If the PC is unplugged without properly shutting down, the tool library in Sheetcam may be lost or corrupted. This may cause the tool library panel to display “T1: 0.030 kerf plasma” instead of “45A 16AWG Steel”. To fix this issue:

1. Open Sheetcam 2. Under the File menu, select Open Toolset 3. Navigate to Desktop/Program Backup Files/ and select the file: commandcncHYP 65-85-105 to import the tool library. 4. If the names aren't fixed after importing the tool library, click on the table icon in the Tools window, and de-select 'Automatically generate name' 5. Under the File menu, select 'Save Default Toolset' 6. Make sure the system is shut down completely before removing power!

For catastrophic damage to the Sheetcam software configuration, use this Sheetcam Setup PDF to restore the original program settings.
