Home made CNC mill (and some products made by it)

[gcamlibel]

I have almost finished building my home made cnc. And tonight I tested it with a pen. The test was successful. I want to share first photographs with forum members.

This is my first CNC application and I am waiting suggestions.

You can see some other images of this tool at my homepage http://gunol.otocamlibel.com

I like the design concept.
The first two things that spring to mind are
#1 You are using chipboard which has very poor structural properties. As a test of concept it is fine, but re-make the machine from MDF.
#2 the spine is just one sheet with nothing to stop it from bending. You need to have pieces at right angles running all the way from bottom to top to prevent flex here.
Change those two things and you are off to the races!

Pretty freakin cool man! Are those drawer slides? How thick is that OSB?

[yukonho]

I visited your homepage. Very nice photo's!
I could not find pictures of the machine though.

I LIKE IT! gcamlibel very nice work.

May be some glued (glue doesn't do much on OSB but it won't hurt) and screwed wood corner braces on the boxed portion of the head.

Keep up the great work and keep us up to date on your progress.

Answers for Hobbiest:
thicness of OSB is 18mm,
and yes sliders are drawer sliders.

(Thanks for all forum members for sharing their knowlage and special thanks for yukonho's support and suggestions.)

Hey I like that. Very simple design. Constructed on the cheap. Thats a good thing. If people can make one for real cheap (atleast there first one) then maybe more people would be building these things. At those prices it could be a school project for the kids.
Hows the accurecy of it?

Cool!
Whats the XYZ travel?
I would suggest another piece of tape to hold down that workpiece.

First of all thanks for your comments.

I will securely connect z axis with other two axises. here I made just a test drive with this tool. Therefore I cannot say anything about its accuracy before finishing the tool.

Today I will add a base in order to connect z axis with others. and I will put a dremel tool instead of pen to check its cutting ability.

After this modifications I will post new pictures and accuracy info about my tool.

There is a test output of my pen router attached
there is a ink spot at left side, it is just becouse I paused the operation when pen is there in order to take a picture...

and here the answer of Bill:

x movement is -20cm to +20cm total: 40cm
y movement is -20cm to +13cm total: 33cm
z movement is 0 to 13cm total:13cm (but can easly increasable)

Thank you for "another piece of tape" suggestion

Looking pretty good. It doesn't appear to have much backlash. I look forward to seeing pictures of it finished with the dremel on it. Keep up the good work!

Looks great!
How much did the materials cost ?
