User Interface Software

UGS and FluidNC Web Installer

What happened?

I got a report from a user where UGS failed to connect to a controller due to an invalid YAML configuration: winder/Universal-G-Code-Sender#2573

The proper way to include a colon (or other "special characters") in a YAML configuration value is to wrap the whole string with either " or '. The problem is that UGS uses the $Config/Dump which only prints the value without the string-wrap:

$Config/dump

name: CNC Router XYYZA 0-10V spindle and laser
