Hello Shofi,

Next week I'll upload the BOM and I might release the first version of the build-manual as well. All parts are sold from OpenBuilds, less the Arduino with CNC-Shield, junction-box housing and wood. Where are you from? I ask this so I can try to help you with the parts that are not sold at OpenBuilds.

Right, added BoM (Part list) and SketchUp V8 drawing to the project. Still working on the build-manual...

Thank you Mark.

I thought that a low cost router would have been more popular , people must be waiting to the build manual.

Hello Luca,

It can be used for PCB milling, the machine itself has the precision for it. However, you need to mount the Dremel or a precision rotary tool well and eliminate the play on the head as much as possible. Lowering the gantry helps with precision as well.

Hello webitman,

Thank you, it can still be improved a little. The manual is available now, it was uploaded a few hours before you posted but I forgot to write a line in the forum .

I've made another design based on this one but with a larger bed which is easier to mount/change. Some things I'll be adding to this build but first I need to to work on some other projects.

Thank you BNiner,

I forgot to add the flexible coupling I made in the file that was uploaded, on the next drawing I'll include it. You can find the coupling here (scaled up by 10:1 I think so you need to scale it down after you change the hole size) http://www.openbuilds.com/threads/better-5mm-5mm-flexible-coupling-drill-the-hole-you-need.1805/ .

Now, what would be nice is some feedback on the build manual .

Hello Erik,

Your welcome, took me some time to get the manual polished. There is a price difference of 120USD when you add the stepper motors to the C-beam Machine. The C-Beam machine is much better to cut Aluminum, the Routy is perfect for people that want to start with CNC with a Dremel or rotary tool mounted to it. So, I would recommend the C-Beam machine for sturdiness, but both can work with the same precision. With the price difference in mind, you can have a complete, ready to work, Routy for those 565USD, including the electronics (arduino+shield) and Dremel 3000 tool. The C-Beam machine needs a Dewalt or Bosch router that go for around 120USD, electronics can be the same; this will place a full build C-Beam machine at 755USD, 190USD more than the Routy.

Still, go with the C-beam machine for cutting harder materials .

Hello Eric, thank you, will change this directly as for sure it needs to be GT2!

Hello jkalberer41,

Did you get the SketchUp drawing of the 310 model in the 300 model topic? That one has a larger and sturdier table. I don't see any problem with adding more length to the X and Y axis, howebver, if you like NEMA23 motors I would take a look at the OpenBuilds Ox. Plates for the Ox can be bought from eBay (I get mine from Chris) and there are a few on the forum that also sell them. But, if this is your first CNC, the NEMA17 motors with a 14t pulley do a great job. Any tabletop CNC you will get, you will be upgrading sooner or later any way . I've thought about changing the X and Z axis to C-Beam. While it's a nice upgrade, it also adds to the cost and that's not what I wanted with this design. To be honest, I like the belt systems for small CNC routers, well, not that small as I also use them for 4*4' tables, but Acme is great as well up to 2.5*2.5'... Hard to say if it's worth it, the upgrade of the X-axis (gantry) to Acme...

-Ronald

 

No problem, you are welcome, I just wrote you back a PM to give you some extra ordering service. We're still working on a release of a kit.

Forgot to read the other post:

- Go with the 24vDC PSU, motors power up faster.
- No need for upgrading from the beginning, improve the parts that are not up to your spec later. I've thought about how to make this router better but it all involves a much higher cost at almost no advantage. (sure we want to sell more parts, but customer satisfaction comes first! )

-Ronald

 

Hello Eric, Since this is a low cost build I would stay with an Arduino and GRBL shield, using the DRV8825 drivers; from there you can upgrade later. You can also go with the Smootieboard directly; Smootieboard is much better then TinyG to say it simple. Get the 24vDC MeanWell powersupply from OpenBuilds, best on the market for it's price.

Hello Rob, this is an "easy" build after you have cut the the OpenBuilds V-Slot square and to the right size. Cutting V-Slot can be a challenge if you don't have a fancy miter box, table saw or better . You also need to tab some holes to M5.

The build instructions should be easy to follow, don't forget to download the manual first! And when you build and have questions, POST your build, share what you did and so others will share back to you!

-Ronald

 

Hello hernejj,

The Routy isn't made for "heavy" tools like that, you might take a look at the OpenBuilds Ox. I'm also working on a kit with stock OpenBuilds parts that will work with a 2.25HP router (released in a few months, so not that soon.
