Whats up with this ?

[Sampson Jones]

This line shows up when opening in sheetcam version 6.1.57 on lineux command candcnc . This same drawing opens perfect on sheetcam version 6.1.74 on another windows based computer . I was told to only use the sheet cam version that came with the command system and not my old windows bases sheetcam . Can somebody tell me why this line is showing up and why I have to use the sheetcam that came with the command ?

I'm not sure what is happening there. If you send me a copy of the drawing I'll take a look and see if I can figure out what is going on.
As long as you use the same post processor and path rules you can use your Windows copy of SheetCam. A quick way to transfer your tools and rules to the Windows machine is to save a job (File->save job) on the Linux version then load that job into your Windows version. After loading the job go to File->save default toolset to save your tools.

The cause was the “arc fitting “ needed to be set to zero in the tab in the command cnc . Thanks to Tom at candcnc for the soultion . Thanks Les as well for giving us sheetcam
