I designed some mounts for kusba adxl345 usb pcb by maker panda for my Elegoo Neptune 3 Pro. For klipper resonance compensation/measuring: https://www.klipper3d.org/Measuring_Resonances.htmlLink to a good (german) documentation:https://book.cryd.de/books/klipper/page/youtube-adxl345-einrichtenLink to the kusba adxl345 usb PCB at AliExpress:https://de.aliexpress.com/item/1005005182131890.htmlYou will need:1x or 2x kusba adxl345 usb pcbs (when you use 2, you don't need to switch the pcb/mounts)1x M3 12mm Screw, Nut (& Washer optional)2x M3 6mm Screw, Nut (& Washer optional)2x M3 10mm Scew & Nut2x M3 8mm Screw, Nut (& Washer optional)See Pictures for Details.I also added the FreeCad Files (i used Version 0.21.1) if you need any customizations.In case you use 2 adxl345 chips, here is my printer.cfg snippet:[mcu adxl_hotend] # Hotend (X Axis) # find your correct device id's with "ls /dev/serial/by-id/*" on your RasPi serial: /dev/serial/by-id/usb-Klipper_rp2040_E6624C9027674638-if00 [mcu adxl_bed] # Printbed (Y Axis) # find your correct device id's with "ls /dev/serial/by-id/*" on your RasPi serial: /dev/serial/by-id/usb-Klipper_rp2040_E6624C9027418D2F-if00 [adxl345 hotend] cs_pin: adxl_hotend:gpio1 spi_software_sclk_pin: adxl_hotend:gpio2 spi_software_mosi_pin: adxl_hotend:gpio3 spi_software_miso_pin: adxl_hotend:gpio0 [adxl345 bed] cs_pin: adxl_bed:gpio1 spi_software_sclk_pin: adxl_bed:gpio2 spi_software_mosi_pin: adxl_bed:gpio3 spi_software_miso_pin: adxl_bed:gpio0 [resonance_tester] accel_chip_x: adxl345 hotend accel_chip_y: adxl345 bed probe_points: 120,120,20After restart, you should have 2 new MCUs ("mcu adxl_bed" and "mcu adxl_hotend") in the "MACHINE" menu.You now can use the following Console Commands:TEST_RESONANCES chips="hotend, bed" axis=XandTEST_RESONANCES chips="hotend, bed" axis=Yto measure resonances on the two axis.
