The original 3mm bed will warp - but I just dropped a level 3mm aluminium plate on that and never had any head drag or print level issues since.
The bed is a good way from the arms and even when I didn't know better and was using abs - the heat never effected the levelling.

I would even say that the 4 wheel levelling system is way better than the later 3 wheel system. So much quicker and easier to level with the wheel at each corner setup than the weird 2 at front 1 at back system.

I've got both so i do know :-)
Looks like someone just got burned
