (cont.) • 5. Select Internet Protocol and click on Properties.

  19. MC XL Setup 10. TCP/IP Overview • To set up unique WLAN TCP/IP Address (cont.) • 6. Change last 3 digits to a unique number between 201 and 254. • Then click OK • and reboot.

  20. MC XL Setup 11. Load CEREC 3D V3.XX Software on Acq /PC • CEREC/inLab 3D V3.XX software required to operate MCXL units

  21. MC XL Setup 12. Add Device in CEREC 3D Software • Turn on MC XL. * For WLAN units, turn on and configure one at a time, leave others off. • Bootup Acquisition Unit • Open CEREC 3D software

  22. MC XL Setup 13. Add Device in CEREC 3D Software (cont.) • Click Yes to prompt for setting up milling unit • Label Milling Unit and click “Add” You are ready to mill!

  23. MC XL Maintenance • Burr change • New chuck design with new tool • 2 turns to loosen • Tighten burr until click • Milling Unit Calibration • New calibration specimen and pins • Simular menu • Inlab requires both burr sets to be calibrated

  24. MC XL Maintenance, Burrs • New burs: cylinder pointed bur 12.0 mm step bur12.0 mm for chairside materials and inceram cylinder pointed bur 20.0 mm step bur 20.0 mm for oxide ceramics such as YZ, inCORIS

  25. MC XL Maintenance • Water change • New tank, double capacity • Requires 100ml of Dentatec • Approx 120min’s of milling before change message • Filter change interval TBD, maybe 100 milled units • Tank sensor

  26. Adding Multiple XL Milling Units (Demo) • Max. 2 units per Acquisition Unit or PC. • Setup example • Connect WLAN Jumper on MC XL • Open CEREC 3D SW • Click on Settings>Configuration>Devices>Add Device Automatically and label. • Ready to Mill
