The prints seem to be a bit more stable, and the installation was pretty simple.Be very careful what firmware you download.

Documentation is sparse, with a lot of leftover material from earlier, more DIY versions still clogging up the search results, but it is available, and the board's simplicity makes it unnecessary in most cases.As for the options, I bought it with the TFT35.

If you don't have OctoPrint, then this does have some features to run prints directly from the screen and it has an extra SDCard slot for loading prints into the screen. However, I would recommend saving your money on the TFT35 and spending it on a RaspberryPi, since OctoPrint is infinitely m
