Alunar XY Axis Alignment braces

The Alunar is a great budget printer but the XY axis were not orthogonal and need to be squared up to produce more accurate parts. These parts mount on the front base plate threaded rods (inboard side of the base) and on the z axis guide rods at the bottom. Use a piece of 5/16-18 all-thread rod cut to 9.5 inches length and then use them to push or pull the X and Y axis into alignment. You will have to loosen the center nuts on the base threaded rods to allow the y axis to move and them re-tighte
