since it is silver I'm guessing it will turn black over time

you could tin it instead

Cool-amp is the dreaded silver - it creeps across insulating surfaces and turns black.

I bought the CNC 6040 last year:

My wife has a clothing store and the facade sign was something like 100 USD per letter, so I bought the machine to mill the sign myself. Worked out gr eat, and now I can do all kinds of funny stuff (If I ever get the time to)

The MACH3 comes free of charge for the CNC 3020 or 6040 etc. I haven't dug deep into the SW, but I think the MACH3 outperforms GRBL by a long shot. I have the probing tool to, so just place the PCB on a support plate, probe t he edges and surface, and it is calibrated to provide better results

Nice

Actually the CNC 3020 can be retrofittet with a 3D printer head, so you can even do 3D printing

Awesome. I have a couple of silver carving platters to touch up, and that stuff looks great. The MSDS says sodium chloride, calcium carbonate, and silver chloride, so no nasties in there (e.g. cyanide).

Cheers

Actually this is just an example of the one I bought. A collegue of mine ha d bought the CNC 3020 and he ran into problems right away since the cables for the steppers was cheap grade, even single core AFAIR.

So I spend long time scoping the CNC forums and found one with decent quali ty (it cost a little more)

yes MACH3 can do much more than grbl, but if all you want to do is a bit of simple milling and don't have a parallelport it'll do ok

I once thought it would be cool to mount a near field probe to the CNC and let it scan a PCB for radiated EMC debugging

Like this one:

Something like that can be done by a robotic arm instead. 10 years from now you don't use standard probes, you just tell the scope which test point yo u need measured :-)

aka 'flying probe' method.

That's how they test prototype PCBs without NRE for a test fixture.

just stick scope probe on the spindle, get the coordinate from the gerber and probe away. Stick a cheap usb microscope on there if you want visual
