3D Printers Get a Fuel Gauge: Adding a Filament Scale to OctoPrint

Posted on by

It seems a simple enough concept: as a 3D printer consumes filament, the spool becomes lighter. If you weighed an empty spool, and subtracted that from the weight of the in-use spool, you’d know how much filament you had left. Despite being an easy way to get a “fuel gauge” on a desktop 3D printer, it isn’t something we often see on DIY machines, much less consumer hardware. But with this slick hack from [Victor Noordhoek] as inspiration, it might become a bit more common.

He’s designed a simple filament holder which mounts on top of an HX711 load cell, …read more

Coolest Way to Watch 3D Printing: Lights, Camera, Octolapse!

Posted on by

Octoprint is a household name for anyone into 3D printing and anyone regularly reading Hackaday. Described by creator Gina Häußge as “the snappy web interface for your 3D printer”, Octoprint allows you to control effectively any desktop 3D printer over the local network or Internet. It even has webcam support so you can watch your printer while it works, meaning you can finally put that video baby monitor back into the crib with Junior.

While the core functionality of Octoprint is fantastic alone, its true power is unlocked through the plugin system and the community that’s sprung up around it. …read more

3D Printering: Which Raspberry Pi is Best at Slicing in Octoprint?

Posted on by

OctoPrint is arguably the ultimate tool for remote 3D printer control and monitoring. Whether you simply want a way to send G-Code to your printer without it being physically connected to your computer or you want to be able to monitor a print from your phone while at work, OctoPrint is what you’re looking for. The core software itself is fantastic, and the community that has sprung up around the development of OctoPrint plugins has done an incredible job expanding the basic functionality into some very impressive new territory.

But all that is on the software side; you still need …read more

3D Printer Time Lapse Videos Ditch the Blur

Posted on by

Most time-lapse videos of 3D prints show a steadily growing print with a crazy blur of machine movement everywhere else. This is because an image is captured at a regular time interval, regardless of what’s physically going on with the machine. But what if images were captured at consistent machine positions instead? [FormerLurker]’s Octolapse plugin for OctoPrint came out of beta recently and does exactly that, and the results are striking. Because OctoPrint knows where a 3D printer’s print head is at all times, it’s possible for a plugin to use this information to create time-lapse videos where the print …read more

Controlling OctoPrint on the Go

Posted on by

Not too long ago I took the plunge into the world of OctoPrint by shoehorning a Raspberry Pi Zero into a PrintrBot Play, and I have to say, the results were quite impressive. OctoPrint allows you to run your 3D printer untethered from your computer, but without all the downsides of printing off of an SD card. Generally running off of a Raspberry Pi, OctoPrint serves up a very capable web interface that gives you full control over slicing and printing from essentially any device with a modern browser.

That’s all well and good if you’ve got your laptop with …read more

Upgrading a 3D Printer with OctoPrint

Posted on by

If you’ve been hanging around 3D printing communities, or reading the various 3D printing posts that have popped up here on Hackaday, you’ve almost certainly heard of OctoPrint. Created and maintained by Gina Häußge, OctoPrint allows you to turn an old computer (or more commonly a small ARM board like the Raspberry Pi or BeagleBone) into a network-accessible control panel for your 3D printer. Thanks to a thriving collection of community developed plugins, it can even control other hardware such as lights, enclosure heaters, smart plugs, or anything else you can think to hook onto the GPIO pins of your …read more

Hackaday Prize Entry: A 3D Printer Management System

Posted on by

Since the first desktop 3D printers, people have been trying to figure out a way to manage desktop 3D printers and turn them into tiny little automated factories. One of the first efforts was a conveyor belt build plate that was successfully used by MakerBot until it wasn’t anymore. Octoprint has been a boon for anyone who wants to manage a few printers, but that’s only half the solution.

For his Hackaday Prize entry, [Mike] has come up with a solution that turns a desktop 3D printer into a completely automated factory. Not only does this project take care of …read more

Build A 3D Printer Workhorse, Not an Amazing Disappointment Machine

Posted on by

3D printers have become incredibly cheap, you can get a fully workable unit for $200 – even without throwing your money down a crowdfunded abyss. Looking at the folks who still buy kits or even build their own 3D printer from scratch, investing far more than those $200 and so many hours of work into a machine you can buy for cheap, the question “Why the heck would you do that?” may justifiably arise.

The answer is simple: DIY 3D printers done right are rugged workhorses. They work every single time, they never break, and even if: they are an …read more

Hackaday Links: April 17, 2016

There have been really cool happenings in the CNC world for the past few years. There is a recent trend of portable, handheld CNC machines. Yes, you read that correctly. This SIGGRAPH paper demonstrated a handheld router with a camera and a few motors that would make slight corrections to the position of the router. Load in a .DXF or other vector file, and you become the largest CNC machine on the planet. We saw it at one of the Maker Faires, and about a year ago the team soft launched. Apparently, the Shaper router is gearing up for production …read more
