-<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,</font>  use the [CHECK] button on the ople gui to have ople check the homing accuracy. A value of a few microns is usually returned after the cart is checked. If any cart has large values above 20 microns, home the cart again and check the homing until it shows low values.<font 14px/Arial,Helvetica,sans-serif;;#333333;;white>Once all carts have displayed low errors for the CHECK procedure, click [TRACK] on the Control Tab of the OPLE</font>   GUI<font inherit/inherit;;initial;;inherit>to track the cart to the 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. Also make sure that the errors between the laser and target position are small, (0.007-0.020µm 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, send the carts back to 20m or so and turn them off.</font>+<font 14px/Arial,Helvetica,sans-serif;;#333333;;white>After the carts finish homing, the ople server will say “HOMESETDONE”.

 If using the CHAPMtoMet feature, once the OPLE server has fully started, please check sockman for CHAMPtoMet. If it is running, then MIRC is ok to start. If it is not running, log into the ople computer and run the command : CHAMPtoMet This is case sensitive. This is not the usual mode of controlling the carts. If using the CHAPMtoMet feature, once the OPLE server has fully started, please check sockman for CHAMPtoMet.
