So after getting really excited about the MPCNC in October and ordering the electronics and hardware kit I have finally printed all of my parts and built the machine. However, I have encountered a couple of problems, the main one (and frankly the only one I care about) is that I don’t think my rails are perpendicular to each other. I have measured to make sure the corner blocks are the same distance apart on both x and y axis and that the measurement diagonally is the same. But when I move the X axis one end hits a corner block while there is a gap on the other side. The x axis is also kind of jittery compared to the y, but that could be due to incorrect belt tension.
I know the machine is just clamped to the table right now but the measurements all make sense. Plus it would be easier to fix now than when I screw it down to a board.
