I don’t know how many people have creality based printers at home but they have finally posted their sprite drive on their shop page. Is it worth it, I dunno it’s pricey and I have no clue how it will connect to Ender3 motherboards as the Ender S1 has a whole different setup. I’ve asked them some question and see if they get back to me about the whole process of retrofitting existing Ender models.
