    Thought I would share my almost finished MPCNC with you guys as a thank you.  I am a Marine Tech and wanted to be able to offer my customers custom dash panels, switch plates, etc. when doing new engine installations and upgrades.  I stumbled on the MPCNC during a quick search.  I have no background whatsoever in CAD or CNC, but I really enjoy making stuff!  After perusing the forum over here for a bit and seeing how helpful everyone was, I ended up comfortable with the idea of going for it and ordered my kit from Ryan.  The website was super helpful and all the instructions were clear enough for a noob like me.

    Bought an inexpensive 3d printer and figured out Cura.  3 weeks later and I have an operational CAD table.  I even taught myself to use Onshape and designed my first ever part, 3-d printed it and installed it on my new MPCNC.  (Milestone!)  It’s a mount for the center assembly drag chain that doesn’t attach to the z axis (Because Ryan seems so against it!).

    I’ve been getting the machine dirty and slowly learning the ins-and-outs of Estlcam.

    The build is 2×3 (though I really wanted 2×4 so that I could fit full widths and make some furniture.  Guess I’ll just have to start printing the parts for a lowrider…).  .065 stainless tubing (which i bought enough of from my local supplier FOR the lowrider as well….) with a chinese 500w spindle.

    Just need to create some kind of enclosure to mount the rambo board, spinle speed controller, stop switch and power distribution in (open to suggestions!)

    I would love to hear your thoughts on the build – including constructive criticism!  Thanks for the quick responses on the few questions I’ve had.  I enjoyed the heck out of this build!

    I had a slight issue with my center assembly being out of square no matter what I tried.  Luckily I had ordered the dual end stop kit.  The dual end stops were super easy to set up and with the firmware already flashed by Ryan it was basically plug and play.  I can now draw a 2’x3′ square that is under 1/32″ out of square

    Haha Ryan you dont have to lie, I think we all know how you feel about cable chain.  Looks great just be aware of the drag chain catching oversized parts sticking out the back.

    Any chance you want to share that z axis chain mount?

    Looks like a great setup! Which spindle are you using?

    It is a cheapo 500w import spindle.  I’m not sold on it yet.  I seem to be getting quite a lot of chatter especially in plywood regardless of my feeds/speeds.  Thinking that the low rpm (12500 max) and long collet adapter are contributing to the problem. I’m still trying to figure it out, but it might just be my lack of experience!

    It’s super quiet….until it starts cutting.  The little fan on top is held on with some loose snap rings top and bottom that make a bit of a racket also…just dropped a little super glue on them and they quieted right down

    I have a DeWalt 660 due to be delivered tomorrow that I want to try out.  We will see if it makes a difference

    Finally had enough of listening to the dw660 scream in my garage, and the sodust that went with it.  I built a quick enclosure.  Figured I might as well share it!  Now I can work in there while it’s. Running without ear protection!

    Nice, I need to enclose mine just for some dust control! You guys keep making these and giving me a lot of motivation!
