adxl345 crashing the MCU

I have been trying to follow the RATOS wiring for the octopus max ez to wire in a adxl345. The printer works fine without the adxl but the MCU will not boot with it attached. what do i need to do the wire the ADXL into the RPi ? I have run into issue with trying to get the SPI bus to work for other things so if i can avoid it that works better
Solution:
https://www.klipper3d.org/Measuring_Resonances.html If you want to use the pi you should be able to follow the usual klipper guide for wiring and then add in your user overrides section ``` [include RatOS/boards/rpi/config.cfg] [include RatOS/boards/rpi/rpi-adxl345.cfg]...

how did you wire the ADXL?

So i have 6 wires soldered into the spots inidcated on the RATOS page for the ez max, those run to plugs and attach to the ez max pins in the same diagram. I tried both the 3.3v and 5v pins and neither seem to work

that worked great! the only thing I ended up doing slightly differently is I was having a hard time getting the RPI adxl345 file in the right location so i just added the text to the override section and it all worked. I also switched over to some old cat6 cable for the wiring.
