Now that the second print failed without any external disturbances I decided to update my tech stack.

I just ordered a #RaspberryPi 5B + new USB cable (this time with power blocker instead of manually taping the pins) + new case + new official power supply.

Let’s hope this will be fixed …

The fun thing is: The printer was connected the whole time. At one point it just completely stopped doing anything, turned off all motors didn’t even move the hot-end into parking position.

#3DPrinting #Octoprint

Bonus points if the CAD can also do CAM #3dprinter #octoprint #cura #slicer

I need a better #3dprinter workflow. Currently Fusion 360 => Cura => Octoprint

Octoprint is rad so happy to leave that.

Cura is fine, but I would love to be able to share settings between computers (OSX and Linux)

Fusion 360 can go in the bin, but I do love the one click push to Cura (ie no intermediate download STL step).

I have an old Lulzbot Mini One

Suggestions: Go!

Turn Your 3D Printer Into a Smart Machine: How OctoPrint Changes the Game

1,347 words, 7 minutes read time.

If you’ve ever found yourself baby-sitting a 3D printer for hours, wondering whether your print is still going smoothly or if it’s failed somewhere mid-layer, you’re not alone. Most 3D printing enthusiasts—especially guys who love tinkering, hacking, and squeezing every bit of performance from their machines—have hit this roadblock. But there’s one tool that’s quietly become the secret weapon of serious makers: OctoPrint. This open-source powerhouse transforms a standard 3D printer into a remotely managed, visually monitored, and fully customized smart machine. In this deep-dive, we’ll explore how OctoPrint works, how to set it up, and why it might be the most important upgrade you can make to your 3D printing setup.

OctoPrint was developed by German software engineer Gina Häußge, and it’s been steadily growing in popularity since its launch. What started as a personal project has become one of the most essential tools in the 3D printing world. According to the official site, it’s now used by thousands of makers worldwide to manage and monitor their prints from any browser. OctoPrint runs on a small single-board computer—most commonly a Raspberry Pi—and connects to your 3D printer via USB. Once set up, you can access it through a web interface, giving you control of everything from temperature settings and file management to live webcam streams of your ongoing prints.

Setting up OctoPrint isn’t rocket science, but it does take a bit of prep work. First, you’ll need a Raspberry Pi (the Pi 4 is recommended), a microSD card, a decent-quality power supply, and a USB cable to connect to your printer. Many users also add a webcam to monitor prints visually or create slick time-lapse videos. The installation process typically involves downloading the OctoPi image—a Raspberry Pi-compatible version of OctoPrint—from the official OctoPrint site, flashing it onto the SD card using software like BalenaEtcher, and then configuring your Wi-Fi and printer settings through a simple text file before booting the Pi.

Once everything is plugged in and powered up, you can open your browser and head to “http://octopi.local” to start setting up. The first-time setup wizard will walk you through steps like creating a user account, configuring basic printer settings, and enabling access control. It’s fairly intuitive, and if you run into any snags, there are dozens of excellent community resources, including guides from All3DP and Raspberry Pi Foundation.

What truly makes OctoPrint shine is its feature set. Once installed, it acts as your 3D printing command center. You can upload G-code files directly from your computer, start and stop prints remotely, adjust temperatures in real time, and even pause or cancel prints if something goes wrong. Add in a webcam, and you get a live video feed of your printer that you can access from your phone or computer anywhere with internet access. For makers who want control and oversight, this is a game-changer.

Another standout feature of OctoPrint is its plugin ecosystem. There are hundreds of plugins that allow you to tailor your OctoPrint experience. The OctoPrint Plugin Repository hosts an array of extensions, from visual enhancements to performance tools. For example, Bed Level Visualizer gives you a detailed view of your print bed’s flatness, helping with better adhesion and fewer print failures. PrintTimeGenius improves estimated print durations with startling accuracy, a small upgrade that goes a long way in planning your printing sessions. Want cinematic timelapses? Octolapse creates buttery-smooth videos that are social media gold. If you’re concerned about security and cloud access, plugins like Obico (formerly The Spaghetti Detective) even let you monitor and control prints from anywhere while detecting print failures using AI.

The beauty of this plugin system is that it scales with your needs. Whether you’re just starting out or you’re managing multiple printers in a print farm setup, OctoPrint has you covered. Resources like Obico’s blog and 3D Print Beginner provide great lists of must-have plugins, many of which are completely free and updated regularly.

