Hi Jack,
That’s interesting, well, based on Ruida settings at min power 20% and max power 80% I have listed below the test values sent from LightBurn (in ‘Line’ mode with min and max power the same) along with the corresponding power values I would expect the PWM signal to be delivering to the power supply - which I have confirmed to be correct on a scope.
If you get the chance to check some of these other values from your system just to confirm what is happening for you I would appreciate it. And let me know the firmware version you are running.(Edit>Get Controller Info). I’m running a RDC6442G with v8.07.70.
The 80% reading will be interesting for you to check since the value we are both expecting is wildly different!
Thanks.
Cut Settings % power Vs. Ruida actual output power %
0 = 20
10 = 26 (you reported 20% here?)
20 = 32 (are you expecting 20% here?)
30 = 38 (are you expecting 30% here?)
40 = 44
50 = 50 (you got 50% here but that is also what I was expecting 
)
60 = 56
70 = 62 (presume you get 70% here?)
80 = 68 (presume you get 80% here?)
90 = 74 (you reported 80% here?)
100 = 80
