 +===== How to export configuration? =====
 +- Get a micro SD card, up to 32G will be enough.\\
 +- (Optional) Format it to filesystem FAT32 ([[https://www.lifewire.com/format-sd-card-to-fat32-6666166|howto]]).\\
 +- Insert in the Display contacts on top.\\
 +- Go to "Controller > Settings and Update".\\
 +- Select "Export config." and a .cfg file will be created on the SD card.\\
 +- Copy this file from the SD card to the computer and send file to support.

-Check the performance of the hall sensors in the **Controller** > **Debug information** > **Hall input** section, this parameter has three digits, each shows the signal level, if you rotate the motor slowly by hand, then all three digits should change. If none of them changes, check if the hall connector is connected or the ground may be broken. If one of the numbers does not change, there is no contact or the sensor wire is broken. To check the contacts in the controller, you need to disconnect the hall connector and measure the voltage at the controller connector. There should be about 4V on the signal lines of the halls, 5V on the power supply and about 3V on the temperature sensor line.+Check the performance of the hall sensors in the **Controller** > **Debug information** > **Hall input** section, this parameter has three digits, each shows the signal level, if you rotate the motor slowly by hand, then all three digits should change.

 +===== Motor shakes at start =====
 +Go to **Controller** > **Motor setup** > **Position sensors** > **Hall settings**, scroll down to sensors **Offset** values, if your average offset more than 10 degrees that may produce shaking at start. In case with mid-drive motors (like Surron) you can rotate your sensor plate by a tiny bit to adjust sensor position, run **Motor setup** and **Angle correction** after each adjustment to calibrate sensors until they are placed at better offset angle.

- +Note: Log rates faster than 10ms (e.g., 1ms and less) may result in gaps in logger data due to the limits of the CAN bus speed. You can select 'Mode = Max rate' to attempt recording at the maximum possible data rate.
