CNC / 3D Printer alternative?

Hello all,
A dream of mine is to one day design and build a hexapod from scratch (isn't it everyone's?) from acrylic/MDF/similar.

Hey folks, Here is one I did just for fun. Yup, its a whole X/Y plotter and yup, its in a box! Woo Hoo! Its a pretty simple setup, the Y axis is via a 2" aluminum … Read more

DIY CNC Safety Guide + Emergency Stop Button giveaway

Hi guys, 

Recently I've been worked with RS Components to make a safety guide for the DIY community, mainly focusing on DIY CNC machines. I thought it might interest you because some of you use CNC machines for building your robots. 

Also, get in touch if you feel that some of your machines could use a shiny big red emergency stop button, I might be able to send you one!

The main aim of the project is to raise awarness about safety issues, so feel free to share any of your own experiences and tips!

 

Cnc or 3D printer?

So, this is my problem: Which one should i buy? Tell me pros and cons, like price and complexity. Some of you have knowledgement with these things, and these guys know a lot of these things. But most importan thing: I need something affordable and it can be used to produce robot parts Thanks, BotFIN

PCB CNC Drill

So this is the basic idea, more so I don't forget but any input/comments always welcome.

Create a mini CNC for drilling PCB's, it would require...

Building an X/Y Table similar to Geir's (sorry can't link, using a Tab). Instead of a pump hook up a 12v motor with a drill bit adapter

Mount the motor so it can move on the Z axis, either on a spring with a servo to push it down, or threaded rod like normal CNC mechanics. Use the handy TIP120 for switching on/off. (2.2K resistor, Diode)

CNC control from a laptop

I've put this in ideas cos I'm not sure where it fits, but the project itself is still in the ideas phase so i think it's ok :D

Basically I'm slowly assembling parts and designs for a CNC milling machine, the usual xyz stepper motors with router on top sort of thing.

What I'd like to know is if it's possible to control it from a USB-parallel converter, I've read some things about the interpreting speed not being up to it (All I have at the moment is a laptop, so no parallel port)

Hackerspace and other things

I have been away for a while again :(.  But right now I am sitting at my desk sick as a dog.  I felt I should take this time to update my LMR.  I haven't been able to post my current projects on this site because of this.  Saskatoon TechWorks, a new hackerspace community that has been established.  This means that I will be able to share my knowledge and tools with other like minded individuals.  As an added bonus, I get to use awesome tools as well.

Alright - this is beautiful - All you CNC people will like this....

Near Sci-Fi like in that you could imagine hundreds of them automated... cranking out parts, possibly replicating as a new life form on the Sahara :)   Theo Jansen would approve...

PCB CNC Mill: Clamping makes a difference

This might be useful to anyone else here with a DIY CNC who does PCB milling: http://blog.holyscraphotsprings.com/2011/05/good-circuit-boards-require-good.html

I've had a really tough time figuring out how to clamp my PCBs: my boards often look like the "bad PCB" here: http://www.flickr.com/photos/11461247@N02/5697373918/

CNC electronics

I'm in the process of building a CNC machine right now and would like a little help from the experience ones.  Right now I have $250 saved up and counting.  I'm trying to figure out what to do about stepper motors, power supply, and motor controller.  I didn't know if it be best to just buy a package that have it all in one and what would you recommend.

CNC Machine V2 with RepRap Controller

I finally finished my Fireball V90 CNC build.  In May, I got the frame, and I planned to use the motors and electronics I purchased for upgrading the Valkyrie-clone CNC.  So I made some NEMA-17 to NEMA-23 adapter plates from CD-R disks, and got it all up and running.  It's running off 12V for now, with 24V planned in the future.

 

This is a secondary documentation page for my Senior Project for highschool, I'm building a cnc router with a budget of $700 bucks. Basically, the plan is to build … Read more

Rout-X, my CNC router

Long time ago, about 5 years I think, I started looking up DIY CNC machines. I bought the 4 axis EZ Driver combo kit from Hobby CNC, together with the CNC plan they had at the time. But I didn't had time to order the acme screws and linear bearings and I left USA and returned to Romania. Over there, I had an attempt after this site, but it didn't came out good as I did some mistakes.

For now its almost done! My selfbulid CNC-Mill is ready to use. It all started during my x-mas holidays when I found Tinheads Valkyrie here on LMR. I had the idea … Read more

RepRap Stepper Driver v1.2 and Next Gen CNC

In the picture from top-left, clockwise to bottom-left: the terminal block (24V power up to 13A), the 2 X-axis drivers, the Y-axis driver (blue heat sink), and the Z-axis driver (blue heat sink), the Arduino controller (direction x3/enable x3/step x3), and just below the terminal block there is a small 9V regulator board to shift 24V down to 9V for the Arduino.  Everything is mounted on an MDF board, and the board is mounted with baling wire.

RepRap Conversion for a set of Probotix SideStep Stepper Motor Drivers

Abstract

An Arduino or similar microcontroller shall be used to create a RepRap-style front-end for the HobbyCNC EZ Driver board or similar DB-25 controlled stepper driver.  This front-end microcontroller application would allow RepRap applications to control a number of powerful CNC machines.

Introduction