Beyond technical capability, OctoPrint also excels at usability. The web interface is clean and responsive, designed for efficiency. You can upload, organize, and manage print jobs right from the browser. For guys who are used to digging into firmware settings and SD card juggling, this is a breath of fresh air. The interface is also themeable thanks to plugins like Themeify and UI Customizer, allowing you to tailor it visually to your taste. Whether you want a dark mode, a sleeker dashboard, or just larger icons, there’s a plugin to do it.

Now let’s talk performance. OctoPrint won’t magically speed up your printer, but it dramatically speeds up your workflow. Uploading files wirelessly, adjusting settings mid-print, monitoring progress from your phone—these are quality-of-life upgrades that save hours over time. In setups where printers are running constantly, like in Etsy shops or small-scale production businesses, OctoPrint’s automation features and ability to manage queues become invaluable.

Security is another topic worth discussing. Since OctoPrint runs on your network and can be accessed remotely, it’s important to set it up correctly. Always enable user authentication, and consider installing a firewall plugin or VPN for extra protection. Resources like OctoEverywhere provide smart advice on keeping your setup safe while enjoying remote access.

The community around OctoPrint is one of its strongest features. Whether you’re troubleshooting an issue, trying to write your own plugin, or just want to show off your latest timelapse, you’ll find support on the OctoPrint Community Forums, GitHub discussions, and Reddit’s 3D printing threads. The community is active, helpful, and filled with makers who’ve encountered every problem under the sun.

Troubleshooting and advanced customization are also major parts of the OctoPrint experience. For example, you might run into issues with camera lag, plugin conflicts, or Wi-Fi stability. Forums and tutorials from Instructables and Prusa are great places to start. Common advanced tweaks include adding custom LCDs, scripting automated bed probing, or integrating OctoPrint with home automation platforms like Home Assistant.

Let’s not overlook aesthetics and user experience. With plugins like OctoDash or TouchUI, you can even turn a touch screen connected to your Pi into a standalone printer control panel. This is a favorite feature among guys who love building custom enclosures or want their printer setups to look as good as they perform.

Looking at the bigger picture, OctoPrint isn’t just a tool—it’s a philosophy. It embodies the DIY spirit of 3D printing. It’s open-source, customizable, and endlessly extensible. It’s built for people who love to tinker, improve, and share what they learn with others. And when it comes to getting the most from your 3D printer, especially in terms of convenience and control, there’s really no competition.

If you’re serious about 3D printing—or if you just want to stop hovering over your printer every time you hit print—it’s time to give OctoPrint a serious look. Visit the OctoPrint download page, gather your components, and dive in. You’ll quickly realize why so many people consider this the most powerful upgrade you can make to a 3D printer that doesn’t involve changing a single piece of hardware.

We want to hear from you—are you already using OctoPrint, or thinking about diving in? Share your setup, tips, or questions in the comments below. And don’t forget to subscribe to our newsletter for more in-depth guides, reviews, and updates straight to your inbox.

#Octoprint #Achievements

Screenshot of the "Weekend Warrior" achievement in Octoprint.

@castaway I just know one is more screen reader accessible than the other, #OctoPrint gets a considerable edge over Fluidd. Unfortunately, it isn't compatible if Klipper has been altered in any way at least from what I tried to do so I'm forced to use Fluidd's interface with all of its great information but lack of labels for most if not all their controls.

Not gonna lie, #3dprinting folks. We don't know how all of this software related stuff works. What is Fluidd? Why does it exist? What is #octoPrint and what does it do if Fluidd is already a thing? I know it does a hell of a lot for #accessibility but we've already bricked our printer once, we don't want to do it again.

OctoPrint ist aktualisiert. Das war sehr einfach.
Jetzt kann der Pi wieder an sein Netzteil, von dem ich ihn frecherweise mitgenommen hatte. Er hat sich beschwert.

#3DDruck #octoprint

Fuck it, that’s fine! 🙃 … And it just took me almost 2 hours.

Auto-home, create mesh, adjust knobs, repeat.

It’s really hard to level 9 points in a 3D space when you can control only 4 of the points but all of the points are on the same plane. I also have a feeling that my print bed is slightly uneven.

