3-axix CNC machine......

I found this by accident while looking for something else.

Go to 'robotics' and scroll down.
Might be handy?!!! :roll:

Yep - that's the same one as the Farnell one...

This is the one that when I emailed them asking about .

They said it wouldn`t do engraving

I'm sure it DID say it could engrave.
They should make their minds up.

Here it is...

Accepts standard HPGL code (not circular interpolation codes though) for use as a simple plotter or for LIGHT engraving work.

Defintion of LIGHT being???????????????????

I asked if it would engrave aluminium panels for fascias of electronic equipmanet. They said no.

I kind of suspected there might be a possibility it would, but was`nt going to spend nearly £300 to find out.

I don't quite understand this - surely it is a problem with the actual engraving hardware than the transporting tool?
In the diagram - if we replace the drill with equally small engraving pen - then shouldn;t it work?

It may have something to do with slop in the bearings. If you look at the pictures it seems to use drawer runners as the surface slides, which may mean that if you engraving something that is realativly hard then the mechanisms move & create error.

Who knows. I`m not trying to be negative about this, because a simple one stop solution to this would suit me down to the ground. I spend too much time trying to get the right old parts for valve gear without having the hassle of doing it for an engraving machine as well.

Its funny that you can come here & people just give anyone free advice, but if you want to DIY CNC stuff everyone seems to want some money out of you!!

Check this out dudes....

I just got the plans, very well done, all 3 machines are inexpensive to build from hardware store parts. I think the big one is enough to engraving front panels at home :green:

cheers!

Nice!

..but many of the parts are very hard to find - at least here in Denmark. I'm currently looking into the Basic540-kit: http://www.step-four.at/e_index.html

There were a few machines on ebay last I looked. Probably out of China, and you'd need to be careful you picked one big enough...... but I thought they'd be cheaper than building in the long run....... not that I'm in the run.......got too many other dreams... :green:

Do you have a rough price on that 540 ??

Also I thought you had already built a CNC machine ??

Yep, I made my own engraver:

.. but it is somewhat limited in it's way of working, so I was thinking of building a MK-II version, when I came across the basic540. Pricing is a bit hard to find, but a rough estimate is €2500 for the mechanics, unassembled, without the spindle/motor section.
