CR-10S PRO z height leveling block - direct x to y rails leveling for max precision

thingiverse

I'm looking for maximum precision while still achieving ease of use, and I found that leveling x to y rails would give me exactly what I need. To get the best of both worlds, I designed a one-piece block that will stay stable even when moving the z axis down, which is crucial since you'll need two hands to operate the two spindles simultaneously. The process is straightforward: 1. Disable stepper motors 2. Move the bed to the very front 3. Raise the z axis so the block fits under the beam 4. Place the block on the two rails 5. Lower the z axis manually until it sits perfectly parallel to the two lower rails 6. Use the printer control (or print server like octoprint) to raise the z axis for at least 30mm 7. Remove the block This design also makes easy printing without support possible. If you still prefer to have two separate blocks, I've uploaded a single-block design as well.
