Hunting around the open builds store, I noticed that the dimensions for the Universal Gantry Plate are 20mm by 80mm. This must relate to the size beam it will fit? The plate is certainly much larger. Also, the C Beam page includes only the length, not beam width and height. Where can I find this information? Thanks Jim
From the C-beam page in the Parts Store: "C-Beam Linear Rail is considered to be a 40mm x 80mm profile which is compatible with all V-Slot Parts and Accessories"
In the download for the Solidworks parts library there is a section of pdf files that provides dimensions for nearly all the Openbuilds parts. The 20-80 universal gantry plate is not 20x80 but works with extrusion depths of 20mm through 80mm.
