(A company looking to buy and willing to pay for a commercial machine with commercial support and out of house service is a perfect example.) As to who will support, if a manufacturer were to chose to use Linuxcnc as their control it would be up to them to support it. (See Tormach as an example). On a retrofit machine the support burden would fall on the retrofitter (you if you did it yourself, the same for Mach.) If you want a supported turn key retrofit system with support, it is going to cost you a pretty penny. As will any good machine with commercial quality support. (and you won't find any machines running Mach in that category either.) But for a company looking to retrofit old or unsupported machinery, using in house support resources Linuxcnc is an excellent option. >I can't tell people to come ask questions on this mailing list.

Linuxcnc doesn't require old hardware. Used PCs are often suggested, because Linuxcnc's PC requirements are not all that demanding, such that older PCs are generally adequate. But because some PC designs are not well suited to running real-time getting a "good" one can be a bit of a role of the dice. This is why testing a few old PCs you may have at hand is worth while rather than going out and buying a new one that may or may not work better. Linuxcnc is far more hardware agnostic than Mach. As far as I know Linuxcnc runs perfectly well on most new PC-hardware, and a parallel port is not a requirement, unless you want to use one. >LinuxCNC is like Apache and such in the 1990s.

Numerous robots work that way. I know I shouldn't feed the trolls but... Todd Zuercher P.
