For some time, I have been planning an MPCNC build, and today I ordered the kit of parts. I already have the EMT conduit, 3D-printed parts, and table parts.
I will update here when I have pictures.
Some information on my build:
I’m hoping you mistyped the aluminum conduit part. Aluminum won’t work.
That was a mistake, I had purchased steel EMT conduit. I updated the original post.
Built a table. Not really satisfied with it’s rigidity. I’ll probably put a sheet of plywood under the legs to stabilize it, maybe add some crossbars.
I have built several tables like this and diagonal braces are by far the biggest gain, even if they are thin. I use 2x2’s and they are more than plenty strong and stiff since the diagonal braces only experience axial loads.
Yep, either diagonals, or enclose the sides and back and put a shelf in it.
Whereabouts in Washington?
I was also planning to add a shelf.

Looks good! If you’re going to sheath the sides, you don’t really need the diagonals. Unless you’re using cardboard… 
I’ll revise my design and post the new version here in a few hours.
Here are all the parts I have currently:
Waiting until I get my conduit reamer to assemble the frame.
… and I got impatient and built it all anyway.
I will take off the XY motors and ream the conduits when I get my reamer. My electronics won’t arrive for another couple of weeks anyway.
I haven’t fixed anything to the table yet since my table surface is uneven. Sometime next week, I will buy the OSB and plywood to sheath the table, add a shelf, and replace the surface.
That looks great. The gray and white look good together.
Update: I have received my spindle (DW660), wire sleeving, and Raspberry Pi. Still waiting on my other electronics.
Update: I have received my endstops and started wiring everything. The only thing I am waiting on is the control board (SKR Pro), which should arrive relatively soon.
I have a new version of the table CAD, which I will be building:
