TB016 Rev1 Restore Previous Version CNC7 After Update
Overview
This document describes the proper DOS commands used to restore a Centroid Milling Control to its previous
version of CNC7 Software in the event that the update procedures have failed or there are other problems
Centroid tests update disks before shipping for any possible problems Although it's not likely it is possible
that magnetic sensitive material going through the shipping process can be susceptible to damage The
following instructions are valid for software v7 02+ and assume the update procedure was tried only once
Because the update procedure performs a backup trying to update after a failed attempt may result in the
inability to restore the previous software
Note Before performing an update CNC7 software DOS checks to see if there is 100MB of free space If it?s
not available the backup process will only make a backup of the configuration files instead of backing up
everything CNC10 software Linux just makes a backup of the CNC10 directory
Â
Steps
1 Enter DOS
From the main screen of the CNC7 software press CTRL+ALT+X
