Celestrius - AI that solves 1st-layer issues without a LiDAR

· 4 min read

Celestrius is an AI model that uses a simple nozzle camera instead of a LiDAR to tackle a slew of notorious 1st-layer issues: under/over extrusion, bed adhesion problem, wrong z-offset, you name it.

What is Celestrius?

One of the innovations by Bambu Lab's X1 is a LiDAR that watches the 1st-layer for potential print issues.

On one hand, the Obico team is excited to see a new, innovative solution promised to address the issues that cause endless headaches to even the most-experienced 3D printing enthusiasts.

On the other hand, we don't believe LiDAR is an optimal choice for this task. The reasons are:

  • LiDARs are proprietary, expensive, and hard to source. This is a walled-garden solution that isn't aligned with the maker ethos deeply rooted in the 3D printing community.

  • AI technologies centered around cameras are advancing at a much faster pace than those for LiDARs.

  • LiDARs are for robots only. Cameras are for both robots and humans. Who doesn't enjoy watching a jaw-dropping video like this?

That's why the Obico team started project Celestrius - an AI model that will be a lot smarter than our current one simply thanks to the nitty-gritty detail a nozzle camera can reveal.

Well, this is the hope at least. In reality, we are not there yet because this project is damn hard! After tens of failed experiments, hundreds of print hours to collect data, and thousands of cups of coffee (Ok, may not be that much coffee. But you get the point), we now need your participation to push this project over the finish line.

And this is why we have now opened a limited pilot for project Celestrius.

The PrusaSlicer is quickly becoming one of the most popular slicers in the community. It is now one of the top 3D printing slicers due to its simple interface, lightweight design, and boatload of sophisticated capabilities.

The last PrusaSlicer 2.5 update added new features like the Lighting Infill and Arachne Perimeter Generator, to name a few. These were wonderful additions that were positively accepted by users.

The latest version, PrusaSlicer 2.6, kicks things up a level by including a slew of long-awaited features.

Read on to find out about its new features and how you can "support" your 3D prints in a better way with this upgrade.

What’s new in PrusaSlicer 2.6?

PrusaSlicer's 2.6 alpha 2 version was released a few days ago. The PrusaSlicer 2.6 is now available to the public for the first time (alpha 1 was only tested internally).This was the first time that people in the 3D printing community could use 2.6's new features. Let's take a closer look at them.

Klipper is an advanced 3D printing firmware that gives you a high level of control over how your 3D printer moves. One key part of this control is the measurement and management of your stepper motor's motion. Klipper does this with the help of the Rotation Distance parameter.

Rotation Distance measures how far your print head moves in a single rotation.This value has an impact on the dimensional accuracy and appearance of your prints. and, in turn, is a key factor in determining the final quality of your 3D models.

In this article, we'll talk about what the rotation distance means in Klipper and how you can use it to get the best prints possible. We'll talk about it in detail and go over the steps for setting up the rotation distance for your 3D printer.

Read on to learn how to 3D print highly accurate parts and take your printing to the next level.
