Is there a way to debug accelerometer connection issues?

What kind of issue do i have?

1.5.2021, 15:42:23: M955 P0 C"spi.cs2+spi.cs3": Accelerometer 0:0 with orientation 20 samples at 1344Hz with 10-bit resolution

M956 P124.0 S10 A0

1.5.2021, 15:45:43: M98 P"0:/macros/ACC": Error: Response timeout: CAN addr 124, req type 4014, RID=0

@clownsrache after sending that M955 command, what does M955 without parameters respond with?

RRF 3.3RC1 with configurable accelerometer SPI frequency is now available at https://github.com/Duet3D/RepRapFirmware/releases/tag/3.3RC1.

@diamondback how would u use a USB cable? it only has 4 wires but we need 7 for the adafruit accelerometer

@tekstyle I have had good results with ribbon cable, ensuring that the CS wire is not next to any other signal wires. See the images and description at https://duet3d.dozuki.com/Wiki/Accelerometers#Section_Direct_SPI_connection_to_a_Duet_main_board.

Use an USB 3 cable It has 8 wires.
