So you plan on mounting the 3030 on top of a table/bed without feet, is that correct? I found one like you are talking about I think (see attached pic).

That build is here: FandZ's 80/20 and nearly completely bolt together CNC build LINK

By the way, I did see some that used 4" CRS on a 3030 on the Y-axis so it might not be a problem on that axis after all: 8020 DIY CNC - Full Motion Test Youtube LINK

And his build thread can be found here: CNC Wood Router Project Log LINK

Yes that is what I was thinking. I want to build cnc with about a 50"x65" cutting area. And just trying to plan it out a little before hand so I don't waste to much material, money, and time. I'm glad I found this sight and thanks again for all the help!!!

Default Leadscrew Nuts

Noob, you have a really fine looking machine. What type of nuts are you using on your leadscrews to help prevent backlash?

I'm using these that are made out of delrin and have the hole pattern to match the 80/20 extrusion: 1/2-10 ACME Nut, 5 Start
[CRP109-00] LINK


Some prefer the Dumpster CNC, but if you use those you'll have to figure out a way to mount them. That wouldn't be difficult, but just mentioning that they don't bolt right up. Dumpster CNC ACME Anti-backlash Leadnuts LINK

I'll have to clean them up a bit because I've tweaked it a time or two.

Got the top on, but have to figure out what I'm going to do about a spoilboard: DIY CNC router controlled with XBox 360 controller LINK

Not sure if I want to use T-Slots on the spoilboard or put a couple rows and columns of holes with 1/4-20 tee nuts to hold the wood down.

I've got some of these from Amazon, and I may use them instead. 1/4"-20 Hurricane Nuts LINK

Every one needs to check out Noob's website. It has the best step by step router build I have seen thus far.

Thanks for looking

It is a great idea to look at those step-by-step instructions because it can save you some time on assembling and dis-assembling; also they clarify some confusing parts of the build.

If you look at the attached pic, you will notice that I forgot to put the t-nuts into one of the extrusions, and also the bearing block is on the wrong extrusion.

That part of the assembly is an example that wasn't very clear. Directly behind where the t-nuts go, there are 2 screws that attach the 2 extrusions perpendicular to each other. In other words, in that pic, you see a vertical and horizontal extrusion attached like a "T", and a screw attaches those together. Then the t-nuts go behind those screws and the purpose of the t-nuts is to attach the motor mounts.

Sorry if that explanation is confusing, but you can see how it is supposed to be in the next pic.

Default Thanks

I'm new to the site and was lurking around and found your thread and your site. Thanks for posting the vids. I have the same kit (bought it over 8 months ago). I'm just now getting the time to build it and the edrawings do leave a little to be desired. I understand better after watching. Thanks again.
