Currently building a C-Beam Sphinx with a total size of 1m x 1m. I am following Kyo's sphinx build to the letter except when it comes to the height of the y-axis side plates. I took the original y-axis side plate files from Kyo's "rev 2 folder" to a freelancer and had him scale them up a bit. So they are now 229mm x 155mm. Since i was going with taller plates i feared it would become more flexible, so instead of 6.3mm aluminium i went with 6mm steel. As i write this the plates are being cut at a local shop. Will update with pictures as soon as i get them. I have included the Y-Axis Side Plate (dxf) file in this post, free to download, just in case you want to go the same route. The picture below is my goal, except i will use a watercooled cnc spindle with a VFD.
