Job Setup Parameters
Display Resolution
The display resolution will be the same as the encoder resolution. If the job
tolerance is coarser than the encoder resolution (±0.005 for example), you can
adjust the display resolution so you won’t be tempted to waste time by machining
to a finer resolution. Use the
Z key to cycle through all the possible choices. The
choices available depend upon the resolution of the encoders.
Scale Factor
You can define a scale factor for each axis. The typical scale factor is 1.000, which
means that the displayed dimensions are the actual part dimensions. A scale
factor less than 1 causes the part to be smaller than the print dimensions; a scale
factor greater than 1 causes the part to be larger.
Enter the factor by pressing
Near Zero Warning
Each axis has its own near zero range. You can activate or deactivate the near
zero warning feature by pressing the
Z key. When the warning is activated, you
can enter the range. Refer to page 12.
Tool Offset Definition
To determine the relative tool offsets, you can use either a tool presetter or the
readout’s auto offset feature. Use the
Z key to select which method you plan to
use.
For a scale factor that allows for 3% material shrinkage, use this formula:
