Have you had requests to do a version of your firmware for the Creality CR-10S Pro (this has a color touch screen as well). There are thousands of users out there who can’t get firmware updates (Marlin 2, BLTouch, EZABL, etc.). I think that community would be very willing to pay for a version of your ADVis++ for the CR-10S Pro.
I get many requests to adapt to many printers. It is too difficult to adapt without the hardware and I do not plan to buy a Creality printer. For the moment, I prefer to continue with Wanhao ones.
And of course, anyone is free to make a fork of my work to support other printers. It is GPLv3 (for the Marlin part).
