Little off-topic, but this is the first tests of my build of the Cyclone PCB Factory.

It is a small RepRap-like CNC milling machine intended for PCB manufacturing. Its goals are easy building, low-cost, as much 3D printed parts as possible for easy replacement at home, and an open design.

Where did you get that spindle from ? Also, how much backlash do those gears introduce? PCB end mills are quite sensitive to run out and backlash…

The Spindle is this one: http://cgi.ebay.es/ws/eBayISAPI.dll?ViewItem&item=191039459030

The backslash introduced by the gears depends on how well are they printed and how much do you “push” one to the other, because the motor mount has a little slide to adjust it. It’s a little handy but you can get close to zero backslash in this place.

There is another backslash problem due to the threaded rod - nut, 'cause a metal nut always has a little gap between it and the rod/screw. It can be avoided with two nuts and a spring between them for example.

Also, as you can see, I’m on my very first tests, I’m waiting for the engraving bits to arrive and then I’ll try with a real PCB. So I haven’t experienced real problems by myself for now.

nice taiwan spindle ! maybe i should try it one day … oh btw : what kind of blank PCB do you use? were you able to find NON-FR based blanks?
