have you enabled the pi i2c bus? https://www.klipper3d.org/RPi_microcontroller.html#optional-enabling-i2c

which fits with an mpu9250 showing its first i2c address
rancid nymph
its an mpu6050
remote marten
where was it sourced from?
rancid nymph
amazon
remote marten
i think it should have same i2c addresses anyway. do you have a link to the product page?
remote marten
it's possible the pullups on the board are specced badly - even though the device shows up communication may be failing
although if the picture is to be believed they're shown as 2k2
i do note that the product page shows it as a gy-521 which i would need to research compatibility for
remote marten
because it can't talk to the sensor you've configured
klipper won't start until it can communicate with all the peripherals
rancid nymph
the syntax highlighting seems wrong
remote marten
just to check, where have you added that?
rancid nymph
printer.cfg
remote marten
cool. agree the syntax highlighting does look a little odd as if you were in a log/conf file
rancid nymph
i have a feeling something hre might not be correct
remote marten
you can try adding the line i2c_address: 104 below the i2c_bus line
rancid nymph
why 104? it was 68, no?
remote marten
which equates to the hex address we saw on i2cdetect (although it should be the default)
0x68 hex = 104 decimal.
i2c addresses are weird.
rancid nymph
printer is still not ready
remote marten
got a picture of your wiring? i'm running out of ideas besides "try another accelerometer"
rancid nymph
like the actual wiring or the diagram?
remote marten
your actual wiring
there can't be much wrong with it though as it's showing up on i2cdetect
i've had so many issues over the years buying cheap breakouts on amazon/ebay/aliexpress though, they usually just cause frustration

can you see the numbers on the two resistors next to the SCL label?
