Welcome to the SeeMeCNC Community

I think you should add a few more maximum bed sizes for the literature. I constantly hear that an Orion can only do a 4.25" square maximum. No one thinks about the rectangle size, so i think you are losing some customers.

I think you should add a few:

1) 4.25 x 4.25 square

2) 4.0 x 6.0 rectangle

3) 6.25 diameter circle

I have been making alot of iPhone 6 cases, and most people think the Orion can't do that size.

I'd assume that the reasoning behind their published spec is to have a number comparable to all of SeeMe's Cartesian competitors that can only do rectangular build areas. Right now the website says:
6" diameter by over 9" tall cylindrical build volume (appx. 175 cubic inches)
5" Square by 9" tall box shaped build volume
Which covers 2/3 of the bases that you touch on, even though the numbers are slightly different.

I was thinking more of this one:

Build Area
Maximum Printable X/Y Area 6" Diameter (150mm)
Maximum Printable Square Size 4 1/8"" (106mm)
Maximum Printable Z Height 9 1/4" (235mm)
