A metric ton. I should have caught on when I had to take out a loan to cover shipping costs. lol. But it is ok. This printer's frame is very sturdy. And it is going in with fiberglass reinforced gt2 belts. What is important here is that the nozzle is on plane with the bottom of the gantry And I can almost set that directly on the bed as my home. Then I can raise it to the top of the frame and enjoy the largest possible build volume.
