Bigtreetech Pad 7 - adxl345 Sensor Problem in Klipper


Recommended Posts

I am using the Pad 7 and i want to set up Input shaping.

But i can't get the printer.cfg to work with the settings needed.

I always recieve an MCU 'rpi' error during config: Unable to open spi device when trying to boot up my printer.cfg

i have added these parameters in my config:


[mcu rpi]

serial: /tmp/klipper_host_mcu



cs_pin: rpi:None

spi_speed: 2000000

# spi_bus: spidev2.0

spi_bus: spidev1.1



accel_chip: adxl345

accel_per_hz: 70




I set my pad up as shown here in Aurora Tech channel with a printerconfig for my printer on github https://www.youtube.com/watch?v=8vkzpvia4mg&ab_channel=AuroraTech


Thanks for your help!
