    So I have mechanically completed the build (this is at work so I can work on it in spurts). Just have to complete the wiring of the stepper drivers, power supply and work on setting up the smoothie board. I have the spoiler boards (not shown) but am considering pursuing a different type of spoiler board because there are some tools that can induce moisture in the area and I really don't want to be replacing MDF constantly.

    Hi PhotoSgt85, I'm interested in using something other than MDF for a base-plate as well. Aluminum would be ideal but pricey. Have you had any ideas for an alternative?

    My thoughts are to have a permanent aluminum base (either V-slot or just a plate of 1/4 or so inch plate. On this would be mounted a HDPE spoiler board. I have to look into it more but there is an Open Source recycling system called Precious Plastics that I would really like to utilize in general, and this would allow me to reuse spoiler boards as they are cut into. Recycling used 3D printer filament would also be optimal since we print a lot here for experiments. Basically I want to build an ecosystem in which I am capable of extremely efficient with materials and reusing what I can. This may not be for everyone, but I just keep looking at all the milk jugs and cat litter containers I am trowing in a recycling bin that I could be using productively. My XL will be almost exclusively used for aluminum and will be tried to be used for some sheet steel (front of 19" rack mounts), so I wanted a dimensionally stable spoiler with minimum moisture sensitivity as I will eventually add coolant flow.

    I decided to go with aluminum too.

    I love the look of an aluminum bed on these machines. Awesome jamesdjadams!

    I use HDPE in my small mill, love it!!! It's a bit pricey in the size you need though :eek: But you could make some cool stuff out of the leftovers ;)

    HDPE 1/2" x 24" x 36"

    Does it flex very much? I really don't know anything about HDPE. Based on the URL, it seems like strong stuff.

    I have plans for a HDPE spoiler board on my aluminum (vslot) bed. The best part is that after you cut into it a few times you can recycle it into another spoiler board. The recycling part will be a whole other projects though.

    It is pretty darn rigid, and I think at 1/2" thick you wouldn't see much if any flex. I have a piece 1" x 12" x 12" and I could stand on it and not see it bend, but of coarse 1/2" wouldn't withstand that much. I might have something similar at work, if so I'll see if I can bend or flex it by hand. What's the longest spread between supports on the XL?

    for the forces that the CBeam XL should see in the z axis I cant imagine 1/2" HDPE flexing any discernible amount.
