Hi Anant,

Sorry to make a dumb comment but I am relating to a recent discussion in another thread...

I think that if I had spent a couple of thousand dollars on purchasing Aspire and Artcam I would be reading the manuals to learn how to use them.

My advise to splitting programs is to only post one tool to a gCode file. Or create some new text files by cut and past at a tool change and use a safe start stop routine.

A 7 hour cut in Aspire is likely to be a 3D finishing operation. The toolpath area is determined by a boundary vector. By drawing multiple boundary vectors across the area, you can create smaller areas that can be run separately.
However, if you're carving wood, it's possible that it could move overnight from stresses in the previous cut area, and you may see the border between the multiple sections.
You also need to rezero the tool the next day to exactly the same place, or you'll again see a border.
