Owen's Electronics Enclosure

Post by MathewOwen » Sun Mar 17, 2013 6:47 am

I decided to build an electronics enclosure for my recently acquired ShapeOko. The suggested curved acrylic plate was nice but not entirely practical. Besides, I enjoyed designing and building this enclosure so for anyone interested, here it is.

- 24v 5a power supply (eBay $15 incl. shipping)
- 24v 1.4w Papst Fan ($10 eBay)
- Power switch ($3.19 at Radio Shack)
- Power entry component ($0.60 local hardware store)
- e-Stop module ($5 for 2 - eBay)
- Arduino ($35 Radio Shack)
- GRBL Shield ($69 Synthesos.com)
- 4 x 4-pin connectors ($5 for pack of 4)
- M3 & M5 bolts ($5 local hardware store)
- USB cabe ($3)
- Power Cable ($1.49)
- 1/4" birch plywood - 24" x 12" - 3 pieces ($10 hardware store)
- Extra cables ($6 for 6 feet from inventables)

Total electronics with enclosure came out to be just about $160 (not bad at all - you will need patience for all components to arrive, many come from China or elsewhere and can take a long time). Very happy with my setup, I ordered a Buildlog.net stepper shield so will compare that soon (was much cheaper than GRBL!!).

e-stop button connected to the top. Working on integrating an external reset button as well.

Image
4-pin connectors (only using 3 at the moment but will install the second Y-axis motor soon).

Image
I used a raster to cut into the wood as it was too thick for the pins. Since this is my first CNC I used a laser cutter instead. If you use 4-pin connectors make sure the threaded part is long enough to fit through.

Image
Using a power switch and 3 prong power connector. Very cheap and easy set up (instead of a power entry module).

The top of the enclosure showing the e-stop button connected. Thinking about making the top from transparent acrylic.

Will post more images once it is completed along with files in case anyone else might want to build one too. Thanks for looking & feel free to ask any questions.

Hi Matthew,

This is a fantastic looking enclosure! I'm really looking forward to seeing these design files so I can build one myself.

I have to say, very clever thinking to raster the section where the 4 pin connectors are located! I've had that issue before, where the material is too thick to accomodate the thread length (or lack there of), and each time have either botched the job, or taken a hand router to it, and faking a pocket. Your enclosure looks so much cleaner than any of my attempts.

Where do you get nice connectors like that so inexpensively? Got a part number?

eBay, under the search for 'c146 connector'. They only come in 4pin variety that I can find, but they are inexpensive.

Thanks, I orderd them for my system.
The nice thing aboud those connectors are that the shroud can handle the grounding for the motors. Just peel the shield back over the cable and close the female connector. On the other side use a amp ring connector for connection to the male chassis connector.
Less EMI so the better the system will work. If you want to ad wifi, blue tooth or x- zigbee it's a must.

Nice enclosure you build. Butt ad a fuse to you 110/230V AC input for your own safety.

Hi Edward,

Thank you very much for the compliment! Its just a simple design though (mostly based on organizing everything without being too expensive or difficult to build). There are a couple things that need to be redesigned, so I will post the files very soon.

The rastering was a great success (I will admit I discovered this entirely accidentally while engraving the ShapeOko name) and is surprisingly easy to control once you experiment a little bit with the settings.

Really loving the shapeoko! Just got it to write its own name last night. Have to thank you for putting this together and sharing all this information. Truly amazing!

Nice enclosure you build. Butt ad a fuse to you 110/230V AC input for your own safety.
@ Rob, thank you for the advice. Any advice regarding electricity is very much appreciated.

This is indeed one of the best enclosures. Would you please post the design files?

Thanks

Yeah, that looks good.

But why not use XLR connectors instead of the c146 connector?

No fiddling about with the Earth as this has 5 pins.

There may be cheaper ones out there.

Alternatively, IP68 rated connectors:

Those are not XLR connectors. They're the same series as the C146, only the 5-pin variant. I have no idea what they're properly called, but they have nothing to do with XLR.

They are the connectors that are typically used for Ham and CB (Citizen's Band) radio microphones. They're available with a number of pin configurations from 2 to more than 7 pins. Can be found at any CB radio shop or by searching for "CB Microphone Connector" online.
