If it were true then Universities and schools wouldn't exist. After all everything taught
in school is a "Google search away".
There are a lot of extremely knowledgeable people out there with little
formal education. Universities and schools are not the only way to
learn. They make
But having used both but with sometimes 6 to 8 months or even a year between
uses, I can tell you that a slightly automated manual lathe with an ELS is a
leap forward in ease of use compared to booting up a PC, running the CNC
application and then trying to remember what G-Code/M-Code did

Hi all,
A quick look at web sources seems to indicate that the EPP on some
motherboards simply doesn't work.
In my case I'm having problems with a 7i43 -5i33.
Has anyone gotten the 7i43/5i33 to work with a D525 intel board? If so
would you please share the magic incantations necessary.

What exactly is open source? In a way it's LinuxCNC but only a few guru's
really understand what is happening under the covers because it's so incredibly
powerful.The MESA cards can be modified since much of the FPGA information
is published. But unlike MACH3 where a simple checkbox

As I understand it steam engine does not have the best efficiency, pyrolysis

Printers talk postscript while CNC machines talk g-code, well not always but
quite often.

Maybe cnc routers could be a "plug n play" usually the setups are
relatively easy, materials are more or less flat sheets.
