Hi,
I purchased a SH40 Laser online from Shen Hui Laser on the 9th of Jan, started using it last Monday. The laser fires ok @ x=0, Y=0 but if the laser goes further right, let say X=60 as starting point, no laser mark was shown.
I did an example by drawing a rectangular shape Length = 200mm (X direction), Width = 80mm (Y direction) to show how the laser mark fades away as it goes further right and I would like to know what actually is causing this? is it out of focus?
