FLSUN SR - ADXL345 SUPPORT

This is a probe made for use of the USB trianglelab ADXL345 acelerometer on FLSUN SR printers. The probe was sized to attach using zip ties to the support for the leveling probe.

The accelerometer I used has a pre-soldered USB-C interface (or even pins) and is shipped with all the necessary wiring.

Three variants were made:

- Horizontal: The sensor is arranged horizontally allowing for greater stability and more integral with the printhead. However, it is bulkier in that to allow room for the arms to move, it had to be raised more than the other 2 variants

- Vertical: The sensor is arranged vertically allowing for a smaller encumbrance at the expense of some stability of the stand that will be more prone to bending during rapid movements

- Slim: The sensor is arranged vertically and the stand has been stripped of all excess material. This adds less inertial mass to the printhead, but at the same time is the least rigid and weakest variant of the stand 

Four TCEI M2x6 screws were used to attach the accelerometer to the probe. The holes are not threaded and are intentionally narrow so that the screws can grip the holder well. Some force may need to be used for initial installation.
