Re: [CAD_CAM_EDM_DRO] EMC Problem and Question

Jon,

Thanks for the advice, I must admit I am a mere novice when it comes to Linux.

Thanks Again,

Victor A.

Unfortunately all of my g-code program files have long descriptive file names, I have a short memory. The new EMC recognizes the files but has truncated the files names into short file names, like the old MS DOS. Is there a way to get the Debian ver 4.38 to use long file names?

Huuuuh? The only possible way I can think of this happening is that the
old files are on a drive with
a MicroSoft file system. (More follows.)

>2nd issue: The new Debian ver 4.38 supports USB, and I have been using it to transfer files from my Windows system to my EMC System so I can make parts on the mill. The problem is when I plug the USB drive into the machine I can access the drive and transfer the files, but if I need to remove the USB drive, go back to my Windows computer and make changes, do a proper eject on my Windows computer with the USB drive, then plug it back into the EMC machine, I cannot get it to recognize the files on the USB drive a second time in the same session. I then have to reboot the EMC machine, so that the system will read the USB drive and I can transfer the file or files.

Ah, now it becomes clear. Your Debian system is apparently
mis-recognizing the file system on the USB drive,
that's why the file names are getting trashed. You need to learn more
about the way Linux handles removable
drives and foreign file systems. The mount command allows you to force
the file system type in cases where
related file systems are partially intercompatible. You can do this
with the -t option on mount.
It may be that you need to reformat the USB drive to, say, the ntfs file
system to make long file names
more transparent.

EMC2 is vastly more flexible, and allows infinite mixing and matching of
I/O, axis drives and human
interface devices. It has become a bit more complicated and finicky due
to this, and the documentation
is still catching up. But, these are true improvements, I assure you.

Also, EMC2 has fixed several long-standing bugs in EMC1, and there have
been additional fixes coming
along steadily, in the area of better motion planning and lookahead,
smooth profiling, higher-speed
machining, etc.
