Thread: Some CNC router projects.

I agree also ... looks great! Would also like a copy of the dxf file if you are feeling generous.

Cheers,

Thanks for the warm feedback. It was cut in 10mm MDF with a 4mm cutter. To get all the content(vectors) that I drew, I think a 2mm cutter would be better suited.

I want to play with making some D bits and seeing how they cut MDF. Has anyone ground their own by chance.

After having huge issues with my Y-axis stalling all the time (resolveed by re-wiring as Greg mentioned in another post) I was very happy with the finish of the cuts. My old machine left machine marks, this machine doesn't. Spending time and money on better material helps, plus youtube videos telling how to eliminate backlash with mach3.

I zipped up two versions. Those with Vectric S/W and those without.

In the Vectric version I had some errors which stated open vectors. Can anyone elaborate on this. Would it be the tool used causing the issue or just that the vectors were not closed correctly.

Edit: Sorry files were too big. You can get them from my optusnet home page

Hi Mike
Downloaded the file thanks.
It is the drawing which has open vectors. The reason it didn't stop it cutting is that there are copies of the same part on the drawing.
Try this
Edit then Select all open Vectors
You will see the open vectors as red dashed lines. In this case delete these as they are duplicates of what is underneath. This happens when you copy and paste bits around.
If they are not duplicates then use the chain command to join them up.
If it get's approval from the kids I will run it and post the result.

Cheers Rod,

I see what you mean. I did copy/paste a lot as you can see most of it consitutes mirror images around the centre point.

Something a little different. This is a machine guard that I knocked up for a glass drilling machine. The collar fits over the nose of the drill and the perspex deflects the water away from the electrics on the drill - a costly repair was needed due to the lack of sufficient protection.
The collar was turned up on the lathe, then the slot milled and the perspex guard was cut on Morphy then bent to shape.

A member of the Vectric forum posted an example of this. I was inspired to give it a go.

It was a good exercise for me. Makes you think. This one is my second try. 90mm cube.

Looks good Greg...but how on earth did you do it.

That is clever
You keep tempting us with the totary axis.
Do you just use Y and Z because I thinking of making a two axis machine with a rotary table. Morphy does not have enough Z axis travel for anything substancial so was thinking of a compact two axis and rotary axis - much like a lathe I suppose.

No rotary axis involved with this one.

Important to start with a accurate and square cube.

EDIT: Added another pic to make it easier to visualise.

That is even more impressive - cutting six faces to get a sphere.

For a bit of fun i decided to try and cut the Eifel Tower and that I work for french company had some influence on the content.
I found this in one of Benny's old threads on the Zone.

I used some flakey 3mm ply and slapped it together quickly, but it made an impresssion on my desk.

wonderful work guys,

Really clever stuff - the bar keeps getting lifted higher and higher.

cheers, jb

I did this model in Aspire. Underlying shape with a two rail sweep.

Laid out some vectors for the fluting and had them "Project onto 3D model". Same with the vee-carved design.

You just have to know the circumference and get the designs to meet at the join.

Run the toolpaths through CNCWrapper and took them to the machine.

Greg

Hi Greg,
You make it look too easy. I'm sure one needs a little bit of practise to get to that level - the circumference is changing in your design.
