    Default David A's Benchtop CNC Version 2

    Hello all,

    Some of you might remember, I had posted a thread called "David A's New 2x3 Benchtop CNC" about two years ago.

    https://www.cnczone.com/forums/diy-c...h-top-cnc.html

    The machine has been running good and received quite a bit of changes in those two years so I thought I start a new thread showing the improvements I made since then.

    First, I built a double-walled base out of Birch ply with 4x4 posts at each corner. Bottoms of these
    pockets are closed in case I want to mass-load it with sand:

    It takes 2-1/2 sheets of 4x8 ply and about ten feet of 4x4 post.

    For anybody who might want to build something similar, each image is one sheet:

    I plan to build these machines in 2x2, 2x3 and 2x4 sizes and make them available for purchase.

    Therefore, I will progress with the thread like a customer had just received his/her order.

    The sample desktop shown here is the 2x3 desktop.

    The machine will arrive in a reusable birch ply crate:

    With panel markings for re-assembly:

    The crate is disassembled/reassembled with industry standard steel clamps:

    The crate contains the fully assembled, bolted, bonded and watertight machine frame.

    Thank you Hugues.

    The naked frame weighs about 170 lbs.:

    All mounting surfaces for linear rails on the machine are machined:

    All other assemblies of the machine are mounted on the bottom plate of the crate, underneath of the machine frame.

    I wanted to fill the base with sand as it would be difficult to access the pockets after the top and the machine is put on the base. Couldn't find any sand which was dry. All the bags were somewhat moist. So I filled the base with 400 pounds of moist sand.

    Letting the sand dry in the pockets before proceeding:
