ECHO outputs serial data with "echo:" attached in front of it. This allows you to send data to replicatorg witout causing error messages. Debugging level needs to be set to "INFO" in repg.
Using the streaming lib, messages can be sent like this:
ECHO ("Maximum feedrate "<<_FLOAT(max_feedrate,2))
will output "echo: Maximum feedrate 300.00"
ECHOLN(x) is the same as ECHO, but adds a linebreak after.- Loading branch information
