      This is going to be a slow build as I am needing to spread my costs out over time, but I look forward to the process.

      Unboxing the frame parts.

      Frame assembled.

      The frame seems very rigid, although I apparently miscounted the number of cast corners that I needed for the frame as I was 8 short, but I've got those parts on my next order. I've ordered the rest of the bit (minus steppers) for the Y axis. I look forward to receive the parts and getting that much closer to a completed machine.

      Y axis parts received.

      And Y axis assembled.

      And attached to the main frame.

      Now I can't wait to get my X and Z axis to get the rest of the mechanicals taken care of.

      Woo hoo, more parts :)

      Lets start with the C-Beam Gantry Plate.

      And then the V-Slot gantry plate.

      And then to join the Z and X axis.

      Now I just need to get my C-Beam end mounts and then I'll be able to wrap up the mechanicals.

      Woo Hoo End Plates!!!

      Still gathering all of the electronics I'll need, here is a sample. Raspberry Pi 3, Protoneer CNC Hat, Power Switch, E-Stop, Panel Mounts for the Pi (Ethernet, 2xUSB, HDMI)

      Power Supplies (48V, 36-48V IN to 12V Out, 12V IN to 5V Out)

      I'm eagerly awaiting some other misc items, (power inlet, momentary switches). But I'll be ready to order drivers and steppers soon.

      More parts :)

      Here is the start of the enclosure I'll be using. That wooden box started life as an old tube tester, I thought I would re-purpose it.

      Test fit of some of the parts.

      Painted.

      Next step will be to start wiring. Once the power supplies, raspberry pi, buttons and connectors are installed I will be ordering my drivers and steppers. Starting to get close. I will be starting on the machine enclosure soon as well.

      Started wiring.

      More wiring.
      Tinned ends.

      Cables for all axes.

      Test fitment.

      Now on to the output cables.

      It's been a while since my last update, I decided against using the 6-pin DIN connectors as I was having problem soldering the 6 conductor shield cable to the 6-pin DIN. I think 18 AWG wires were just a bit too much to try and fit in there. Or I need to keep brushing up on my soldering skills. I ended up switching to molex connectors instead. This was much easier to work with. It does mean that I will eventually move to an entirely new enclosure not only to better mount the molex connectors but to achieve a better layout that won't be such a rats nest of wiring.

      Speaking of the rats nest here is the current state (I believe I can still tidy this up a bit, but not as much as I would like.

      Also here is a test g-code file running.

    Reason for this Build

    I have long wanted to build a CNC machine, I always have different ideas of things I could make or design but have always lacked the means to make them. With the building of this machine I look forward to being able to turn my ideas in to real physical things.
