Hi, need help. Anyone got GCode settings for a GRBL machine? laser test not working and laser power not functioning i.e. blue light on when running sequence but not burning?

thanks

check here on the last section and make sure you have those and the same value on LW settings, specially $30

Also make sure your PWM range matches your machine configuration. If your machines “rpm range” is 0-1000 and LW setting is 0-100 you might see this as well.

thanks
