DAGU CNC mill controller - first prototype

I've been developing a CNC controller for DAGU. The project originally started late 2012 but got shelved because of other projects. Now we've dusted it off and plan to finish it in the next 6 months. Unfortunately blog post don't support video so watch the video that explains the basics by clicking on the link.

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!

Driving a CNC machine directly from an STL file with a DAGU Spider controller

I want to drive a CNC milling machine using only an Arduino processor and an STL file. The STL format was chosen because it is very simple for me to understand and almost all 3D CAD software can export an STL file.

In my forum post here: http://letsmakerobots.com/node/34958 the feedback I go was basically.

Converting an STL file to Gcode to drive a CNC mill or lathe

As mentioned in my blog, "Multipurpose Mini Machine" DAGU wants to develop a low cost CNC machine kit. The models shown here will not be the final product, they are simply what I used for testing the quality of the components.

Part of the kit will be an Arduino compatible controller. Ok, I know, nothing new so far.

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.

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.

Fireball v90 CNC using the PBX-USB board, and CNC-USB software

I've got a FireBall v90 CNC router kit, and a replacement PBX-USB controller board (that is based off of the CNC USB controlled board from plant-cnc.com) to go with it. I'm using the CNC-USB software to run it everything. I was wonder if anyone has experience with this kind of setup?

Phoenix Rising

Hi all!

A new year, a new reboot.

Valkyrie is officially dead, buried, gone ... RIP Valkyrie. 

She did her job, teaching me a lot of stuff about mechanics, electronics, programming and building stuff in general. 

Probably the most important thing I learned is to take your time doing stuff, because finishing fast does not always mean you finished good, sometimes you end up with a really crappy part and all work was in vane. Starting with  2011 I'll take the time to do it right, no mater how long it takes, if the end result counts.  

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.

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
