Finished squaring up the base and placing the top. I had an issue with one of the servo motors- I dropped it and the brush keeper broke. I managed to fix it by hotgluing the old keeper in place. ...

Thanks for the replies. The brush is unharmed and in perfect working order. The plastic thing that holds it in place is what broke. I'll call around and see if it is repairable. Thanks for the...

I was installing my servo motor into my Y axis and dropped it right on the plastic brush keeper. Does anyone know how I can fix this? It's a brand new brush, so I was thinking of soldering it in...

More progress. Why does the finishing tweeks take three times longer than the building? Do the building gods realize we have wives. My wife keeps asking "why did you quit working on your machine?"...

Here is where the issue of the morning crept up. I'm buiding this by myself, so installing the back plate was quite difficult. I screwed one corer to one top side, and then started a screw on the...

Okay, new day, and I'm starting to see some problems now.

I added the second side panels for added strength, which went well. I then added the mount for the servo motor. The motor is round, so...

Getting ready to fabricate a bracket for the drive nut. I will probably add the other two bearing blocks, but it will probably be the last thing I do because it requires a complete dissasembly of...

Back to the garage. I removed the plate that will hold the router and made a new one. The original one was too short. When I made the first one, I used a precision square and a pencil to mark the...

Thanks guys. I do smell...

I'll check out the videos!

I want criticism. That's why I posted this. I planned to install a top and back to the gantry for rigidity. I agree- wood isn't ideal, but with a $10 budget, what can you do? lol If the planets...

So that's where I am so far. Now it's out to the garage to continue my build. If anyone sees anything alarming, please speak up. Better to fix it now than when it all together (and glued...)

I have a very limited budget for this project (like ten bucks or so, if the wife gets her way), so I ordered some acme screws instead of ball screws. They came with derlin anti-backlash nuts, which...

My biggest concern so far can be seen in the attached. The height of the gantry creates potential issues. First, I'll have to make it incredibly rigid because the mechanical advantage of the motors...

I'm using 25mm rods for the X axis. Probably a bit overkill, but what the heck. I want it to be rock solid once everything is built.

The Z axis was actually the first thing I built. Then I rebuilt it. Then I rebuilt it again. Getting this right was extremely difficult. Now, I'm rebuilding it one last time because the slide...

The base was harder than I expected. Getting the rails perfectly parallel was a trick. I did it by using one rail to offset the other and then drilling holes. It took some tweaking, but they are...

First, I am a complete noob. I have no formal CNC training- everything I know I've learned here or elsewhere on the internet. Three cheers for the internet!

10 years ago I bought a CNC retro kit...

Wow, was about to pull the trigger on the Rams package but then found this thread. If Jack is this much of a prick towards an existing customer, why would a potential new customer buy anything from...

Is that a frequency drive? I guess I could read the thread myself. lol

My router's minimum rpm is 16000. Is that too fast for that bit? Edit: read the description. Looks like this will work perfectly. Thanks!

It uses a 1/4" chuck. Router

By chance, has anyone found a small facing mill for their router and then just faced the mounting deck to the router? lol Kind of a Kentucky engineering solution, but wouldn't it work? Do they...

I'm building my first CNC gantry. It will have a machinging area of 30" X 20" X 6". I'm building it out of 3/4 hardwood and MDF board- some of it doubled up, to make it as stiff as possible. I...

Update:

Been pulling my hair out all day, but I found some errors and I think I'm making real progress now. The ground pass through terminal I was using to send volts to the servo was grounded to...

Hello. I got severely side tracked with this project and am just now back to finish. Pretty sad, eh? lol

Anyway, I finally have everything wired up. I have one servo cable done and plugged it...

Ok. I have shielded 4 condutor wire that's stranded and 22 gauge, but I just thought it wuold be easier to use the cat 5 connector. I wonder if I could stuff the 22 gauge wire into the connector. ...

My controller box is almost finished. I was about to install some connectors when I noticed that several commercially available servo controllers use Cat 5 cable (with presumably only a few of the...

Hmm. The instuctions say to use the 6 pin connector- even gives the Mouser part number. They are expensive from Mouser, so I thought I'd try looking around. Maybe not now. lol The cable I was...

Thank you sir. I'm now trying to find some 6 pin connectors so I can wire the connections to the motors. I figured this whole project would only take me a few days. Wrong...

Heh. Yeah. Well, I got it. 24VDC with no smoke, no popped breakers, no scary noises, and I had the TV, computer, and ceiling fan all on. Hey, I learn by doing (and sometimes failing), and I...

I'm pretty sure it was because of the neutral and hot wires being backwards at the wall plug. I put them around correctly, and the transformer no longer makes a humming noise, and the cooling fan...
