The motor mounts to a stand-off/adapter (square block item) and the stand-off/adaptor mounts to the plate on the side of the machine.
The motor has a coupler on the shaft that also interlocks to it...

I am a long time builder/commenter and now nearing the end of the journey.
Here are a couple pics of the mostly built project -- bone stock pretty much.

Thanks Dave. I found some of the typos (and I am sure others did too) and passed them on to Bob.
He actually has an errata/typo thread here I think.

I got the windows installed in the flip up lid...

DCreu, What do you mean when you refer to the latest revision of the Momus plans? I am at V2.1 (Z axis upgrade to thrust bearing)

I've been horribly sidetracked on my build, but am getting some...

There are several variables to your questions.

What Software are you using?
What motor drive are you using?
What is the runout of your spindle/router?
Are the parts uniform? i.e. is the 49.4 x...

Nice work!
There seems to be a trend in expanding the Momus.
I have kept to the original size and am in the base/top painting/finishing mode.
Metal work is 98% or so done.
Electronics about 85%...

I've seen no information about a V3 unit.
Bob hasn't updated the webpage in a while.

I am in the base and top prime/sand/finish mode and need to revisit the Z mount ro do this.
Easier done while the gantry in on the bench than later.

The metal work was much more fun than the mode...

How gooey is the goo?

If it is like cold syrup, you could try putting all the scraped out goo into a disposable container, mix in the rest of the 'right' material and salvage the stuff,
You would...

My 'fix' is to take some of the scrap that has the beveled top edge and put it in where i made the mistake.
Fill and sand as needed. Move on with the job.

I cut the pockets on my mill before...

Another nice looking build and it looks like you didn't make the mistake I did (reveal in a few lines).
Tip #37 - don't get sidetracked or your Momus will sit alone like mine has...

I got...

Outstanding work, well done!

Serves to motivate me to get back on my build. I changed roles in the company and had about 50 other projects get between me and the Momus
Then along comes a...

Clever!
This would depend on the spacer/washer combinations to give a tight fit in the tube spacing.
For those of us who are building, that is minor compared to the benefit of an easier adjustment....

That's great news!
I need to get back on mine but, it is on the new support/table with locking casters now.

I am in the process of moving all my 'clean' computer stuff upstairs into the...

Just an idea: Is the parallel port set up for bidirectional operation via the BIOS settings?

Of course that question is null and void if Mach 3 does this for you.

Sorry to hear about your run...

A good innovative approach. Well done.
My build is at the 2.0 stage, have the 2.1 updates, and now a second choice -- and I also have a lathe.

Any landing you can walk away from is a good one. ;)...

You could ask folk at the Makers Shop for assistance. I am sure they will be able to guide or help you.

The important point is to make progress on a daily or weekly basis. Projects stall very...

Outstanding! Bravo!
I have read several articles on using/adapting cams to the spindle mounts to do just what you did, and more.
It is good to hear the solutions were simple issues and with the...

Hmmm...
Could the movement forces be increasing as you move 'downstream' from the motor?
Because the machine runs open loop, if the force in the direction (with error) is increasing, each step...

Greetings Segue!

No official DXF (or Gcode) but one member did cut his wood on a larger CNC. Search this group and maybe he will share.

You are on your own in expanding the cutting area but...

Outstanding progress and results Mac!

I came to a realization this weekend that the table I was employing for my 1st CNC build (Kleinbauer Brute -- ugh!) was almost perfect for the Momus. In fact...

Mac,
Could the surface of the epoxy vary enough also to cause your dial movements?
We will have to assume a moderate uniform expansion due to temperature over the surface of the epoxy field but it...

Great work!

Most of the parts are symmetrical in layout but a few actually have different layouts on each side.
Bob mitigated some of that with the 'over drill' technique and in some cases the...

It is official, the frame supply in my project does have isolation between DC return (-) and chassis protective mains AC ground. I have no continuity between the safety ground and the -V on the...

Well then, that is puzzling but it also may explain why so much industrial work has opto isolated signals from OTS (off the shelf) PCs and servers...or the practice is to opto isolate somewhere in...

He can't be single, there is plant in the window and pretty stuff in the kitchen sink window.
Then again is Cheeto confirmed to be a male??? I'd love to see some fe-types bring their perspective to...

Mac,

A+! Good find on those mounting screws.
I have seen nylon/plastic screws in those type of supplies -- I am addicted to taking stuff apart, been doing it since I was a kid.

This supply...

Congratulations! There is nothing quite like seeing it all come together and start to make something you need.

+1 with cb_designer's comment on cutting tool length. If your speeds are very slow in...

Mac -- regarding your DC (return) and the chassis ground (earth).
You are correct in that they are two very different items with different purposes.
I have been employed in field service and...

More stunning planning and work. Bravo Mac!

For the casual readers, the black residue mentioned in Mac's polishing directions is aluminum oxide -- rust.
Aluminum rusts black.
Iron/steel rusts...
