JobControl Outline Function

Positioning engraving, cutting, and marking jobs correctly is critical to guarantee perfect results, especially when engraving intricate layouts on expensive or irregular shape materials.

Luckily, Trotec’s JobControl’s “Job Outline Function” supports both experienced laser and novice users by allowing you to check the correct position prior to starting the engraving job. This feature ensures the job is positioned correctly every time, which prevents faulty engraving and saves you both time and money!

How it works:

  1. Send the job from your graphics software to the JobControl software.
  2. Position the material in the laser.
  3. Position the job on the JobControl plate.
  4. Select Edit, Outline job(s).
  5. Watch as the lens carriage begins outlining the shape of the selected job(s). With the laser switched off, the red dot pointer will indicate the outline area of engraving, cutting, and/or marking job.
  6. The red dot pointer travels along the effective outline, not along the biggest rectangle.
  7. The laser will continue to outline the job until this action is cancelled. This will give you the opportunity to either move the job to another position on the plate or move the object to be engraved.
  8. Once you have everything positioned correctly, cancel the job outline function and start engraving.

Tips & Tricks: Positioning Jobs Multiple Times in JobControl

Trotec’s unique JobControl Software offers multiple features that provide functionality, productivity, flexibility, and reliability to the engraving, cutting, and marking process!

Today, we are going to highlight the different options available to position multiple jobs, including “Position Jobs Multiple”, “2 Plates Together”, and “Duplicate Job” and how you can use these features as an aid for laser processing.

This feature is especially beneficial when a material needs to be engraved multiple times with the same design.

Position Job Multiple:

When selecting a job in the job queue, instead of double clicking (sends job to top right of plate) or dragging (allows you to freely position job on plate), right click on the job and select “Position Job Multiple”.

When the “Multiple Placement” window opens, indicate how many times you would like the selected job to be duplicated. Once you’ve selected “OK” JobControl will automatically position the indicted number of jobs on the plate.

Optimized Sheet Utilization – 2 Plates Together:

If you position two sheets of material side by side in your laser, you can effectively process a job multiple times on two pieces of material while facilitating the “position job multiple” feature.

Open “Plate Setup”; located under “Plate” on the top tool bar. When the “Plate Setup” window opens, check “2 Plates Together” at the bottom of the window and select “OK”.

Repeat the steps for “Position Jobs Multiple”

 Duplicate Job:

If you have two identical jobs to be processed, you can (1) follow the steps above for “position job multiple” or (2) duplicate the job.

If you choose to duplicate the job, first position the job on the plate. Once you have the job positioned on the plate, right click on the job and select “duplicate job”. Job control will automatically provide a carbon copy of the job next to the already positioned job.

Job Control Tip:

The standard value for the plate setup in JobControl is equivalent to the maximum engraving area of the Trotec laser you are using (i.e. Speedy 300: 28 in x 18 in).

If you want to use the multiple positioning command on a smaller work piece, try adapting the plate set up value in JobControl to reflect the actual area of the work piece.

Reverse Engraving

Trotec’s unique JobControl Software offers multiple features that provide functionality, productivity, flexibility, and reliability to the engraving, cutting, and marking process!

Today, we are going to highlight reverse engraving.

Generally while processing, the laser starts at the top left corner and ends at the bottom of the engraving job. For some applications and materials, however, it can be helpful to start from the bottom.

Dust and fumes are removed via the rear of the engraving cabinet. This means that the removed material is drawn over the engraved area. Using the reverse engraving means that the dust is drawn over the intact material. Consequently the cleaning process is easier. Reverse engraving is mainly used for engraving of laminates (plastics) and wood

Level-up Your Power!

How to choose the proper power level is one of the main questions asked when a customer is considering a CO2 laser. Typically, the wattage availability of C02 laser systems spans from 12 watts all the way up to 400 watts. More often than not, a higher wattage can decrease your production time. The amount of power needed is dependent on the type of material and how you would like to process it. There are three processes that are impacted by power: engraving, marking, and cutting.

Materials can essentially be categorized into two categories, hard and soft. On average, the materials that engrave well with lower wattages are softer materials such as plastics, fabrics, and paper. For harder materials such as cast acrylics, wood, and glass a higher power level is preferred. Engraving is subjective based on the perspective of each individual. For example, what I find to be engraved too deep you may see it as not deep enough; therefore, determining your “desired look” is extremely important in choosing the proper power level.

The most common materials used in marking with a CO2 laser are: anodized aluminum, coated metals, ceramics, stainless steel, and other bare metals. With coated metals, ceramics, and anodized aluminum, a lower wattage can often be effective; however, take note of the time involved. For stainless steel and other bare metals, a laser bonding material is required to achieve a high contrast mark on the metal. This laserable material is bonded to the substrate through the energy of the laser. This bonding process requires higher power levels for the bonding to successfully occur. If the power is too low, the solution will simply wipe away.

Selecting the appropriate laser power is important in achieving quality cutting results and optimal processing times. With cutting, selecting the proper power level will be based on the type and thickness of the material in addition to the desired quality.

For Example:

Cutting through 1/8” and 1/4” materials can generally be achieved with a lower wattage; however, because of the laser power’s reaction to the material, you may not achieve the same edge quality as you would with a higher powered laser.

If you needed to cut through 1” acrylic and achieve flame polished edges we would recommend a high powered laser; however, if it were paper or fabric, a lower wattage laser would easily achieve your desired results.

The type and thickness of a material, desired output and quality, how the material is processed, and application requirements all play a huge role in selecting the wattage of your laser system. In addition, considering which materials you are processing now along with materials you plan on process in years to come, guarantees the chosen power level will meet all of your company’s growing needs.

Another important factor is to understand your material and have it tested by myself or one of our application engineers before you determine what wattage you would like. A demonstration on the laser system or sending your materials in for processing will leave you feeling confident that you have chosen the best laser for your application needs.

Keep your laser healthy and running marathons!

To maintain the health of your laser, guaranteeing top performance and speed, follow this bi-monthly maintenance checklist.

Lens Cleaner1) Check and clean all optics in the beam path.

2) Check your beam alignment.

3) Clean power supplies on rear and/or bottom of laser with compressed air.

4) Blow out cooling fins and fans on air cooled laser tubes with compressed air.

5) Inspect and clean Z axis spindles. Using WD40 clean and lubricate z axis. Wipe off any excess WD40.

6) Clean Plexiglas top with mild soap and water. Do not use alcohol.

7) Clean inside of machine and circuit boards with compressed air.

8) Any time you use compressed air on your machine, check and clean optics for dust and debris.

Clean your lens!

LensKeeping your lens clean is critical as a dirty lens can result in poor marking and engraving capabilities.

You should check your lens at least once a week to ensure it’s clean. If you are working with rubber or wood, it’s recommended to check it daily.

Only clean the lens if it is dirty, as excessive cleaning can shorten the life of the lens.

The oils in your skin will damage the lens coating so never handle the lens with your bare fingers.

Always use a proper lens wipe or cotton swab with industrial optic cleaning fluid. Cleaning fluid from a camera store or eyeglass shop will contain water which will harm the lens coating.

Important: Special care should be taken when cleaning a broken lens. The coating is very poisonous when broken, so it should always be handled and disposed of in a responsible manner.
