Easiest Way to Find the Levitation Point

[3DXAV]

I purchased two Magnetic Levitation DIY Kits because I had this idea in mind for months: creating a levitating Goku. It was a project that took dozens of trials and errors, but seeing it floating at last was incredibly satisfying.

However, I quickly realized that making any 3D print levitate is much harder than expected. The magnetic force is so intense that even a tiny misalignment can cause the object to snap off violently — and potentially damage the base or the print itself.

At first, I tried everything, including 3D-printed centering tools like the one featured in the levitating pyramid model. While clever, these tools added more steps, printing time, and complexity.

Then, I made a discovery that changed everything:

Just use the black foam that comes with the kit.

Place the foam pad over the base, right above the center magnet. Set your model on top of the foam and start gently sliding it around. When it begins to slightly “rotate” in place or circle subtly, that’s a sign you’re near the sweet spot. From there, carefully remove the foam while keeping the model steady - and voilà! It floats.

Why this works so well:

• No need to print alignment tools
• The foam cushions any fall if the magnet rejects it
• You find the center intuitively and safely

When I shared this tip with another user, his reaction said it all (see attached screenshot). He had already printed multiple support structures and attempted over 300 times to get the levitation to work! One even opened a support ticket out of frustration.

This is why I felt compelled to post it here - I know many others might be struggling with the same issue.

So, if you’re using the Bambu levitation kit or a compatible one, try the foam method. It’s quick, easy, and way less stressful.

Hope this helps many of you!

I had my comment to you translated into Spanish using Deepl. It’s funny what happens when you translate it back into English

I still have an open ticket with Bambulab because my first MagLev kit was so badly calibrated that they sent me a second MagLev kit as a replacement. I got the second kit to work once. I printed two designs and both had placement helper. It just didn’t work.

With your method, first attempt: BOOM. It works.

Let the electronics cool down again, second attempt: Works again.

I also wrote to Bambulab yesterday in the ticket that they should take a look at your method and include it in their official description.

Thanks again!

Gracias a ti por darle validez bro! Yo también hablo español hahaha.

Ahora mi siguiente paso es ver como calibrar nuevamente los potenciometros del LevKit que dañé. Leí las advertencias mucho después! Y veo que a varios les ha pasado lo mismo, en la desesperacion por no lograr hacer flotar, tocan los potenciometros y luego no hay vuelta atrás, veré si puedo encontrar algun truco para esto tambien hahaha

Just to clarify, my native language is German I just noticed that you speak Spanish in your model and comments, including in response to my first comment. That’s why I translated everything else right away.

English as a second language is no problem, but for Spanish I need Deepl

As far as I know, it is no longer possible to calibrate it yourself without the appropriate measuring tools. My first kit also has a small (compensating) magnet stuck to one of the coils, which I once dropped when the base banged against the magnet.

Hahaha oh I see, still I appreciate the effort of translating. The good thing is that Makerworld automatically translates comments.
As for the calibration, I was thinking of using my multimeter to measure the frequency of the potentiometers that are working fine, then try to match that frequency on the other kit I messed with, and later share the data here in the forum
