Error: G29: No valid grid defined for bed probing

[DatTurtle]

I recently got a BLTouch set up and have been trying to probe my bed but keep getting the same error with g29/g29 s0. Probe deploys/retracts fine and g30 works for single probes but I'm missing something with my grid. Thanks for the help!

Your M557 grid command says the range goes to X390, but your M208 says the X axis is only 380mm long.

You're also missing the XY offset of the probe in your G31 command.
