The Precision Build

I will call this machine “Precision”. This is my first build of a CNC and this build has a working area of 305x305mm. I printed the parts on a Bambu Labs X1C with 0.16mm layer height for all parts.

I used the PLA Glitz grey filament from add:north and PLA+ from eSun in the color gold.

For the spoilboard, having little experience with clamping and workholding I drilled a lot of holes in a MFT pattern with 20mm holes in a 96mm distance. I am not sure if this is a good approach.

I intend to use a Makita router for this build.

I have all the printed parts, I have all the hardware and what remains is to cut the z-axis pipes, drill the holes in the z-axis and start to assemble the cnc.

I am not sure on where to put cable chains, I need atleast 3 cable chains? And is it a good approach to use the rails for motor and end-stops cables?

Also, for the LR3 Jackpot CNC controller case, what size scews are recommended? And is there a preferred rotation of the Jackpot?

And is a SD card in the Jackpot needed?

That’s a beautiful machine, such a good color scheme makes me wish I would have been more cohesive with my colors.

Wow, impressive work!!

A few replies, while waiting for the MPCNC builders to weigh in.
Great build so far.

I used M3s to mount my Jackpots to my enclosures (I have a JL1 laser and a pair of LR4 betas)

Yeah, the best workflow in my opinion is to copy your files onto an SD card using sneakernet (pulling the card and putting files directly on it from your CAM workstation).
Make sure the card is 32Gb or less and that it is formatted FAT32.

You can copy files over WiFi, but this is an area where FluidNC is still in very active development.

Some versions of FluidNC are a little finnickey with the over-WiFi job file transfers.


Thank you for your reply!

I connected power to the Jackpot CNC Controller and got it running, however, I didn’t fall in love at first sight. I’ll have to use it more.

How do I change password for the fluidCNC wifi?

And from what “view” do I know if a motor in spinning in the correct orientation? Do I look at the stepper motor from top or from the side?

Is this correct?

X1 and X2, Y1 and Y2 and Z?

Yes. Bottom left is your 0.

Too much work and to little time for this build. Currently printing LR4 parts instead.

Too much work and other stuff to do at the moment, no time for this build at the moment.

How do you make time for projects?

Oh that’s easy. You just put off the things you should be doing for the things you want to do. I call it “productive procrastination”. :laughing:

Did you get the precision system dialed in? That looks like a LR4 yz bearing mount you just printed.

I just noticed in your first pic that x an y axes need to be rotated 90 CW in that picture. Your home should be far left.

Projects get done early in the morning, or late at night… there is never enough time.

I have this build, a LR3 build and a LR4 build on the way. All of them incomplete at the moment so I am printing LR4 parts here and there.

You are spot on with the rotation! You have a master eye!

Worst case scenario is that all of my stainless steel rods are the wrong size? Like x is y length, and y is x length?

Good news is you can rotate your drawings in cam to fit your workspace, so it doesnt really matter
