Hi guys
I was just wondering who here has retrofitted any big commercial machines
with linuxcnc and who actually uses there machine to make parts everyday.
I work in machine shops and am using fagor/ siemens/ controllers all the
time. and I am retrofitting a cnc mill myself as a project and so I can
start my own machine shop at home on the farm.
Stuart Stevenson made these videos when he was previously at
MPM in Wichita, KS.

He had 2 GIANT Cincinnatti 5-axis mills there, one
previously retrofitted with OpenCNC, and this
one with LinuxCNC. He built a 5-axis error compensation
matrix to correct motion alignment errors
in the machine, and added this to the LinuxCNC code. The
demo with the 3 indicators on the big ball
shows that the errors are well compensated while all 5 axes
are in motion.
MPM also had a colossal Giddings and Lewis horizontal boring
mill, also run by LinuxCNC.
He later left MPM and set up his own shop where he has a
couple more of the 5-axis Cincis, and a bunch
of other machines.
I don't make parts every day, but most of the work on my
Bridgeport is for commercial production.
But, since I am the only guy here, I have to do all the
other work as well.
I'm helping a local guy retrofit a Hardinge CHNC I lathe
which will go into commercial production when
we get it finished.
