RE: [CAD_CAM_EDM_DRO] EMC in Portland

If you are familiar with Linux, EMC is not hard to set up. The big
difficulty people have is getting the RT kernel running and that is mostly a
matter of reading the instructions and following it exactly (something we
men tend not to do to well).

I am Running EMC with steppers and can get speeds to about 90 ipm. I don't
run that fast as I have a resonance at about 54 ipm on my Y axis, but I
think that is caused by my driver/motors/machine not by EMC. The 90 ipm top
end I am seeing I think is caused by my 36 V power supply. I think If I were
to move to a driver that used higher voltage I would have more top end, so
again not an EMC limitation.

Yes, you can set up Linux/EMC so that you can copy files on the network. I
am running mine with the SAMBA server and can read/delete/add files on the
Linux box from any 3.1WFW, 9X, NT, Win 2000 Windows system on my network.
