 Sometimes when observing, the dome will not follow the telescope during a slew. This can happen when the Autodome feature is not turned on. Click the ON button on the MAIN tab of the telescope gui to enable it. This may happen after a server restart so always check the dome position with the spycam during a slew after a server restart. Also make sure the target position of the dome matches the telescope's position. If not, it will insist on being in the wrong place. If it is not at the same AZ as the scope, manually move it until it is centered on the telescope in spycam 1. If the dome AZ does not read the same as the telescope AZ, enter the scope AZ in the position box of the DOME tab of appropriate dome server and hit the INIT POS button to tell it at what AZ it is. \\  \\ Sometimes when observing, the dome will not follow the telescope during a slew.

-If the dome does not turn at all, even with the manual controls on the telescope or dome guis, the control may be set to manual on the control box. This can happen if there was work done at the dome during the day. If the dome opens, but does not turn, check to see that control of the dome rotation is in the computer position and not manual on the dome rotation controller box just inside the door of the bunker. Sometimes the drive wheel jumps in the track and cannot turn the dome, even when the motor works.  This will need to be fixed during the day.+If the dome does not turn at all, even with the manual controls on the telescope or dome guis, the control may be set to manual on the control box.

   * Good metrology signals are important to the proper positioning of the carts. Monitor the signal strength by running [RUN MULTIPLE] on the Metrology Monitor. Place the windows above the TV windows for each scope you are using. They should show white sine waves that are around the height of the window. Erratic, fluctuating waves indicate self-interference or a weak signal. This may cause the carts to lose their place as the signal strength falls too low. Red waves indicate that some displayed signal has gone too low and the carts will all need to be homed. A careful adjustment of the MET2 mirror can sometimes bring the signal back. Do not adjust the MET1 mirror.   * Good metrology signals are important to the proper positioning of the carts. Monitor the signal strength by running [RUN MULTIPLE] on the Metrology Monitor.

-  * To home the carts, turn off the [OL] and [MAN] buttons on each cart and it will automatically return to the front switch. If the cart has no issue, it will arrive at the target position of 0m and the home switch at the same time. The X in the OPLE server under the HM will indicate it has stopped on the home switch. If a cart does not reach the home switch when it returns to position 0m, it was lost and likely the cause of the difficulty in finding fringes.  The X does not guarantee the cart has retained its home position.  This can only be done by using the CHECK button on the ople gui or by typing the command "homechk S1" into the ople server.  When the error value is displayed on the ople server, hit ESC to clear the display. Click on the [OL] and [MAN] buttons and hit [TRACK] to send the cart to the desired cart position.+  * To home the carts, turn off the [OL] and [MAN] buttons on each cart and it will automatically return to the front switch.
