I just upgraded my 60W laser with a Leetro controller to a Ruida RDC6445G so I could use Lightburn. Wow - what an upgrade! Things are sooooo much better now! I only have one small issue that may be a “feature” of the Ruida - not sure. I did a test engrave and noticed that the air assist solenoid can toggle extremely rapidly on some scans, depending on the toggling of the laser. I don’t see a setting to “always blow” like there was in the crappy Lasercut software. I would prefer to just have the air assist blowing all the time, or better yet, only toggling on/off at the start/end of each raster scan. I’m a little worried about frying the output of the controller if it is cycling the 24V solenoid multiple times per second.
