Le firmware Klipper est très apprécié ces derniers temps pour sa large gamme de fonctionnalités et ses performances exceptionnelles. Il offre également plusieurs options de configuration pour calibrer votre imprimante et obtenir des impressions 3D de haute qualité.

Aujourd'hui, nous allons configurer un paramètre crucial : le réglage PID de votre imprimante 3D. Un réglage PID correct garantit que la buse et le plateau d'impression chauffent le plus rapidement possible et maintiennent la température de consigne avec une grande précision.

Cet article vous guidera pas à pas dans le processus d'étalonnage PID de votre imprimante 3D à l'aide de Klipper. Il vous permettra de mieux comprendre ces paramètres PID et de résoudre tout problème de surchauffe de votre machine.

Introduction​

Pressure Advance in Klipper is designed to compensate for the side effects of instant speed changes that occur during fast print speeds. It reduces stringing, gives your prints sharp corners, and delivers a high print quality even at speeds above 100 mm/s.

But tuning pressure advance in Klipper and understanding its functioning can be puzzling to new Klipper users. So, in this article, we’ve gathered all the information you need to know about Pressure advance and set it up in Klipper. It’ll help you understand the benefits of this feature and how you can use it to sharpen up your 3D prints.

Let’s Advance!

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.

3D Printer Failures/Courtesy: Fabbaloo

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.

Creality's Ender 3 3D printer is one of its best-selling models, and it's popular among students, enthusiasts, and hobbyists. As a result, it is safe to say that Ender 3 users are mostly hustlers looking for ways to get the most out of their 3D printer. Many users do not see the need to connect a camera to their 3D printers, but it can greatly improve your 3D printing experience. Many feel that installing. Camera is a tedious task but it is not so. In fact, it is quite easy. All you need is a good camera and a camera mount. This article discusses the various Ender 3 camera mounts that can be installed on your 3D printer.

Klipper est l'un des rares firmwares d'impression 3D prenant en charge nativement une caméra externe pour la surveillance de votre imprimante. Son interface web facilite la connexion d'une caméra au Raspberry Pi et le suivi de l'impression.

Cependant, Klipper est un firmware relativement récent, avec des ressources et des guides limités concernant ses différentes fonctionnalités. En tant que nouvel utilisateur ou débutant, il est facile de se perdre dans les méandres de l'installation et de la configuration d'une caméra sur son imprimante 3D Klipper.

Cet article a pour but de simplifier le processus et de vous aider à configurer une caméra sur votre imprimante 3D connectée à Klipper. Poursuivez votre lecture pour découvrir en détail la procédure de configuration de la caméra Klipper et comment elle peut optimiser votre flux de travail d'impression 3D.

Introduction​

Grâce à la fonction timelapse de Klipper, vous pouvez enregistrer l'intégralité de votre processus d'impression 3D et en partager des extraits sur vos réseaux sociaux. Ces vidéos constituent également un excellent outil pour analyser les échecs d'impression et en identifier les causes.

Pourtant, malgré leur utilité, la création de vidéos en accéléré dans Klipper peut s'avérer complexe pour de nombreux utilisateurs. Et bien que la configuration soit relativement simple, les réglages initiaux peuvent facilement dérouter les débutants.

Dans cet article, nous allons simplifier ce processus pour vous. Nous détaillerons la procédure étape par étape et configurerons la fonctionnalité timelapse pour votre instance Klipper. À la fin de ce guide, vous serez capable d'enregistrer des vidéos timelapse d'une qualité exceptionnelle de vos impressions 3D et de les partager avec vos proches.

Commençons le tournage.

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.
