Hi, I am using autocad 2011LT to plot to universal laser cutters. We have three different lasers: M300, M360, and V460. When we plot rasters to the M300 and V460, we often notice a shift in the raster cuts from the vector cuts. All of the rasters are always shifted in the same direction and by the same distance (anout 2-3 mm). This shifting started happening about 6 months ago. We have not noticed this shift yet in the M360, but believe it has something to do with the autocad settings. We have cleaned out and reinstalled all of the laser cutter drivers and still have this issue. Has anyone ran into this issue or have any advice?
