Klipper firmware has been around since 2016 in the 3D printing community. It’s free, open-source, and has steadily become a mainstream 3D printing firmware, second only to Marlin.

Yet, Klipper’s earlier versions missed key features like the Octolapse, Exclude objects, and plug-in integration found on Octoprint and Marlin combo. This lack of certain valuable features restricted users from using Klipper as their primary 3D printing firmware.

However, since the recent updates, some of these features are slowly making their way into the Klipper firmware. For example, you can now shoot Octolapse-like videos on your 3D printer using the Klipper timelapse.

Likewise, Klipper now also supports the Exclude objects functionality to rescue you from failed prints. But, it needs some initial setup and configuration, which might be puzzling to new Klipper users.

So, this article will take you through the entire process of setting up Exclude objects for your Klipper 3D printer. We’ll look at this feature in detail and understand how you can use it in your 3D printing workflow.

Let’s exclude the failed prints.

If you are new to 3D printing, we are sure you have encountered numerous print failures. Thankfully, this is not something new or unique. It happens to even the most seasoned users. But obviously everyone wishes to improve their 3D printing skills and so knowledge of 3D printer failure detection becomes essential, and this is exactly what we will cover in this article.

3D printing and failures​

Because 3D printing is rapidly becoming popular in a variety of industries, it is critical that every student, as well as manufacturing and design professionals, understand the technology. Though you may not need to understand its complexities, having a working knowledge will help you in your career.

3D printing is a manufacturing process that converts a digital CAD file into a three-dimensional physical model by layering thin layers of material one on top of the other. This is also known as additive manufacturing because material is added rather than removed, as is the case with most conventional technologies.

However, 3D printing is still in its early stages and thus prone to failure. DIY and desktop 3D printing, in particular, frequently fails, and users must use a trial-and-error approach to eliminate or reduce failed prints.

We are all aware of how critical, yet difficult, it is to level a 3D printer bed. All of your prints will fail if you don't have a level bed, wasting your time, materials, and money. Even having an auto-bed leveling feature is not always sufficient, and your prints may still fail. To solve this issue, OctoPrint's Bed Level Visualizer plugin is the only tool you need to easily level your print bed.

To help you understand this useful OctoPrint plugin, we've written a complete guide on the Bed Level Visualizer to help you set it up quickly and eliminate your bed leveling issues.

What is the OctoPrint Bed Level Visualizer Plugin?​

Bed level visualizer is a useful OctoPrint plugin that converts the bed topography report into a comprehensive 3D map to show the varying elevation (height) across a 3D printer bed, assisting users in leveling the same. This plugin also assists you in determining whether your bed is warped or simply tilted. Thus, the bed is leveled by carefully tightening or loosening the leveling screws at peaks and valleys respectively, to make it as flat as possible for a successful print.

The Bed level visualizer plugin was created by jneilliii (GitHub page). This plugin was installed on at least 35.84k instances in the previous month (August 2022), with at least 759 new installations in the previous week (at the time of writing this article).

The core of 3D printing is a 3D model. 3D modeling for 3D printing is important as all 3D prints start with a digital CAD model that is "sliced" in a slicing software which the 3D printer prints. Being an integral part of 3D printing, having a working knowledge of 3D modeling and the various tools becomes crucial.

In this article, we'll go over the fundamentals of 3D modeling for 3D printing, as well as the distinction between inorganic and organic 3D models, and the popular software for each type.

We've included 3D modeling software for beginners for those on a low budget, as well as a few high-end options for professionals.

But first, to make sure we're all on the same page, let's go through the fundamentals of 3D printing.

3D printing, also known as additive manufacturing, is a method of creating three-dimensional objects layer by layer using a computer-aided design, or CAD. 3D printing builds objects by layering materials such as polymers, composites, or biomaterials that vary in shape and size, as well as rigidity and color.

Even though 3D printing isn't new, there are some who will benefit from our guide to the most common 3D printing terms for beginners.

Regardless of the 3D printing technology being used, it all starts with a 3D CAD model. In this article, we will go through the fundamentals of 3D modeling and its different types, with a focus on 3D printing.

To further help you in selecting the best CAD software for your 3D models, we will also list out a number of 3D modeling software suitable for both beginner and advanced users.

So let's jump in!

Klipper is one of the few 3D printing firmware that natively supports an external camera for monitoring your 3D printer. Klipper’s web interface makes it easy to attach a camera to the Raspberry Pi and monitor your printing progress.

But Klipper is a relatively new firmware with limited resources and guides detailing its various features. As a new user or beginner, it’s easy to get confused about the installation and configuration of a camera on your Klipper 3D printer.

This article aims to make this process easy for you and help you set up a camera on your Klipper-connected 3D printer. Read on to learn in-depth about Klipper’s camera setup procedure and how a camera can benefit your 3D printing workflow.

Introduction​

Using the timelapse feature in Klipper, you can record your entire 3D printing process and share bits of it on your social media platforms. These videos are also a great tool to analyze print failures and pinpoint the causes behind a failed print.

Yet, despite their usefulness, setting time-lapse videos in Klipper can be challenging for several users. And while it's a relatively easy setup, the initial configuration can confuse beginner Klipper users easily.

In this article, we'll simplify this process for you. We'll go over the entire procedure step-by-step and configure the timelapse functionality for your Klipper instance. By the end of this guide, you'll be able to record picture-perfect timelapse videos of your 3D prints and share them within your social circle.

Let's start shooting.

Nozzle Scraping Bed Surface​

What Is It?​

Inaccurate bed leveling, low initial layer height, or incorrect Z-offset settings can cause your printer's nozzle to scrape against the printing bed. It might damage the nozzle and the print bed and restrict the filament from flowing out of the nozzle.

If left unchecked for a while, it can build up pressure in the hot end and cause the extruder motor to skip steps. Nozzle scraping is relatively minor but one of the most common issues faced by beginners and new 3D printer users.

Blobs or Zits​

What Is It?​

Blobs or Zits are the tiny dots on your print's surface and directly affect its overall quality and appearance. These are often the result of incorrect retraction settings or high printing temperature and negatively affect the surface finish of your 3D printed part.

Sometimes, you can easily remove them with sanding, but big blobs can be challenging to remove and may leave an impression on your parts. For this reason, it's best to tune your printer to not create them in the first place rather than try to remove them through post-processing.

Broken Filament​

What Is It?​

The filament is a relatively fine plastic thread, which can break easily under certain conditions. If your filament breaks mid-way during a print, it will cause a print failure leading to a loss of print time and effort.

Filament usually breaks due to poor quality control, high humidity, or extreme tension in the filament path. These conditions are essential to consider if you're planning to print large-sized objects or want to use your printer for batch 3D printing.
