Tutorial, BOM and Fixture Bed

During last three weeks we have been working hard in the tutorial. We wrote some chapters and are still writing more. Now we are working on the software installation chapter and then we will begin with the calibration chapter. To write it, we disassembled the prototype and assembled again, and we seize the opportunity and we changed some old parts that were printed in different colours. Now it looks better. And it still works! :-) Every time we re-assemble it we find some tips to improve something. We published some of them in the tutorial.

On the other hand, our warehouse is now plenty of stock. We receive all the materials we needed and our 3D printing farm is also printing all the day.

We received some questions about the BOM of the Pickup Driver. We exported the BOM directly from Eagles CadSoft and in some devices it's not clear which package is needed. So we will clarify this in the following days.

We also received some emails asking why we do not sell the fixture bed and where it can be bought.

The fixture bed or platform is the piece of aluminium where we fix the PCB or material that we want to process. Really it is a complete fixing system composed of: a drilling stencil, the fixture platform and a small tube that attaches it to the Effector. It also has a screw to connect the spring cable. Optionally you can add a sacrifice plyboard for drilling and a glass to 3D print on it.

The fixture bed we have been using in the prototype was made by a friend using a manual milling machine. But to sell them at a reasonable price we need to find someone who manufactures it in series using a CNC milling machine.

Two weeks ago we contact a supplier and we are making some tests to check that the quality of the machining and the price is adequate. It is very important that it will be manufactured with precision: the holes of the platform and the stencil have to match perfectly and the dowel pins has to fit in the holes with minimal gaps.

Anyway, in case you want to make it by yourself or order it to a local milling company, we've updated the Autocad blue-prints to include detailed instructions about its construction.
