Background
The size of the entire Cut Bed is 19"x13" (485mm x 330mm), however the Cutting Area is only 18"x12" (460mm x 305mm). The Cutting Area refers to the area on the cut bed in which the gantry can travel, however this does not mean that a 18"x12" panel measured outside can be cut using the WAZER. This can create some confusion on the limitations of this measurement.
The 18”x12” work envelope is the largest extents that the center of the nozzle can travel, this means that If a 18"x12" rectangle is imported into WAM, you can only use the Centerline or Inside Cutting Paths, the gantry is unable to move to the outside edge of this rectangle. See the picture below for a visual example of the Cutting Paths.
If the Outside Cutting Path is selected the nozzle will be assigned to move on the outside edge of the 18"x12" rectangle. The gantry is not capable of moving outside of this rectangle so WAM will let you know it is not capable of cutting that feature by displaying the message below.
When cutting at the limits like this, using Centerline will give you the largest possible shape that can be cut out on the WAZER. For example. with a 18“x12” rectangle using Centerline will have the kerf straddle the design lines, resulting in 1/2 kerf width being removed from all sides of the rectangle. This is the largest size rectangle that can be cut with the WAZER.
This means that the Maximum Outside Dimensions for the largest rectangle that can be cut are 17.956”x11.956” (assuming a kerf of 0.044”).
This also means that the Maximum Inside Dimensions for a rectangular hole are 18.044" x 12.044" (assuming a kerf of 0.044").
[Notice] These dimensions are based on a default kerf size (0.044") and will change depending on the material and thickness being cut. As a general specification, the greatest size that can be cut on the WAZER is (18" - 1 kerf width) x (12" - 1 kerf width).
