One last thing: if you’re printing as a hobby or for home use, I suppose you can get away with the aluminum foil tip method and leave it like that. But if you’re using your printer strictly for work—like I do—don’t assume the setup is a “set it and forget it” deal. Unlike the Creality HI (which I own)—which has a rock-solid, incredibly rigid bed—the Sparkx i7 has a flexible plastic bed mounted on springs. While the HI’s bed mesh stays consistent over time, the Sparkx bed is so pliable that the mesh varies constantly—day by day, even hour by hour—eventually drifting out of alignment. So, if you plan to do a lot of printing, especially large or important jobs, make sure to check the bed mesh periodically; don’t just neglect it.
