Hello! I am trying to tune resonance compensation with an ADXL345 Accelerometer.
I got to the part where you configure your Accelerometer in the printer.cfg file, and after I copy and pasted the printer.cfg code and entered my probe points, I get an error message saying,

"Klipper reports: ERROR

Unknown pin chip name ‘RPI’

Once the underlying issue is corrected, use the “RESTART”
command to reload the config and restart the host software.
Printer is halted

I don’t know what value to put in that line, and I don’t know how to get it. Could someone help?

As stated, Post your log for more detailed help.

But the chip line is the name of the accelerometer you defined in your printer cfg on your toolhead.

[adxl345] is the default but if you gave it a name like [adxl345 toolhead] or [adxl345 gantry] then it will be ‘toolhead’ or ‘gantry’

[adxl345]

cs_pin: RPI:

[resonance_tester]

accel_chip: adxl345

probe_points:

150, 150, 20  # an example

This is what my printer.cfg code looks like. The error line is the “cs_pin: RPI:” line.

Hello! Thanks for your guys’ help. I solved it by entering cs_pin: rpi:None in the code template.
