Hello routalot!!! Hope all is well.

Yes, I'm very eager to get this one up and running and getting cutting for my next machine! I guess I could say I've caught the "CNC-bug". First thing will be...

Thanks Peter,
I actually switched from the SHS to the steel angle because of that. Well that and the fact that the quality of SHS you get here is appalling,making it hard to alighn holes on other...

Z axis assembly....

I have considered that and actually, one way around the dust build up on the rails would be tiny brushes mounted on the moving assemblies to constantly bush the dust off, but I highly doubt it would...

Thanks for the suggestion but I've come a long way to do anything about it. I'm fully aware of the short comings of a moving gantry CNC and if I had to do it all over again, I'd probably do a fixed...

That's to provide room for the Z-axis assembly although they are much further than necessary in the photo. I adjusted them later (more photos will be uploaded shortly).

I'll try to cut as slow as...

That's a something I hadn't taken seriously before that has started to haunt me as well! I might take the route of the enclosure coz vacs are loud and require additional power to run. To keep noise...

So far I'm pleased with how the machine is turning out. All the rails glide very smoothly! I'm kind of in a hurry to get it up and running now because there's a huge line up of work waiting for it. I...

Got some work in a few days ago.
Behold the Z - axis rails. I'll be working on the Z - axis...

If you're talking about the X - axis motor mount (which drives the gantry), the pieces if angle iron I used for attachment secured it quite strongly. I'll see how it goes as I build on.

It is...

Last few photos.

More photos.

Some of the photos seem to have been rotated. My apologies.

Some photos.

For some reason, the sketch up model wouldn't upload. I'll keep trying. The problem I had before where the motion of the axis wasn't smooth was solved. I got better quality bearings and smooth pipes...

Some uploads.

Hope everyone's okay. After a long time busy, I finally managed to score some free time and resume this project. Made an entirely new design using angle iron. The square section wouldn't work because...

I thought he meant 4 centimeters. I think we can all agree that 40 microns (4 hundredths of a millimetre) of deflection is more than perfect for a DIY machine, besides, the equipment required to take...

I think I can now move forward now that the linear bearing issues are history.

Final (hopefully) rail.

Hello George,

You and GME are having me confused with reg.miller. He's the one using the I-beams, with an almost complete machine. I on the other hand haven't started my build. I was having...

Were your I-beams still deflecting at this stage of the build?

Thanks for the links, I use windows and as I type this, I'm installing freeCAD so I can have a closer look at your designs. I'm sure I'll get answers to a few questions I'm having, maybe even ideas...

Hello Miller,

I see what you mean from the videos and also agree that "closing the box" makes a huge difference, which is why I did it right from the start. I also had a closer look at your...

Never mind. After taking a closer look at the photos, I found the answer. Your design is efficient in that you could fully support your I beams from the inside. I on the other hand, don't have that...

Please send the model. I'll figure out some way to check it out. I'll do the alignment as soon as I get a few hours to spare. In the meantime, I'll be working on a revamped design of mine in...

That's not far off from how mine behave, except I don't think mine are nearly as tight as yours.

You did but no worries. I just wanted to have a look underneath.

WOAH!! Is that how much your X-axis I-beams were deflecting downward? That is crazy!!! Waiting to see what mine will be like, good thing I've got an idea of a solution in case mine deflects...
