Yeah, its a bit of a pain if thats what it requires. Luckily none of the ones I’ve worked on so far have been off by more than a millimeter across the bed and thats acceptable to me (at least for where these machines are going) for bed leveling to do the rest so I havent opened up the bottom on any yet. Solid machines printing wise though! Been incredibly impressed so far despite hit or miss reviews online, only failed prints I’ve had are from met arranging models poorly. And no worries, best of luck with the machine!
