Open the XRD Commander program using the icon on the toolbar. Figure 23 is the initial window. Be sure you are in the Adjust tab (btm left, 23A23C).

First initialize the Sample Changer. The checkmarks (Figure 23B) indicate the drives that will be initialized. Check all boxes with values before initializing, click on Init SC (Figure 23A). The program then 'locates' all the mechanical drives in the D4. It typically remembers the Theta, 2Theta, and Phi drives but the Divergent Slit sometimes does not initialize. That should not be an issue for scanning samples as our Div. Slit is not mechanical, however if the software won't scan a sample because one or more of the drives did not initialize (successfully initialized drives will turn blue) you can try restarting the program and reinitializing, and/or turning off the D4 and the commander software and restarting the instrument then the commander software and following repeating the steps above. If that does not work, close XRD Commander and open D4 Tools from the desktop. Note D4 Tools and XRD Commander cannot be open at the same time.
D4 Tools allows you to see what is causing an error in the D4 instrument . Click and remediate it. In D4 Tools, click the icon on the left (Figure ##A), this connects the D4 Tools software with the D4 instrument and completes a diagnostics (identifies any errors). The initial screen (Figure ##) shows the instrument status. Any red squares indicates an error. You can investigate the error by clicking on the square. Only trained techs should be trouble shooting errors (errors other than drive initialization) on the D4. To initialize the drive(s) that did not initialize with the commander software click the '+' positioning drives, then click the drive that did not initialize (Figure ####B). Click the Adjust button (Figure ##A). Please note that when you initialize the drives you can hear the drives moving inside the D4. If you hear a clank or bang and the instrument stops working you will have to get a trained tech (trained in D4 trouble shooting). There is a in-depth sample changer procedure to correct for misalignment in the Bruker Manual (cupboard in XRD lab) but it should only be preformed by trained techs. Alternatively, you can contact Bruker and they can advise or remote into the D4 to fix any errors.Go to the drives that will not initialize and click the "Adjust" button. Then close D4 Tools and reopen XRD Commander. The "Adjust" command can also initialize the drives. The diffractometer's sample-changer drives will adjust inside the instrument. If you hear a crash or the program gives an error, see the procedure for readjusting the sample handler in the Bruker manual. This is a lengthy process. Note that some errors can be fixed by clicking the Red Cross icon (Figure ##C). The program can identify and fix some errors. Try that icon before contacting Bruker.
