#### CMM Startup and Homing Procedure

Using online PC-DMIS, you can execute existing part programs, quickly inspect parts (or sections of parts), and develop part programs directly on the CMM. Online PC-DMIS will not function unless it is connected to a CMM. Offline programming techniques will work while online.

CMM Startup and Homing Procedure for PC-DMIS Online:

1. Turn on the air to the CMM.

2. Power on the controller.

- Depending on the machine model, this may be a large rotary switch, an on/off key, or a small rocker switch on the controller mounted on the back of the machine or workstation.

- All of the LEDs on the hand control (jog box) will be illuminated for about 45 seconds. After that time, several LEDs will turn off.

3. Power on your computer and all of its peripherals, and then log on to your computer.

4. Start PC-DMIS online by double-clicking with the left mouse button on the Online icon in PC-DMIS's Program Group.

5. Home the CMM. Once PC-DMIS opens, a message will appear on the screen:

PC-DMIS Message

Do a machine start (if needed), then press OK to home

OK | Cancel

- Press the Mach Start button on your jog box for several seconds. Its LED will illuminate.

- The CMM needs to be "homed" to properly set the machine zero and enable the machine parameters (speeds, size limits, etc.). Press the OK button from the PC-DMIS message mentioned above. The CMM will slowly travel to the home position and establish this position as zero for all the axes.

6. Use PC-DMIS to program and execute your part measurement routines. See the "A Simple Tutorial" section if you are new to PC-DMIS.

Changing Machine Parameters

Numerous machine parameters can be set to control the speed and motion of the machine. See the "Setting Your Preferences" section in the PC-DMIS Core documentation if you ever need to change your machine's parameters.
