i2c error in mattercontrol after build Rostock v3 wont let me G29

Post by sanderbing » Sat May 04, 2019 6:48 pm

After what i thought was a successful build, i did all the firmware and went to calibration but when sending G29 code thru matter control, i got the following error

<-accelerometer send i2c failed.
<-accelerometer i2c recv failed.
<-I2C Error - Calibration Aborted
<-Error:Wrong checksum

my temps are good, display is normal, except the error message.

Does anyone know what is causing this and how to fix? thank you

Make sure the terminal connector at the HE280 is fully seated. Also, don't use G29 - use the "full calibration" feature in the menu via the front panel.
