# Remote Diagnostic: X and Y Skip Test The purpose of this test is to **diagnose your printer's X-axis and Y-axis movement.** This test will run the gantry system along the x-axis or y-axis to ensure it moves from end to end without skipping. Please upgrade to the latest software package, to run the following X and Y Skip diagnostic tests. Software Version 2015-03-24-9.4 is used as an example in this article. 1. Please **go to Expert mode** on the Advanced page in the Settings menu. ![](https://s3.amazonaws.com/cdn.freshdesk.com/data/helpdesk/attachments/production/5016983768/original/ExpertMode.JPG?1431442561) 2. After selecting the Expert Mode checkbox, the M3D Print Spooler window will open. \ Please **select the Diagnostics tab** that is located on the top of the printer options. ![](https://s3.amazonaws.com/cdn.freshdesk.com/data/helpdesk/attachments/production/5016984730/original/DiagnosticsTab.JPG?1431442786) 3. After selecting the Diagnostics tab, you have the option to perform a number of tests to diagnose X-axis and Y-axis movements. 1. The Skip tests will step every 1 second along the X or Y axis, depending on which button you click. 2. The Speed tests will quickly move the print head along the X or Y axis. 3. During the skip tests, please watch and listen closely to see if the printer skips. You will see and possibly hear a slight stall/skip while the print head travels during the test. 4. If you determine the printer skips in one or both directions, use the [X-Axis Services](https://printm3d.com/solutions/article.php?id=39) and [Y-Axis Services](https://printm3d.com/solutions/article.php?id=38) support pages to find a solution. Also, you can report your findings to our tech support team.\ ![](https://printm3d.com/solutions/assets/img_557f039298304.png) We hope these instructions prove useful.
