Conflicting Configurations
-
I am struggling trying to get my Co2 laser to respond to PWM commands. Unfortunately the documentation is conflicting so I am unsure which is correct or if I am doing something wrong.
I have a Duet 3 mini 5+ and a 50W PSU for the laser.
Per the documentation I have connected the laser GND, 5V and PWM wires to the appropriate pins on the Duet 3.

@kchristopher it is unclear what you mean by conflicting. Do you mean the C setting? This is the pin name and you should use the one which matches the pin where you have connected the laser. The exp.... example is an example for a Duet 2 Duex board, if I remember correctly.
To check your full configuration, please post your complete config.g, e. g. to check whether you have set the mentioned M563 setting in https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_laser
