    Looking good man! I dig the color scheme! Looks like you were careful to buy some excellent components. Once you have your cnc working, you will most likely start dreaming up another bigger cnc. Most of that hardware will be transferable. How did you seal the MDF before you painted it?

    Keep going!

    I didnt seal it. Someone told me I should have applied wood hardener on it first but it was too late. Do you think I will have issues?

    The quality of the finish made me think you sealed it. I can't imagine there will be any issues from not sealing it before painting-just harder to get a good finish. When I sealed my MDF with Polyurethane, I was shocked at how rigid the MDF got.

    Looks good - what is the footprint of the unit and are you following someones plans or is this your own design?

    My cutting area will be roughly 12x36. I am not following any plans just getting inspiration and ideas from Google Image searching. I really have no clue what I am doing

    Nice build! What CAD/CAM software are you going to use? MACH3? EMC? What are you planning on cutting first? Cheers!

    I am going to try LinuxCNC(EMC2) for starters. I have no idea what I am going to cut first. Its my first build so I am still hoping the thing is just going to work.

    I recommend EMC2, it's what we use and it is amazing. I got on a shopbot and the interface was so clunky compared to EMC, I just could not stand it.

    Another slow few days but I got the end connectors on the motor leads and the wire chain on the z axis.

    That's one of the best jobs I've seen on an MDF CNC! Awesome work!

    cheers,
    Ian

    It's a state of mind!

    I made some progress finally! Got all the electronics hooked up and did a motor test. Everything seemed to work just fine as far as I could tell. I uncoupled all my motor connections for the test but I did get my Y axis all connected back together and moving before I ran out of time

    Just a thought,

    In this photo I can see that the router collet can go over the steel guide rail. I recommend moving the guide rails under the table top so that the full width of the table top can be used for cutting. This would lower the Z axis by the amount of the table top thickness and will cause the lead screw to be relocated downward by the same amount. You may not want to do that now that the machine is built.

    A simpler way to do the equivalent is to add a spoil board layer on top of the table and notch it to fit over the rail and bolt heads as far as the bearing carriages will allow. That will give a little more cutting width on each side. Just don't accidentally drill through the rails due to errant gcode or failure to re-zero the cutter after a tool change.
