The plotting process
The enVision plotter uses a knife installed in the tool head to cut shapes in the
material (usually vinyl). After the job is cut, you remove the excess material
(called weeding the job) from the design. Cutting accuracy and weeding ease
depend on matching the tool settings to the material being cut. Tool settings are:
„
force
„
corners
„
speed
„
acceleration
Tool setting tips are described in the following paragraphs.
Tool settings
The four tool settings
−
force, corners, speed, and acceleration
−
must be
matched to the material being cut. In the back of this manual is a card with
recommended tool settings for various materials. These tool settings are starting-
point guidelines. Quality cutting is dependent on the job being cut. For example,
if a job has many long, straight lines, you can cut at increased speed and
acceleration. If a job has many corners and curves, you may want to use less
speed and acceleration. In general, the best possible cut quality is achieved by
using the minimum tool force that provides easy weeding.
Also note that occasional adjustments need to be made to tool settings based on
blade wear. Changing settings up or down do not mean that there is a problem
with the plotter. For example, blade wear may require changing the settings to
maintain optimum cutting quality. Other factors, such as temperature or
humidity changes or cutting small text, may also require changing the tool
settings.
Material selection
The plotter firmware contains a table of materials (called rule sets) with
corresponding tool settings for cutting Gerber materials. When you select the
material you plan to cut in the plotter Settings Menu, you automatically set the
factory default tool settings for that material. A rule sets guide chart is provided
on reference cards in the back of this manual.
Note: There are additional rule sets built into and available in the GA plot
program as described in the following paragraph.
For more information on setting and changing the rule set values, refer to the
section "Choosing Tool Settings" on page 28.
