# Known issues In general BakingTray is very stable and almost all acquisitions complete without errors. The full list of issue can be found on the [BakingTray issue tracker](https://github.com/SWC-Advanced-Microscopy/BakingTray/issues). The more notable issues are as follows: * During acquisition with linear scanners [Issue #20](https://github.com/SWC-Advanced-Microscopy/BakingTray/issues/20) or a high level of averaging with resonant scanners [Issue #234](https://github.com/SWC-Advanced-Microscopy/BakingTray/issues/234) there are multiple instances of duplicate tiles appearing in the preview window. This does not affect the saved data. * We use an [NI USB-6343](http://www.ni.com/en-gb/support/model.usb-6343.html) to control the PMT gains. This works but we see the following bug: there is a rare chance that, when BakingTray is open, [switching off the PMTs causes MATLAB to crash](https://github.com/SainsburyWellcomeCentre/BakingTray/issues/13). We work around this by disabling PMT auto-on and having BakingTray issue the PMT off command at the conclusion of acquisition only. We experience no problems or acquisition failures when working like this. ## Hardware-related issues. * PROBLEM: Coherent lasers rarely switch off or close the shutter during the first section. This has never happened later in the acquisition. SOLUTION: Deleting the files in the acquisition directory and re-starting the acquisition. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
