    Default Small Composite Router Build 1000 X 600 X 300

    I couldn't tell you why. Maybe I just like to do things the hard way, maybe I like the looks of things built with composites.

    Maybe, we'll see, if I'm just another dreamer.

    Tecnik 3437 Servo Motors Discontinued from a previous project. More on that in a future story.

    Instrument-grade motor, 400 oz-in, 4000 count/rev encoder and step and direction drivers.

    That pretty much sums up the main stuff.
    Still need to get wires to make harnesses, a power supply for the axis motors, and wire chains.

    The composite materials will be outlined in future post.

    This is my second CNC project. The first was a knee mill conversion, with many mistakes, and some really cool results. I had intended to make something a lot more ambitious, but my better angels prevailed. The next post will be the Fusion 360 designs images. I hope you guys have fun following along and I am looking forward to your incites, observations, and advice.

    Someplace on the net there is an example of a router / Bridge mill made out of composites. If nothing else it would offer some inspiration, unfortunately I don't have a link.

    1610 ballscrews are a much better choice, as are profile linear rails over round supported shafts.

    Thanks Gerry,

    I couldn't agree more. But this little machine is going to be used primarily for making wood signs. I am going to try cutting some aluminum as a test of accuracy under heavier loads.

    The immediate need is to make signs, The 600 X 400 Chinese Routers would solve it, capacity wise.

    I started to research them and found out they have lots of problems. So I stated looking for kits and components to keep my cost within this range. Worst case I will try adding distance to the blocks to minimize movement. As far as travel speed is concerned, The affordable kits I found all have 5 mm pitch. These motors are capable of 3000 plus rpm at 60 volts so that is 590 ipm. Not fast by industrial router standards, but the travel for this application is short.

    If this machine starts to make money then improvements will be much easier to justify.

    Please continue to give me opinions and advice. This is the first of several machines I have in mind.
