30cm^3 3UP CoreXY (4 replies)

I'm slowly building up a printer based on the 3UP design. It is an HBOT but it looks to me to be a pretty easy mod to add the cross over and center attachment for corexy movement. My question at the moment has to do with the bed. Part of the modification is to have 3 lift screws rather than 2. The goal is to have a little over 300mm printable in each direction.

So the support I have now consists of two extrusions that are bolted in across the Z platform. I would like a bed that would heat up under a glass plate that is removable. Since the print area is a bit bigger than 300 I'm thinking about an aluminum plate heated with power resistors.

Here is where I am as of tonight:

Any suggestions? Pictures of something similar?

Thanks in advance,
