Does this work?

Hi!I'm currently building my custom 3d printer.Is it possible to have a 300x300mm heated bed supported by two linear rails and two lead screws?The linear rails sits on the sides at the back of the bed and the lead screws on the front.Is this a bad idea?I could post a picture of the model if needed. I just can't right now over the phone.

Post a picture,

I have seen many 3D Printers with 300x300 heated beds supported by two linear rails using dual lead screws.
So the answer it can be done.

oh yeah that's pretty normal.

Thought you meant an i3 style bed using using the screws to go back and forth - that would have been a bit weird :-)

Hi. I think it is possible. Because I have done the same.

Update:
I bought two extra linear rails. This should eliminate any potential wobble.
The four linear rails will go on the corners and the two leadscrews in the middle at each side of the bed.

Were do I buy aluminum beds?
Preferably 300x300 x 6mm.
I can't find any under 60$, witch in my opinion is quite expensive.
