Z axis calibration help

thingiverse

After some prints and tests, I discovered that the Z-axis was no longer synchronized. This wasn't a surprise, given that we have two stepper motors for the Z-axis, and they can become desynchronized over time. As a result, I misplaced the Hotbed. After adjusting the caliper and folding rule, I was dissatisfied with the outcome and created this small helper tool. You only need a folding rule to create it. I dissected the folding rule at 10.5 cm (you can make it longer if you prefer) and inserted it into the holder. Assemble it, finish. Now I can check the Z-axis before each print. If you have any issues or improvements for this tool, please let me know. It's very easy to control and adjust the Z-axis with this setup. Here's how to do it: Step 1: In the Printer menu, go to the "Quick Settings" menu and select "Home All." Check if the Z-axis is level on both sides. If everything is okay, you only need to perform bed leveling. Step 2: If the Z-axis is not level, go to the "Quick Settings" menu and disable the stepper motors. Now, turn only the right threaded rod to adjust the Z-axis to match the left side (where the Z-axis end switch is located). If the Z-axis end switch is on the right side, adjust the left threaded rod instead. Test the level with the "Home All" function. If everything is okay, you only need to perform bed leveling. Repeat Step 2 if the Z-axis is still not level. With this little tool, you won't need to adjust the Z-axis end switch.
