Downloading Print.Test.Page.OK 3.0112/29/2023 I'll be running some test prints later and post the results. Lastly I had to adjust the stepping in the firmware, since this screw moves 4mm for every revolution, so the new number is Z800 I'm gong to look into making another one, probably out of aluminum. On a side note, the quality of the printbed frame is really below par, and mine is warped to boot. I might eventually go ahead and replace the busings, but for now I'll leave them alone. I was originally thinking about installing some linear bearings for the guide rods, but It turns out the rods are 3/8" diameter (9.54mm), and the bearings I have are 8mm. The ball screw installed without any glitches using the 4 original countersunk screws and lock nuts, the support rods got lined up and everything is back together. Once the part was printed and test fitted, I disassembled the print bed again, cut away the wood mount and installed the new plastic mount. No problem, I desinged an adapter plate, re-assembled the printer with the original parts, and printed the new part. So I needed an new adapter plate, but the printer was in pieces. I disassembled the print bed and motor, only to find that the original mounting plate was too small to accommodate the large flange pf the ball nut, not only that, the new nut is too tall and has a 32mm diameter shaft, and would hit the rear "Y" shaft before hitting the end stop. The bottom connects to the existing motor via a 5mmx8mm flex coupler, while the top rides inside a 608 bearing. I bought a SFU1204 x 350mm ball screw on eBay, and when I received it I had a friend machine the ends down to 8mm. While the well nut idea was sound, and kept me going for the last couple of months, i still wanted to go "all the way" and install a ball screw instead of the 5/16" threaded rod. That helped quite abit, nough so that the banding was 85% gone, but still there if you looked close. My first attempt at fixing the problem was with the well nut installation which I detailed in another post. When I originally bought the Solidoodle 3, I had quite a bit of banding on my prints.
