How To Make Your Own Springs For Extruded Rail T-Nuts

January 30, 2019 by 24 Comments

Open-Source Extruded Profile systems are a mature breed these days. With Openbuilds, Makerslide, and Openbeam, we’ve got plenty of systems to choose from; and Amazon and Alibaba are coming in strong with lots of generic interchangeable parts. These open-source framing systems have borrowed tricks from some decades-old industry players like Rexroth and 80/20. But from all they’ve gleaned, there’s still one trick they haven’t snagged yet: affordable springloaded T-nuts.

I’ve discussed a few tricks when working with these systems before, and Roger Cheng came up with a 3D printed technique for working with T-nuts. But today I’ll take another step and show you how to make our own springs for VSlot rail nuts.

Building A Bigger Shapeoko Router

September 17, 2012 by 15 Comments

Hackaday alumni [Will O’Brien] sent in a few projects he’s been working on lately while he’s in the process of upgrading his workspace. He’s building a 1200 x 1200 mm CNC router based on the Shapeoko router, and it sure looks like he’s having fun doing it.

The Shapeoko router is based on the Makerslide open source linear bearing system. This system uses common aluminum extrusions as the frame of a very simple, very inexpensive CNC router. The Makerslide system is designed to be expandable; if you want a larger axis, just bolt in a longer piece of aluminum extrusion. We haven’t seen many Makerslide builds take advantage of this fact, a shame as the stock Shapeoko only has a build area of 200 mm square.

[Will] is expanding this build area to 1200 mm square, but of course this means beefing up some parts of the build. He’s already moved up to very hefty 250 oz/in Nema 23 stepper motors (up from the Nema 17s for a standard Shapeoko), as well as beefing up the motor mount a great deal.

[Will] also sourced a few lengths of cable drag chain (yes, that’s what it’s called) to keep all the wires for his huge CNC routers out of the path of a moving gantry and spinning motors. It looks like he’s got a very nice build shaping up, and we can’t wait to see it in action.

MakerSlide, European edition

We’re all familiar with the MakerSlide, right? The linear bearing system that has been turned into everything from motorized camera mounts to 3D printers is apparently very hard to source in Europe. A few folks from the ShapeOko forum have teamed up to produce the MakerSlide in the UK. They’re running a crowdsourced project on Ulule, and the prices for the rewards seem very reasonable; €65/£73 for enough extrusion, v-wheels, and spacers to make an awesome CNC router.

Kerf bending and math

A few days ago, I made an offhand remark asking for an engineering analysis of kerf bending. [Patrick Fenner] of the Liverpool hackerspace DoES already had a blog post covering this, and goes over the theory, equations, and practical examples of bending acrylic with a laser cutter. Thanks for finding this [Adrian].

276 hours well spent

[Dave Langkamp] got his hands on a Makerbot Replicator, one thing led to another, and now he has a 1/6 scale model electric car made nearly entirely out of 3D printed parts. No, the batteries don’t hold a charge, and the motor doesn’t have any metal in it, but we’ve got to admire the dedication that went in to this project.

It was thiiiiiiis big

If you’ve ever tried to demonstrate the size of an object with a photograph, you’ve probably placed a coin of other standard object in the frame. Here’s something a little more useful created by [Phil]. His International Object Sizing Tool is the size of a credit card, has inch and cm markings, as well as pictures of a US quarter, a British pound coin, and a one Euro coin. If you want to print one-off for yourself, here’s the PDF.

Want some documentation on your TV tuner SDR?

The full documentation for the E4000/RTL2832U chipset found in those USB TV tuner dongles is up on reddit. Even though these chips are now out of production (if you haven’t bought a proper tuner dongle yet, you might want to…), maybe a someone looking to replicate this really cool device will find it useful.

Three days of work in 5 minutes

[Celso] bought himself a Ultimaker kit and put together a time-lapse video of him putting it together. There’s a lot of work that goes into these machines, but being able to print a nearly perfect cube on the first run is nearly magical.

How about a CNC mill, too?

The folks over at Inventables have put together a tiny CNC mill kit designed from the fruitful mind of [Edward Ford]. The Shapeoko mill is designed around the Makerslide linear bearing system, so you’re getting a lot of precision very easily. Here’s some more info on the Shapeoko

Update the firmware on your RasPi

[Hexxeh] has been playing around with the Linux images for his Raspberry Pi, so he needs to reinstall the firmware on an image quite a lot. He wrote a tool to automate this task, but it should be useful for RasPi users that want to keep kernel and firmware up to date. You can get the rpi-updater at [Hexxeh]’s GitHub.

Your robotic barista is still always on the phone

Zipwhip is a company that provides a bridge from your phone to your computer so text messages can be displayed on your desktop. To show off their tech, they created a text enabled espresso machine. Everything on this robotic barista is automatic: the cups are grabbed from a warming tray with a servo arm, coffee is automatically brewed, and the last three digits of your cell phone number are printed on the foam to identify each cuppa. Check out the video; action starts at 1:30.

Awesome reading material

If you’re looking for something to read on that fancy tablet computer of yours, here’s every issue of New Scientist from 1956 to 1985. The early 60s issues say fusion power plants are about 50 years away, so we should be just fine in a couple of years.

Yet Another 3D Printer

February 8, 2012 by 24 Comments

What would you do if you wanted to demonstrate a linear bearing system? If you’re like [Bart] the obvious solution is building a tiny little 3D printer. [Bart]’s Quantum ORD Bot is constructed out of a previous project of his, the MakerSlide linear bearing system.

The idea of a printer made out of MakerSlide materials came from [Bart]’s invitation to ORD Camp. The fact that this build went together in about 5 hours speaks volumes about the simplicity of the MakerSlide system. Right now, the printer is designed for NEMA 14 motors, but for larger builds there’s plenty of room for the larger NEMA 17 stepper motors. [Bart] put up a build log for his printer up on the buildlog.net forums.

The MakerSlide system has already been used in an open source laser cutter project, but [Bart] really just wanted something to demonstrate his linear bearing system. We like the bot anyway; not enough stuff is made out of aluminum extrusion these days.

[Bart] is going to be showing off his bot at the Chicago hackerspace Pumping Station: One tonight, February 8th. Stop by and check it out. Snap a few pictures for us and we’ll put them up.

EDIT: [gigawatts121] was kind enough to send in a picture of the printer at Pumping Station: One. There’s also a video of a calibration cube being printed courtesy of [David] in the comments. Check that out after the break.

Open Source Linear Bearing System

May 10, 2011 by 53 Comments

makerslide

While we normally don’t make it a habit to feature Kickstarter projects, we couldn’t pass this one up. [Barton Dring] from BuildLog.net is putting together a project called MakerSlide that we’re sure will interest many of you out there.

Through his various CNC builds, he has found that one of the more expensive and frustrating components to obtain is a linear bearing system. He notes that commercial systems are expensive, and while an occasional eBay bargain can be found, it’s not the ideal way of going about things. He also points out that homebrew systems usually work after some tuning and adjustments, but can be time consuming to build.

He is proposing a v-groove bearing system, complete with wheels made from Delrin, as a standardized replacement for all of the aforementioned solutions. He anticipates selling the rails for about 10 cents per centimeter, putting the average cost of a 4 foot system around $20.

As a bonus, he is offering up free MakerSlide materials to anyone that sends him a “new, innovative  or interesting open source design or basic idea that uses the material.” You would only have to pay shipping in order to get your new project off the ground.

Standardization is always good, and seeing this rail system go into production would definitely benefit the hacker community. Take a minute to check it out if you are so inclined.