But the total difference of 0.119 millimeters is very much below my usual layer height of 0.2 millimeters.

… and it is only the base bed leveling. The mesh is used by the firmware to even out the layers by adjusting the nozzle height above the print bed.

#Ender5pro #BLtouch #3Dprinting #OctoPrint #BedLevelVisualizer

Ages ago I installed a #BLtouch on my #Ender5pro and always do a leveling for each print, which never failed me.

Recently I messed with the physical leveling of the bed by changing the screw positions and eyeballed the leveling (screw all four screws hand-tight in,and then unscrew them by 3 revolutions each).

And I just checked ... a difference of shy over a millimeter. I think I did a pretty good job by just looking at the distance between the nozzle and the bed.

Visualization is done by the awesome OctoPrint-BedLevelVisualizer plugin for #OctoPrint. For my printer, this #gcode configuration properly creates the mesh visualization without manually modifying any of the printer's settings.

M190 S80            ; Set bed temperature
G28                 ; auto-home all axes
@BEDLEVELVISUALIZER ; monitor output for level data
G29                 ; probe for bed levels
G1 X0 Y0 F2000      ; return print head to home
M140 S0             ; turn off print bed
G91                 ; relative mode on
G1 Z60              ; lower print bed by 60mm
G90                 ; relative mode off

You might want to change the bed temperature to a value you usually use (M190 S80 where 80 is the temperature)

In the wiki they say use M420 V to store the created mesh, but this is what G29 with BLtouch already does.

The last three commands are purely aesthetic.

... and now I'm going to turn some screws 🙃

Yea, the darkness is really "looking great" 🙃

Took me a bit but I managed to get all 4 of my cameras working with @octoprint again. Because I am incapable of doing things the easy way, I'm using an RPi 5 and there are no octopi images with the new camera stack for that yet. I am using 2 Arducams that need a custom mjpeg-streamer from Arducam plus a USB camera and ESP Cam. Had to edit Arducam's custom webcamd a bit, too.

OctoPrint does run much better w/octopi instead of manually installed on top of Raspbian.

#3DPrinting #OctoPrint

Now that I've moved over here to Hachyderm, I suppose it's time for a new introduction.

I'm a mechanical engineer and cyclist that is interested in just about everything and constantly learning. My project list is forever growing, but most of it is taken care of by #FreeCAD, #octoprint, #3dPrinting, #python, #obsidian, and a variety of other #foss tools.

I'm also a #bluegrass and #ska musician, playing #guitar, #UprightBass, and #mandolin. I never said I was great, but I have a lot of fun making music.

I like to try and help people wherever I can because a lot of people have helped me over the years. The #fediverse is full of wonderful people, and I've learned so much and had such positive interactions with people from all over the world since joining in 2022.

Let's keep it going!

I have contacted Qidi support about our #3dprinter #OctoPrint issue. Several posts on different places including the OctoPrint forums say it is possible to connect Qidi printers, including the q1pro to OctoPrint. We will figure out a way, now is far from the time to give up.

#3DPrinting folks, I am trying to see if I can run OctoPrint and make it work via a vertual serial port connection on my #Mac, here's the issue though, if I run #socat, I can't also then run #OctoPrint in the same terminal window because only the commands for that particular program work, is there a way to fix it so that I can run both Socat and OctoPrint at the same time?

Here's the situation for those who are interested, I have #OctoPrint for windows, I have been trying to connect it via #Moonraker as the bridge to my #Q1Pro which you might think would be easy, but it isn't. Why? Because, when I connect via my IP Address and port 7125, it resolves and I can load it just fine on my browser, but octoPrint can't connect to it, so #Moonraker works just fine and I have API access, but nope, fucking #OctoPrint just doesn't want to play ball and connect to it when I go in to the server settings. #3DPrinting literally any help would be appreciated, I just want to use my Printer accessibly as a #Blind person, but apparently that is too much to ask out of OctoPrint.

Man, I have been fighting with Moonraker, OctoPrint, and my printer for days. Its not easy to do, and while I can SSH in to my printer well enough, getting it set up so that I can use it with #OctoPrint is literally painful. #3DPrinting

I still wish I could get #OctoPrint to work with the #Q1Pro, but it doesn't seem like its going to happen any time soon which sucks because OctoPrint is way more accessible for the #Blind than #Fluidd.
