UPDATED MODEL :

Since this tool seems to be helping people get the bed aligned I made some updates and uploaded a new model. 

8/28/25 - Updates V2:

• wider hanger so the tool can be constantly rocked back and forth and stronger support so it does not flex as much up and down and left to right.
• finger hole to make usability much easier.

Print this one laying on its back no supports are needed.

When I received my Centauri Carbon, I noticed that during prints, the bed would move up and down as the print head moved across it. This is the automatic bed leveling system doing its job. However, I also noticed that the bed wasn’t very level.

After consulting the online manual, I found that it recommends tightening all four screws that hold the bed in place (this was not the case on my printer the screws were not completely tightened and not all set the same tightness). Following this instruction by tightening them all the way down, I ended up with a bed that wasn’t very level. To address this, I designed a very simple but effective leveling tool that mounts to the linear bars, allowing you to ensure your bed is properly leveled to the print head.

How to Use the Tool once its hooked on the linear bar:

1. Position the Bed
   Raise the bed until it barely touches the bottom of the leveling tool.
2. Check Each Corner
   Move the tool to each of the four corners of the bed, where the adjustment screws are located.
3. Set the Reference Corner
   Identify the corner that is highest and use it as your starting point. Adjust the bed height until the tool barely touches the bed.
4. Level the Remaining Corners
   Move to the next corner and adjust its screw until the tool just touches the bed at the same distance as the first corner. Repeat this process for all four corners.
5. Recalibrate the Printer
   Once all corners are adjusted, recalibrate your printer. This process reduces the amount of bed leveling corrections during prints

I level mine without the print plate attached but I expect it would work either way. So far, this method has improved my print quality and the reliability of bed adhesion.
