Ruwan's Build

[janapriya]

First of all Thank You Edward for this wonderful project. Also I would like to thank everyone who answered the questions I had during my build.

I've bought the mechanical kit and bought electronics separately. I went ahead with Nema 23 motors since I wanted to extend the machine in the future. Originally planned 1m Y axis, even assembled that once, but later I've decided to stay with 500mm Y axis until I really need that. Following document contains all the items I bought during this build. I'm not proud of the amount I spent on shipping. For example, Instead of ordering all at once, I've had multiple orders from inventables, shop.shapeoko.com hence paid for shipping for each order. I followed Caleb's build for electronics, but at the end I used Build.net shield instead of C10 board.

I hope someone could benefit from the following document.

This is my build video.


Once I built it I realized my bed is not flat and some issues with squaring. So I spent some time on squaring the machine. I will explain it in detail in the next post.

My 4yr old son is also interested in a Shapeoko build, hence I helped him to make following.

Awesome job, I love the build video. How long did it take you to put together?

Thanks Chase. I think it is roughly 10 or more hours. But I will confirm. Please note this is excluding the time I spent on Squaring the machine .

That's some very neat printing. The design is nice too, but it's the quality of the prints that stands out to me.

Thanks Catalin!
They came out great, except for one mount. Somehow Cura didn't like to print the holes for screws for that one. Slick3r helped me to get better results for other mounts. I'm still learning/calibrating my machine (Rigidbot).

Poor man's work holding mechanism

1. I have added 36, 1/4"-20 T-Nuts to the waste board. First I've marked the locations and then I drilled them. I've used a screw to tighten T-Nuts (screw is used to pull each T-Nut).
bought from http://www.amazon.com/gp/product/B0002ZPEMC

2. I've bought some 4in X 5/8in Mending Braces from ACE hardware: http://www.acehardware.com/product/inde ... d=29675496. Also I've used some 1/4" screws to build the work holding mechanism.

Ingenious! Upload to the wiki?

The reason many people prefer wood or plastic hold-downs is that, sooner or later, you'll run the cutter into one. Now that you can hold down material, mill yourself some hold-downs out of plywood.
