There is a way to do this. I have not ran this myself but when the technician came out to set up my machine,
he showed me this file and did an air cut with it to make sure it worked and it did.
Have a look. It does what you want. It trims the over size sheet to fit in the 5 x 10 table. I also use
a CS45 - 510
Hope it works for you,
PS, I am trying to attach the file and have never done this on this forum. If it does not work,
email me at email@example.com
and I will send you the nc file.
