I rescently bought myself a nextion 7" touchscreen(which has 4 wires coming out of it, (5V, Ground, RX, TX)), which I intended to use together with a Ramps 1.4 mounted on a MEGA 2560. And (needless to say perhaps?) I haven´t gotten it to work, at all. NOTHING works for me as intended, as a matter of fact, which is not only annoying as H–L, but also rather depressing.
NOW, yesterday, I stumbled across this BRIGHT and MAGICAL beam of light, called DuetWifi, which I do intend to purchase ASAP! Either I will run it with PanelDue, OR with this Nextion-screen, that I allready own.
Should mention, that I AM somewhat of a novice, when it comes to both 3D-printing, and electronics. I also have next to NO knwledge when it comes to writing code!
On the other hand, what I DO HAVE, is a DREAM/VISION...!!! ::-))
Can anyone tell me, whether DuetWifi and my Nextion-screen are compatible? And if they are, could anyone PLEASE help me out linking them together and making them work, as intended? Is there some way to make these two devices to interact with eachother? Also needless to say, I WOULD BE FOREVER GRATEFULL towards anyone who could/would help me out with this issue! IF NOT, I will buy the PanelDue, which on it's own seems as a VERY capable product.
Otherwise I´ll have to wait for my Raspberry Pi III to arrive, (comes with a smaller touchscreen attached), and set it up with the Nextion, just to make use of it, making it "not just another NOT thought-thru purchase from me...

ANY not misleading information, would be concidered help in the RIGHT direction for me!

Glad for ANY HELP!
