and the difference between how RuiDa controls the LPS is different than how GRBL controls the LPS yet they get the exact same results? GRBL has LPS-IN tied to 5V and doesn’t change no matter what design is created in LightBurn using all types of output types from dithering to grayscale raster engraving to fixed power settings for vector lines. The user never goes in a changes LPS-IN level ever and the GRBL controller only does active control on LPS-L but you don’t recognize this as a single control line systems vs RuiDa which actively controls both signals going into the LPS for every design?
If internally the LPS output laser driving circuit results in the same exact laser power control no matter if the 2 inputs are controlled dynamically like the RuiDa and no matter if only LPS-L is dynamically controlled while LPS-IN is held to a fixed level I’m all ears. Maybe RuiDa uses the 2 lines because they like to charge more and it might seem more expensive if 2 wires are connected instead of just 1.
You do understand that is is NOT how RuiDa controls the lasing process right? If the design or firmware calls for 50% laser power then the LPS-IN signal is pulsed to 50% duty cycle while the LPS-L hold low for the duration of the pixel period.
that’s why I was pretty much ignoring it. I suppose I should have tried to figure out what “laser macros in a user friendly package” meant. But when he then goes off and shows doing it in GRBL I was thinking WTH there’s no benefit if both do it.
