[SOLVED] Help connecting an accelerometer

zapta

I am trying to connect a LIS3DH accelerometer to a Mini5+ printer.

Firmware version is

Wiring diagram is

When I type the command per the instructions I get

Before I start debugging the wiring and try to look at signals, is this the right process to set it up? Should I had additional accelerometer related configurations (currently I have nothing in config.g). And if it should work, any suggest what to check next?

Ok, I connected a 330 ohms resistor in series to the SDO output and the M955 command completes without errors. Next I will try to actually use the accelerometer but it seems that the immediate problem is solved.

Have you placed the resistor right after the board connector or the accelerometer connector?
Thanks

@thedragonlord , I connected the resistor on the accelerometer side.

I also tried 7 ~1.5m loose wires and it worked well without the resistor.
