Unable to open nc files (Resolved)

[cncsnw]

I never have had an issue. When you point CNC12 to the file on a USB drive, it immediately copies the file the C:\CNCM(T)|NCFILES directory.

CNC12 only does that if you have bit 0 of Parameter 4 set (e.g. P4 = 1, 5, or 9).

Having that bit set is the standard configuration, but it can be turned off if you prefer to just use the file where it sits.

There is also an option (via bit 1, value +2) to "cache" CNC files. With this option a temporary copy of the current job is made on the c: drive, and the control runs that temporary copy, but it is deleted and replaced when you load a different job.

Interesting, what is the purpose or thought he nd those options? Practicality?

The caching option (P4 += 2) is mostly used with large jobs on network connections.

Having a local copy while the job runs means that the job will not be interrupted if the network connection is lost while the job is running.

Having the local copy be temporary ensures that the control's hard drive space does not eventually fill up with very large one-off job files; and ensures that there is only one "master" copy of the file.

If the caching software feature is working correctly, then edits (F6/Edit) will open the original file over the network, and not the cached copy; and any time the original file has changed when you try to run it, then a fresh copy will be downloaded.

Thanks for pointing out those file features to us Marc!

Sorry for the delayed response guys!

Turns out it was an issue with the USB stick, I switched to another one and the issue went away.

Thanks for the help and sorry for the fire drill!
