Tonight I printed a couple of these little friends to help align/fine tune the xy carriage rods parallel to their axis. They work surprisingly well (beginners luck?) so i uploaded them to Thingiverse. Maybe somebody might have a benefit from them too. To help align the xy carriage axis, just clamp two helpers to each side of the rod. then tighten the belts and pulleys. The print head should now move quite easy when lubricated.
Please note this is my first ‘design’ ever. I had to tweak the output size (.stl is already scaled) a little to print them on the correct size for my Vertex rods.
These work just fine! I have to get 3 of these printers back in shape. With the help of these two are done and the third should be done tomorrow. Thanks for sharing the file.
