You may ‘nest’ your parts before sending us your file, using your CAD software if you like, all we need, and specify is that you allow a small border of uncut material around your cutout designs. This is called a ‘safe area’, by some laser cutters. We only need a small border of 10mm all around. Or just make sure the material you use is 20mm larger than your cutout area. This is simply so we dont have to spend too much time aligning your materials on the laser bed. We can cut right to the edge of a sheet of material, but it will require some double checking of the placement of material. As mentioned, our laser size is 1200mm by 1200mm. The machine can take oversize sheets (4 ft, which is 1220mm), but will not cut on the extra 20mm width. All small parts cutting is preferably done in the front 600mm by 1200mm wide, this is simply because is easier to pick out the small parts without reaching way over to the back of the machine! Source.
