But then again, I can imagine a caveman making an axe (composed of say wood, a chiselled rock and some roots to tie the rock to the wood) to make another axe

Yet, all I have been saying is Reprap is not special and novel.

Depends on one's budget.
Quote
If you are talking about ultra high precision CNC milling centers with all the bells and whistles, of course those are expensive. For a cheapo mill that you conver to CNC, it can be had for roughly ~$600 new. Less used.
Quote
Most modern and high quality CNC machining centers have full enclosures. Your workspace can be very clean and quiet. In fact many design studios of large companies have CNC milling machines in or near design studios, often next to some 3D printer also.

The point of my example of the cavemen was to counter your suggestion that except for CNC (mills/lathes/FDM) you cant make tools using old tools.
Quote
I stated that cavemen axe make-belief as only a sample scenario where that is actually true that you can make new tools with old tools. Plus, it doesnt need to be direct via 1 tool to the same type of tool. It can be via the generation of intermediate tools that can finally replicate the original tool. How else do you think humanity has reached its level of technological advancement if not for the fact this was true? The fact that old and existing tools are consistently used to generate the next generation of tools.

Regarding open source CNC milling? I know of so many cases.

Terry Pratchett, The Truth
The only tools a dwarf needed were his ax and some means of making fire. That'd eventually get him a forge, and with that he could make simple tools, and with those he could make complex tools, and with complex tools a dwarf could more or less make anything.

Of course, so to get mass take-up by people it has to be cheap as most people don't have the budget and space to have a machining centre at home.
No it was you that introduced expensive machining centres:
Your cheapo $600 mill is not going to be clean and quiet.
No my argument is they can't make themselves. Reprap is the first SELF replicating 3D printer. In that respect it is novel. Of course, given a selection of tools, a craftsman can make other tools. They can even make 3D printers. The novel bit about reprap is it makes the parts that would normally require a craftsman.
We are talking about SELF replication, not general fabrication, or old tools being used to make better new tools.
Yes but they aren't 3D printers, don't have the same mass appeal, and therefore don't get the same media hype.
You are arguing that Reprap is not unique, but it clearly is. It is the first affordable 3D printer and has sparked a revolution of people using 3D printers at home, whether you like it or not.

You will notice I always use the term "CNC mill/lathe", since I was being generic. There are so many varieties nowadays its hard to draw a real definition, but there are machines that combine both milling and turning capabilities in one machine so it will be able to do both. For example, the so called "swiss" CNC machines often have multiple spindles for work holding and/or cutting. Alternatively, just get a multi axis CNC milling machine and you can do almost everything. Hell, even a three axis CNC milling machine can be used as a lathe for turning. You hold the workpiece on the spindle and use the stage for tool holding, and you essentially get a lathe. This is commonly done in the industry and in home shops. A milling machine with sufficient work envelope has no problem replicating parts for itself when used intelligently.Quote
