This is the line of code returning this error : https://github.com/Smoothieware/Smoothieware/blob/edge/src/modules/robot/Robot.cpp#L1271
This error is returned because you sent a command with a feedrate parameter with a value of 0. That’s invalid.
You are sending something that looks like this : G1 X10 F0
F is the feedrate, and a rate of 0 means nothing, thus the error.
So this is not about your configuration, but about the way you are using your host program.
