Welcome to the forum Chaz, your biggest problem converting a 3D printer to use as a CNC machine is going to be making it rigid enough if you are intending cutting aluminium with it. Have a look through the build logs as it will give you a better idea.

Understood. The frame that I have is fairly rigid but not enough so as it stands currently - perhaps light plastic work or similar - nothing more.

Can anyone tell me if something like a Kress 1050 is suitable for light alu work or should I just go and look at the 2.2KW type spindles?

Thanks

Yes

If you are looking at a production environment for machining aluminium then a cress may not be your best option but for occasional use they seem to be ok as the video shows. Not used one myself so can't speak from personal experience.

Thanks - its just a starting point - will check to see whats available once I am ready to buy.

So, taking a bash at my own design. Nothing special - keeping to basics - using this CNC as inspiration - will cost it all up and see what it will cost. Welcome to comment / crit etc. Inspiration from here (ie, this is what I am trying to copy). http://www.mycncuk.com/forums/router...ade-cnc-4.html

The bed is 120 x 30 profile, 1 meter long and 4 x 120 width. The other section is 120 x 60 profile - 480mm across and 200mm shorter segments for the sides. Of course still a load to do and look at.
