It would be great if some annotations could be added to the C-beam build video about having to cut the aluminum extrusions for the frame to length. Yesterday when I started my build I ran into issues with the short ~250mm ones being slightly different lengths, so this morning I fixed these with a table saw. Unfortunately tonight I ran into another issue where the 500mm ones are actually 510mm and discovered this would not work when trying to mount the X/Z gantry after completing the build of the frame. So I had to take everything apart in order to do more cuts tomorrow. So a little annotation about ensuring all the short aluminum extrusions are the same length and at least 2 of the long extrusions are the same length as the X-axis C-beam extrusion would have been a big help to a newbie like myself.
