### Basic Information: Printer Model:ender 3v2 MCU / Printerboard:skr mini e3 v2 Host / SBC klippy.log _Fill out above information and_ _ **in all cases attach your** _ **`klippy.log` _file_** (use zip to compress it, if too big). _Pasting your_ `printer.cfg` _is **not** needed_ _ **Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there** _ ### Describe your issue: …Hi people im really hoping for some help. i have wired my adxl345 to my rpi 3b via spi connection i have enabled spi added the rpi mcu and when i have the adxl345 in my printer.cfg my printer wont connect to rpi but soon as i delete the adxl345 config printer works. i am using the 32bit mainsail image as on my rpi 3b the 64 bit kept freezing.. this is what i added to config [mcu rpi] serial: /tmp/klipper\_host\_mcu [adxl345] spi\_bus: spidev0.0 # Explicitly define the Chip Select pin as GPIO 8 on the RPi cs\_pin: rpi:gpio8, and i was told to delete that config and try this: [mcu rpi] serial: /tmp/klipper\_host\_mcu [adxl345] spi\_bus: spidev0.0, but still no luck. also is a klipper.log attached. Hope some can help. Thank you [klippy.log](https://klipper.discourse.group/uploads/short-url/l6DAw615fS4Crk2DMI9m72krWfp.log) (2.4 MB) ---

This is most likely a cable/connection issue. What kind of cable are you using for the accelerometer and how long is it? ---

Hi again, well I got the usb fly ADXL345 and got it all setup and managed to run a test and all worked. The next day after I had gone over the Printer making sure all screws bolts and that were secure. So now the ADXL345 wont connect I get the blue box with waiting for connection and then the red box with the no MCU I’ve noticed that soon as I put # infront of the ADXL345 settings in my Printer. cfg and do firmware restart I t connect. Please can you help with this Thsnks ---

Probably a USB address issue. Did you use the same USB port? Even so Linux can be fickle with USB identification. ---
