The PCB prototypes can be easily made on CNC machine.
For this task I created a schematics in the OrCAD
(Cadence product for  PCB design),
and then transferred the layout to the DXF file.
For engraving process I used ROLAND EGX-350 CNC machine.
Due to I used a few ​through hole components, the PCB size was not limited,
so I choose it according the enclosures that I have in my stock.

<p>it's look good</p>
<p>what should be the torque rating and minimum step angle of stepper motor used??</p>
how 'bout some text?
<p>which text ?</p>
I don't think you know how this site works, look around and see how Instructables are set out.
<p>maybe you right... I'll check it out...</p>
We were all new at some point. Add some steps detailing the machine, the software, your purpose,your bill of materials. That sort of thing, it means others can then replicate what you have done.
<p>Ok, thanks for the tip !</p>
