It’s no secret that the vinyl cutter/plotter is the
workhorse of the sign making industry.
Ever since the first CAD Cutting Plotter was introduced by Gerber in
1982, people have been finding creative new ways to put these machines to
use. The versatility of these simple
machines is amazing. Our customers use
them for making decals, lettering vehicles, cutting paint mask and sandblast
stencils, all types of outdoor and indoor signage, … the list is endless.
Part of what makes the cutter/plotter such a work horse is
its simplicity. It’s not unusual for
customers to tell me about their 20 year old vinyl cutter that works as well or
better today than the day that they purchased it. There are only a few parts that need to be
maintained and/or occasionally replaced.
If you keep any eye on them and maintain them regularly you can expect
your vinyl cutter/plotter to last a lifetime. Even a those not mechanically inclined can change all of the items listed below (with a little practice) in less than 30 minutes.
The regular replacement parts are:
·
Cutter Protection Strip (CPS):
Perhaps the most abused and misunderstood part of the vinyl cutter.
Usually made from smooth durable rubber or Teflon. The cutter protection
strip protects the blade from damage if the cutting force and depth is set to
high. When left unmaintained or not replaced, the cutter will no longer make
straight, true, clean cuts and may result in very jagged edges.
It’s Time to Replace When: Your
shapes and letters are starting to have jagged edges or unfinished cut paths.
Your cuts are not weeding as easily as they used to, or weeding easier in some areas
vs others. Your CPS has any noticeable lines or
grooves in it.
Time to Replace: 10 –
15 minutes, Difficulty - Moderate
·
Cutting Blade: The cutting blade is typically a thin,
angled, piece of metal, carbide, or steel that cuts through the media creating
the image desired left to be weeded out. It is recommended to replace your
cutter blade every year with moderate to heavy use on standard material.
Sandblast, metalized or reflective film will require a specific, thicker angled
blade which requires a more regular replacement. There is no exact time frame
at which the blade needs replacement and varies per machine but there are a few
things to keep an eye out for.
It’s Time to Replace When: Your
shapes and letters are starting to have jagged edges and weeding around the cut
letters or image is becoming increasingly difficult. You will also notice the
ends of cut paths sometimes are not completed or not cut all the way through
resulting in you having to punch or poke the letter or image downward to
release it from the rest of the material surrounding it.
Time to Replace:
2 minutes, Difficulty - Easy
· Blade Holder: This holds the blade in place when cutting material. It is recommended to replace the blade
holder within a year of moderate to heavy cutting. Most people are unaware that
this is a wearable object under constant movement and needs replacing. Once
worn down, it can degrade cut quality tremendously resulting in what seems to
be near impossible weeding of material. Some machines offer a metal counterpart
which will extend the life of the holder even with everyday use.
It’s Time to Replace When: Your
shapes and letters are starting to have jagged edges and weeding around the cut
letters or image is becoming increasingly difficult. As with the blade and cps,
random paths will be unfinished but more apparent. Weeding material will become
increasingly difficult and sporadic around the cut letters or image. You might also notice a "stitch pattern" on your letters. Curved
edges such as zeros, O’s, and inside of letters or numbers will no longer have
a smooth curve and will resemble that of a stair case or vibrating line.
Time to Replace:
2 minutes, Difficulty - Easy
·
Pinch Rollers: These small rollers that
are to be positioned above the designated grip rollers are what holds onto the
material and progresses it back and forth during cutting. Typically they last
quite a while and can be maintained simply by taking them off and cleaning them
of any dirt, dust, or vinyl scrap stuck to them. They do wear out and need to
be replaced from time to time resulting in straighter tracking of media at longer distances.
It’s Time to Replace When: Your vinyl is not moving back and forth in the cutter in a straight line. You're unable to feed 6 - 10ft of material continuously through your cutter without running off the pinch rollers.
Time to Replace: 5 - 10 minutes, Difficulty - Moderate
These quick fixes will keep your cutter humming and ensure a long and creative life.
