New DIY CNC Micromill

Hello all,

Thanks to "caudlet" for uploading a photograph of my new machine, it
is in a folder named "Salvador's Micro Mill", in the Photos section.

Still some small details must be done, like bellows in the Z axis or
to attach the springs that I've put to cover the soldered wires of the
motors, for cosmetic reasons. I'm still thinking how to do the last
task in an elegant way.

I think that I like more to design and build machines that to make
jewellery.

Though it's a machine with ballscrews and linear wagons, it's a basic
machine, no limit switches or similar yet. The purpose of the machine
is to make engravings in jewellery pieces. The drivers are bipolar
ones with 1-64 microsteps. I have tested two linear axis and the 4th
one, while doing the machine, but with 1 to 8 microsteps drivers. All
Ok, but I must build now the final driver box.

At the begining I was taking photographs of the diferent pieces and
intermediate assembly process, and they are in a PowerPoint file. When
The X, Y and A axis where ended, I forgot to take more photographs. I
don't know if some of you are interested. The file weights 1'03 Mb,
but as the uploading is limited by the moderators I could send the
file to anybody who wants it, or could upload the individual files to
an image server.

The machine was done with a CNC'ed 103 kg milling machine, the Optimum
BF20 Vario that whe know very well here in Europe. Very few lathe
work. I used TCNC. It has been machined with a precision of 0'01 mm,
or better, where it has been a must.

My best wishes to all.
