DIY CNC table (paging HOOD)

Just a diamond stone dresser on a spring loaded arm deployed with an air cylinder would likely do for marking. Maybe even just using the plasma cutter at a fast rate of knots and low power would do, never tried though.

When i build mine i intend to have similar set up but use a cheap spindle

My two cents worth.
Mine is a plasma / router and flat bed mill. Flat bed mill to mill alli, so far have milled 20mm alli on it and no trouble. I have servo motors for speed when plasma cutting and the torque required to push the cutter through the material when routing / milling. I have enough torque to break a 6mm solid carbide cutter at the shank. No need to ask me how I know this. Now is it possible to do both, absolutely YES, I have managed to prove that for myself. Do you need it well it is up to you. My slats are 65mm by 3mm flat bar spaced 50mm apart and over the length of 1500mm have a bend of 50mm. Dross can be cleaned up with a penumatic chizel rattling the slats, this gets most of the dross off. I have a penumatic scribe on the plasma head. The routing head will have the machine spindle and a MQL system for when milling alli. The plasma head will also have a USB microscope connected to the computer and run by 'scanything ' which is from 'sheetcam' and yes the drawing must be black on white for best results.

I am starting my upgrade build and have photos of the 'Y' axis gantry now after welding in my post 'BY BY old friend'. You can look if you please. I have posted pics and have vids of the my machine cutting 20mm alli and marking plates in other posts, probably @Hood will know how to find them. My upgrade will be vastly different from what it was initially and incoperate many improvement that I have wanted / used and be much more user friendly and flexible.

If you want to do all this on the cheap, some advice 'DON'T' . Is it easier to buy a completed machine and get going 'YES' can you spend the same money building one as buying one 'YES'. You can get a completed machine ready to go without the frustration of building one and it comes with warranty. So why build one.
It is and can be very rewarding to build something of this caliber and it works, but the biggest difference is that you can build more into it.
There is much detail on the net regarding people that have built one and that works. I built mine about 5years ago and kits are now even more plentiful. So if you are game have a go, what could possibly go wrong

In my efforts to be a tight fisted so and so i have come across this

Which is based of this design for a 3D printed router

i am doing a wee bit more research into the machine as it does look like a viable option if not an overly robust option

Think someone on here made a plasma from printed brackets and standard wound tube.


Edit, I now have a bleeding speech impediment whilst typing , should be round tube not "wound" tube
