We have customised NCdrill legend and placed in Allegro_site locaiton, which is our server and is with readonly rights.
ncdpath variable points to this file location.($Allegro_site\pcb\nclegend)
nclegend_file point to the customised file name(my_default-mil.dlt)
With this we are able to generate only the first time the NCdrill chart. Second time we get error E- *Error* renameFile: file exists.
We deleted the NCparam.txt and it regenerates fine but wondering what's causing this issue.
