    Just found this for another member and thought I would share it with everyone else:

    I think generally any of the 30xx machines are ok to use as a learning platform, if users keep things real in terms of what they should expect from these machines it can be a win win situation.

    Engraving copper shouldn't be a problem as its quite a light task to do, for engraving from what I've seen, spindle speed set at around the 10,000rpm mark seems to work well.

    Have you seen this offer, there is 50% off at the moment, free shipping and at only 125 it seems ridiculously cheap not to get one to play around with !

    Would you think that a machine like this would be accurate enough to mark-out the centres of where holes are to be drilled in making Gantry side-plates?

    Sorry but it's like buying a kite to learn basics of flying.

    You need a proper mini mill at least to learn basics of machining. I wouldn't spend a single $ on a stuff like that. Also if you want a laser, buy a laser. All you say is a recipe for wasting money.

    I think it's worth noting that they say:
    "Engrave Wood, Plastic, Acrylic, PCB, or Similar Material
    Can Not Engrave Metal, Steel, Aluminum."
    So they're honest about its capability, or lack of it.

    These things will engrave metal including stainless you just have to go at it slowly. From my research there is a huge variety of CNC3018-Pro machines out there with differing control boards being the difference.
    Some have later driver chips on with a finer resolution, some appear tohave the row of pins A1 etc on the bottom disabled which is not helpful if you want to use a Z axis mapping function.
    For that reason I shall probably be buying the Sainsmart one which although a little more expensive has the latest iterations of components and supposedly reasonable customer support.

    I bought one of these machines about a year ago because for years I've had alsorts of ideas about building my own design router but didn't get anywhere past dreaming as I have little electronic knowledge. It is a great training tool, it's modular so it's cutting areas can be tailored to what you want within reason by buying longer extrusions and screws.
    I only use it for light work such as cutting depron and balsa wood.

    I now feel confident enough to start building a much more substantial moving gantry router.

    I rigged up a brushless spindle for the router, photo attached. This was made to fit in the original mount. Mk2 will have pillow blocks rather than the flanged bearings of Mk1.
    A torque arm stops the motor from spinning.Click image for larger version.
