Printer Model: Sapphire Pro
MCU / Printerboard: Raspberry Pi 4B, stock Sapphire Pro Mainboard
I am really getting desperate with the setup of inputshaper.
I tried to set it up last week without any luck. Did I miss anything? Thank you for your help!
Hardware: Raspberry Pi 4B with klipperscreen, ADXL345, Sapphire Pro with 2 month old klipper install,
As soon as I add the code from the manual klipper does not start anymore.
Error in the dashboard:
MCU 'rpi' error during config: Unable to open spi device Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software. Error configuring printer
What did I do:
I followed the video from Nero 3D
Guide from klipper Measuring_Resonances + RPi_microcontroller
My ADXL345 looks like the picture on the right and connected it like that, I swapped 100cm cables with 20cm jumper cables as a test.
SPI is active.
systemctl status klipper-mcu is active.
lrwxrwxrwx 1 root root 10 Sep 17 12:13 klipper_host_mcu -> /dev/pts/0
Second ADXL345 sensor tested without luck.
I tried pretty much everything I could find. SD card backed up and copied to new SD card and tested other Pi 4B.
Could klipper screen/drivers cause problems for the GPIO Pins and adxl345?
Is there a problem with my printer.cfg?
Is klipper damaged? I did not install much. Only klipperscreen with driver, obico and mobileraker.
