Accelerometer problem

General Discussion

Basic Information:

Printer Model: Ender 3 Pro
MCU / Printerboard: Creality 4.2.2
klippy.log
klippy(4).log (6.1 MB)

Fill out above information and in all cases attach your klippy.log file. Pasting your printer.cfg is not needed

Describe your issue:

After ACCELEROMETER_QUERY Klipper shuts down, all the times. This is the first accelerometer, also will connect second for bed after mainboard change.
ADXL345 is connected to RPI 1B+

UPDATE:
After overclocking RPI 1B+ to max value, klipper is working fine (maybe the problem is in callback timeout, sorry I’m not phyton programmer, only an old hardcore C/C++).

A RPi Zero is considered the absolute minimum for Klipper. The B+ is even slower, so it might well be that some things do not work.
Although ACCELEROMETER_QUERY should not be too compute intensive

Thanks for fast answer. I’ll switch to another RPI model.
