    20x20 extrusion worries me for a printer this size. I did a lot of stress analysis and positional error analysis due to bending under acceleration. For an X=450 Y=600 printer, I had to go to 30x30 extrusion for the X axis gantry and 40x40 for the whole frame including Y guides. If you intend to use 20x20 on a 600 wide X gantry, an acceleration of just 10000mm/s^2 will give you around 0.8mm of deflection which is a significant error on a 3D print. If you don't mind sacrificing speed for size, then it's an economic solution. Another problem I had was finding a bed heater for a large custom sized build plate. I eventually found Standard Keenovo Silicone Heaters who seem to know what they are doing. Don't underestimate the power required for heating a big build plate either. It will be over 1500W for a 600 x 600 bed!.The supports and thickness of the plate also become important over such a large size. I would recommend 8mm or preferably 10mm, and using one of the pre-ground cast Ally plates makes life easier. Good luck!

    Hey, thank you for the input. Yes, I'm a bit worried about the bed too and 8mm seems to be a better option. I got heavy inspiration from the veho 600. The lack of closed loop systems and the cheap way it was build motivated me to build my own. For the silicone heater, I got one of china.com for 45 Euros and I'm also in contact with Chinese 3d-printer manufacturers to buy cheap machined ALU beds. I see some potential in buying and selling that stuff, as am not the only one who wants to build big 3d-printers. I also made some changes on my printer for more stiffness.
