Cool, you got OctoPrint running on the SM2 touchscreen? I like! From the hardware spec’s it is indeed not the most powerful device ever…
I am just wondering, also taking your other post Printer malfunction and exploring touch screen android into account, if you could reverse the game and replace the tocuscreen with a used, more powerful smartphone and put Snapmaker’s apk’s on that one… Of course it would be necessary to reverse-engineer the USB-C-wiring, but my guess would be that this is basically just power and USB OTG. I suppose that on the main SM2 Controller there’s just an USB hub which exposes the USB-A port and also has an USB-to-UART bridge built-in.
