Be sure to inform the MIRCX/MYSTIC PI that you are done in the lab and that it is ok to start any alignments or STS recording that is desired. Now the MIRC server is ok to start.

Also make sure that the errors between the laser and target position are small, (0.007µm or less is typical), when tracking at the home switch. If the errors jump when the cart is tracking on the home switch, then turn the cart [OFF], move the cart [BACK] about a meter from the home switch, turn the cart [OFF], and try clicking [TRACK] again. Please wait for each command to register on the OPLE server before clicking the next button in this sequence. If the errors do not stay near zero, the metrology laser may be out of alignment and the signal is low. Pull up a metrology signal window as shown above and confirm the signal is strong. It will look like a sine wave with an amplitude the same as the window height. If it is low, adjust it carefully with the MET2 gui in PICO 2. Get the sine wave to equal the window height. If it is ok and the problem persists, you can try to restart the respective cart’s computer/OPLE1-6 server(s). Try tracking the cart again. After checking to make sure the carts track properly, turn the carts [OFF]</font>. <font 14px/Arial,Helvetica,sans-serif;;#333333;;white>After the carts finish homing, the ople server will say “HOMESETDONE” * To check that the carts have homed properly, click [TRACK] on the Control Tab of the OPLE</font>   GUI<font inherit/inherit;;initial;;inherit>* The cart will track to home switch at the target position of “0.000000” on the OPLE Server * Make sure the “X” lights up and stays steady under the HM column on the Primary OPLE Server for each cart you will be using.

 +The new ople system has a home check procedure that will give the homing error of each cart.  In the ople server, use the command homechk S1, S2,... to have ople check the homing accuracy.  A value of a few microns is usually returned after the cart is checked.  Hit ESC to clear the display and enter the next cart.  If any cart has large values above 20 microns, home the cart again and check the homing until it shows low values.
