Hello forum I have installed a xxl smart controler on my robo 3d r1 printer, I have a question about all of the adjustments that you can do. The first and biggest is where can I find or get information about what all of the listed items do. i'm not much on making adjustments and hoping to see a change. If I could be directed to a site or page that could tell me the names and what what kind of change it would make if you adjusted it. That's like what do pid,s do what? and if i'm at the wrong location to ask this im sorry im still trying to get my feet wet on upgrades Thank Yall for all of the help i've gotten over the past few weeks.
