Please add links to where you got the belt and the model number.

I realize now that you made the pulley.

What kind of coolant are you running? Did you say somewhere I didn't see?

Joe,

Thanks for posting your stand / pan plans before. I used your ideas along with Russ' as well to build mine and I am now to the point where I am ready to epoxy / fiberglass my pan but was...

I built a table-top / benchtop CNC machine using plans from MomusCNC: momus CNC | benchtop DIY router plans | home page
There is a sub-forum here with other people's builds:...

I just wanted to say thanks to everyone for the suggestions.
Unfortunately I haven't had time to try any of them at this time but I am hoping to tackle the issue this weekend.

Thank you for the reply. Gives me an excuse to buy more tools since I don't have any ezouts at this time.

My question just goes to show my ignorance of all of this.
But we all start from...

The manual says it's a 5mm set screw although it definitely seems to be a 2.5mm. I can't get it to break free and it slips when I add torque to it.
Does it actually need to be removed in order to...

Here's a picture of the part.

Can anyone tell me what size the hex set screw size is supposed to be on the inside of the G0704 gear select knob?
I stripped the gears on the inside and can't seem to break it free.

What seems...

Yes you can do it with only a file and hacksaw and lots of elbow grease.

Star san is an acidic sanitizer.
It eats copper up pretty fast in my experience.
Wonderful for sanitizing beer equipment but I wouldn't think it would be the greatest idea around metal equipment.

On the bright side the delay let me make two batches of beer :)
I have a Bee Cave Robust Porter going now. Man is it a active ferment!

It looks like that using the Bosch Colt as my spindle has...

Originally I had planned on using a separate BOB and drivers to drive the Momus directly until I moved them over to my G0704 that I am also going to CNC.

Then I came across the MX3660 and it...

Well I got a successful pour of epoxy on to the bed of the machine.
I couldn't get every last little bubble out of the mixture but I think it will still be a very serviceable reference plane for the...

Does anyone have any tips on the best way to attach the motor leads to the flexible stepper wire?
I was planning on soldering but needed to ensure that I had them run the best way that I could.
It...

I got all the uncured epoxy out of the bed. It was a bit of a pain since it was so viscous but with lots of pushing with a paint scraper and some soaking with rubbing alcohol the tackiness is gone. ...

Thanks. that is what I expected to hear actually.
I consider it a life lesson in how to not mix epoxy :).
What should I do with the goo?

Do you think there is any merit to attempting to mix some more resin into the existing layer on the base?
I have 16 ounces left after all and the mixture on the base is still gooey.

So I have a slight problem with my epoxy base pour.

I mixed up the correct 2:1 ratio based on the instructions but unfortunately mixed the bottles up.
The mixture was then a 2:1 ratio of hardener...

After putting some padding on the cover it appears that I have the clearance after all without having to modify anything with my particular set of steppers.
I think I have a little over 1/8"...

Status update:

I completed the Z-axis spacer and did the bearing preload.
I had to stop there for the night since my 10-32 x 2" bolts for the Z-axis are not long enough to reach through the...

Well I got everything rolling freely and installed the X and Y motors and belts.
Setting the windows is a bit tricky when trying to keep silicon from getting everywhere.

I am doing both of the...

I didn't set the windows yet but I did mess with the gantry some more.
It appears that it isn't quite square and I am rubbing on the left side if I square it up.
I am going to have to tweak it some...

Here's what the cover looks like at this time.
I have it all painted up and ready for the windows to be set.
I didn't have time before I had to leave for Thanksgiving but now that is over I plan on...

Here's what my gantry misalignment looks like:

Couldn't you just cut a piece of wood and glue it in to fill in the extra hole in the base?
Seems like a much easier solution and you don't have to tell anyone you did it :)

Nevermind I misread...

When you say 'outside of my build' do you mean the enclosure?

I have my gantry rolling on the base now but it seems that the left side is 3/8" farther forward than the right side.
I need to...

Ok I found the relevant information on page 170 of the 2.1 plans.
Not too tight and not too loose :).

How much resistance to rolling should there be for the X and Y rails?
It seems with some adjustment it is rolling pretty freely but I can tighten down the bearings and then it becomes hard to push....

Mac,

Thanks for the pointer to the errata. I think Bob has those all corrected in the 2.1 download.
I am planning on adding the thrust bearing mod to my Z-axis as well.

I bought some plate...
