## troubleshooting
## Troubleshooting
1. There is no beam.
- Make sure there is beam in the storage ring.
- Check if main shutter and branch shutter are open. If any shutter cannot be openned, Check beamline EPS and call stuff.
- Check if main shutter and branch shutter are open. If any shutter cannot be openned, Check beamline EPS and call staff.
- Check if ID and mono energy setpoints are consistent.
- Check beam on the exit slit camera from m3r_align panel.
- If there is no beam and piezo voltage is very high (-12V or 40V), try tweaking it back to zero.
- Check beam on the exit slit camera 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.
2. `m3r_align` doesn't work.
- This happens when the code had hard time to determine where the peak was. Try tweak 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 exposure time (`t(s)` on the screen) of the camera.

3. ID gets stuck.
- Change mode on the ID screen (`IEXMachinePhysics.adl`), wait until it's done, and change the mode back. This will reset the ID.
