I alomst ordered the printer, but then I saw a post on reddit with a document of a new revision.
They upgraded the pulleys, the aux fan is now screwed (no glue anymore), the board cooling fan has now ball bearings, longer linear bearings on Z axis, some changes at the base, new red laser for LIDAR and they changed the wiring for the heated bed.
My Question is now, how can I be sure to get this revision of the printer?
