| Physical defect on device (bent pin) creates glint Window(s) of LNC60 not clean Wrong tip size installed Offset for tip measurement incorrect Component rotation may not have completed during inspection "Wobble" during probe rotation Device slipping on tip Head-leveling procedure and shims not applied
| Try another device Clean windows while observing P1 and P2 laser images in gantry screen or on VB diagnostic tool Verify tip is installed correctly/completely Place a device on tip. Use servos screen or MMI to perform a back-and-forth rotation. Rule-out device slippage, lop-sided probe rotation, rough rotation Perform head-leveling procedure

Component rotation may not have completed during inspection. It may be necessary to check encoder response to head rotation for correct resolution and direction. Verify component parameters and shape are adequate. (no-results-available) | | |

Encoder Check ProcedureThe overall goal is, to spin the heads 360 degrees via the Motion Manager, and verify 5000 (or very close to 5000) counts are seen.
By the CyberOptics sensor via the LNC60 VB6 Sample App. I would set a dwell ~5 seconds after each back-and-forth move in Motion Manager so you can see the results before the next movement.
The probe 1 setup is nearly the same as 2
In the LNC60 VB6 Sample App, select Detector 0 and Open Sensor
Update the Head Setup: Head 1 parameters as below and click-on Set Setup
Click Reset Encoders
Click Get Positions. In the Status Display window, 0 revolutions should be indicated.
Start the motion manager (back-and-forth motion)
Click on Get Positions after each movement. You should see similar info in screen two below.
