- Check beam on the exit slit camera (cam6) on the m3r_align panel. If there is no beam and piezo voltage is very high (-12V or 40V), try set it back to zero.

- This happens when the code had hard time to determine where the peak is. Try tweaking the piezo voltage back to zero and adjust m3r pitch.

|
|
|
- When the photon energy is too high (> 2.3 keV), or the mono and ID energies are very different, photon counts can be too low to determine the peak position. Try increasing gain and exposure time (`t(s)` on the screen) of the camera.

|
|
|
- Change mode on the ID screen (29ID main screen -> ID -> IEX Machine Physics), wait until it's done, and change the mode back. This will reset the ID.

4. Motor gets stuck.
|
|
|
|
- Turn on the light in Kappa chamber and check if there is any collision or cable winding.
|
|
|
|
- th and chi motors tend to get sticky after scanning around a peak for many times. Try tweaking the motor back and forth manually.
|
|
|
|
- Contact beamline staff if moving back and forth doesn't help.
|

|
|
|
|
|
|
5. Motor positions are incorrect.
|
|
|
|
- Turn on the light in Kappa chamber and check motor positions.
|
|
|
|
- If positions do not reflect physical positions. This is usually due to ioc crash/reboot. Contact beamline staff.
