Utilizing heavy machinery demands its proper
usage to avoid pitfalls. Whether a novice or an
experienced engineer, it is important to learn
how you can avoid common mistakes while
operating heavy machinery like Laser engraving.
It may harm its sensitive parts as not all the
parts come with a great resistance power except
for Mitsubishi spare parts and Fanuc spare
parts. When issues occur, you might end up just
guessing what went wrong while using it. So, to
help you we have come up with common mistakes
you might be making.

• 1. Using Wrong Fabrics
• Using laser on a fabric which cannot withstand
  with it will end up burning. Research and
  understand which fabrics can combat high power
  settings during the process. Denim, leather,
  canvas can resist high power settings. When you
  use delicate fabrics, set your settings at high
  speed and gradually lower the power to 5-10.
  And to avoid wasting any material, test a small
  piece, in the beginning, to see if the fabric
  can withstand. Adjust the power until you get the
  results.
• While attempting direct-to-garment engraving,
  lower the DPI (dots per inch). Engraving at a
  lower DPI will ensure the laser vaporizes the
  top layer and doesnt burn entirely through the
  fabric. General engravings work best at 150 to
  300 DPI.
• Using the Wrong Acrylic
• There are two types of acrylic used in laser
  engraving.
• Liquid Acrylic
• Extruded Acrylic
• Liquid acrylic is best when producing cast
  acrylic sheets and objects. You pour it into the
  molds to set into various shapes and sizes. It
  is the perfect type of acrylic for engraving as
  it turns frosty white color while engraving. It
  wont give your projects flame-polished edges on
  cutting it with the laser.

• Another type of acrylic used for engraving is
  Extruded acrylic. A machine turns extruded
  acrylic in sheet format. And because of the
  high-volume manufacturing technique, it is less
  expensive. It cuts clean with smooth outputs and
  produces a flame-polished edge. And when used
  for engraving, it provides you with clear
  engraving. So, if you want a frosted white
  finish, do your engraving project with liquid
  acrylic.
• Inconsistent Glass Engraving
• While you are using laser engraving on glass,
  sometimes it does not get through it properly.
  As a result, it fractures the surface.
  Eventually, it will produce the fractured glass
  surface with a frosted appearance. Rough and
  chipped.
• To avoid that and produce a smooth frosted
  finish, here are some tips to help you
• User lower resolution. Up to 300 DPI. As you
  separate the dots you are engraving, it will
  produce better results.
• A DIY tip Apply a thin, wet sheer of newspaper
  or a paper towel to the area to help with the
  heat dissipation. It improves the overall
  process. Make sure the paper you are applying is
  flat and not wrinkled.
• You can also try changing the color black in your
  graphic to 80 percent black.
• Polish the area with a non-scratch scouring pad.

• User better laser parts. Mitsubishi spare parts,
  Fanuc spare parts will increase the efficiency
  of your machine.
• Apply a thin layer of liquid dish soap in the
  area.
• Not Getting Same Results while Wood Engraving
• We see maximum engraving happening on the wood.
  It is one of the most laser-friendly materials
  available out there. As woods have different
  types, they might react differently to laser
  engraving. For example, if you make a large
  square from a piece of cherry, it would have a
  uniform appearance. If the same piece was made
  out of oak, it might vary in height with a
  non-uniform appearance.
• To smoke and debris, try engraving from the
  bottom up.
• Wipe off the surface of the wood with a damp
  cloth when engraving the stained wood.
• Lack of Efficiency in the Engraver
• When it comes to maintenance, it is important to
  clean the machine on a regular base. You get the
  manuals along with your machine. It is also
  important to inspect the optics on a weekly base
  when needed. Notice when your optics look
  smudgy. Because thats when you have to clean
  them.

Conclusion These are the most common mistakes
you could be making. If you are a manufacturer,
designer, or a layman, avoid these mistakes and
increase the efficiency of your laser machine.
