This machine is for cutting detailed, two-dimensional geometry into large, flat materials.It’s ideal for making boxes, enclosures, and control panels!
This is much faster than 3D printing.It’s also capable of producing much larger, stronger, cheaper, and more accurate parts.Of course, this comes at the cost of stronger design-for-manufacturing constraints. (Your parts have to be 2D sheets/plates.)Materials
Ask a manager if you would like to cut any materials that don’t appear on either of these lists.
DO NOT CUT ANY UNAPPROVED MATERIALS AS THEY CAN RELEASE TOXIC FUMESPre-Approved
These materials are fine to use.A mystery material that looks like one of these does not count!For example, people often confuse polycarbonate and acrylic.MaterialMinimum ThicknessMaximum ThicknessAcrylic1/16 in1/4 inBamboo1/32 in1/4 inCardboard1/32 in1/4 inMasking Tape1 layer2 layersPaper (Printer)1 sheet (held down)10 sheets (held down)Poster BoardnormalnormalWood (General)1/8 in1/4 inWood (Ply)1/8 in1/8 inBanned

*Maker Case and Make a Box will generate great lase-able boxes for the mechanically challenged.Machine Safety
This is an awesome tool that can hurt people in scary ways.Like most such tools, it’s easy to stay safe by being conscious of the danger and following good habits.Dangers
This section outlines the dangers this machine poses, who is at risk, and the best practices to stay safe.Fire
This machine can set the work piece on fire.This poses a risk to the people in the lab, the machine, and the engineering building.Fires can be avoided by using the approved materials and following the procedures in this SOP.
*Never leave this machine unattended while running!
*Always identify where the fire extinguisher is before using this machine.Lazor Beemz
This machine uses an invisible infra-red (IR) laser for cutting and a visible red laser for targeting.This poses a risk to everyone in the lab.Serious eye damage can be avoided by following the procedures in this SOP.
*The panels and hood should never be opened when the laser is enabled.
*Orange IR laser safety goggles should always be worn when operating this machine.
*These only protect against indirect exposure. They are stored in the shorter red tool box.
*Reflective objects should never be placed in the chamber.
*The laser should only be enabled immediately before making a cut, and disabled immediately after that cut has finished.
*The laser is disabled when this switch is in the downward “0” position. The switch should not glow in this position.
When lasing, the material is heated to extreme temperatures. This produces very bright, broad spectrum light, including ultra-violet light. This poses a risk to people nearby the machine.Eye damage can be avoided by not staring directly at the area being lased.High Voltage
The laser tube uses high voltage.This poses a risk to people maintaining the machine or improperly operating the machine.Burns and heart failure can be avoided by removing the keys from the system when maintenance is performed and by checking that the laser tube is not exposed when in use.Toxicity
This machine can produce harmful smoke and vapors when cutting. This poses a risk to the people in the lab and nearby rooms in the engineering building. Negative health effects can be avoided by following the procedures in this document, avoiding use of materials which create harmful gasses, and properly maintaining the air filter.Immediately report any escaping smoke or strong smells to a manager.Motors
This machine uses computer-controlled motors and does not sense how much force they’re outputting. If someone or something is in its way, it will just plow through. This poses a risk to people operating the machine. Injuries can be avoided by staying clear of the X-Y gantry when it’s in motion.Contingencies
Here are some likely worst-cases and what to do if they happen.Fire
If there is a sustained fire in the chamber:
*Hit the E-Stop button.
*Leave the hood closed.
*Get a manager to help immediately.
*Managers:
*Fetch the fire extinguisher.
*If the fire does not put itself out:
*Disconnect the air compressor. (Don’t just turn it off.)
*Turn off the air filter.
*If the fire still does not go out:
*Open the hood.
*Immediately spray the fire with the fire extinguisher.
*Immediately close the hood.
*Contact campus safety: 503-725-5911.
*They can also be reached via the lab’s landline at 5-4404.
*Evacuate the EPL.
*If the fire is still going:
*Pull the fire alarm.
Note that flammable gasses will occaisonally get stuck within the honeycomb grid under the material being cut.These can create momentary flames under the material.This is especially noticable with acrylic.This is normal and not a concern.Laser Exposure
*Immediately hit the E-Stop button.
*Inform a manager of the incident.
*For exposure to the eyes, seek immediate medical attention. For exposure to the skin, treat it as a burn and seek medical attention if necessary.Electrical Shocks
*Immediately hit the E-Stop button.
*Inform a manager of the incident.
*If you experience any symptoms, seek immediate medical attention. (unconsciousness, confusion, burns, numbness, tingling, paralysis, hearing/vision/speech problems, difficulty breathing, seizures, et cetera)Emissions
If you see smoke building up inside the chamber, smell/see smoke leaving the chamber, or notice a strong chemical smell:
*Pause your job.
*Disable the laser, using the “Laser” switch on the right.
*Wait for the smoke/vapors to be filtered out. This can take a few minutes. Do not open the hood during this time.
*Ask a manager to verify that the air filter system is working.Crashes
If the cutting head or the gantry crash into anything, immediately hit the E-Stop button and get a manager.Caught Limbs, Fingers, or HairJq Laser 1390 Printer
Immediately hit the E-Stop button if someone’s limbs, fingers, or hair are caught by the X-Y gantry.When the motors are unpowered, they can be moved easily.
Here are the basics of operating this machine.Cut Geometry
This laser cutter will work with vector files, like DXF, for cutting, engraving, and rastering. Images, like JPG and PNG, can only be rastered.Exporting Your Geometry
You want a DXF that’s in units of millimeters.Quick and Easy Box
If you just need a box/enclosure:
*Go to Maker Case.
*Choose your desired dimensions.
*Select finger style joining.
*If you want a tight/friction fit, select 0.010 inch kerf.
*This can be fine-tuned to your material, but 0.010” is probably fine.
*Download a DXF.SolidWorks
*Open the part you wish to cut
*Change the measurement system to ’mmgs’ (bottom right corner) and ensure your part has the correct dimensions in millimeters. (25.4 mm/inch)
*The main reason for bad DXF files from SolidWorks is using a different measurement system such as IPS(Inch, pound, second) or MKS(Meter, kilogram, second). Use your desired system to design the part but switch to mmgs afterwards to create the DXF file.
*Right click the desired face you wish to create a pattern from and select “export DXF/DWG”
*Complete the following prompts to save the file.Inkscape
*Click File -> Save As.
*Set the file type to Desktop Cutting Plotter (AutoCAD DXF R14) (*.dxf).
*Click Save.
*Set the export parameters. Depending on your version of Inkscape, you may get slightly different menu options here.
*Set the base units to mm.
*Uncheck use ROBO-Master type of spline output*.
*Uncheck use LWPOLYLINE type of line output*.
**These instructions should be confirmed through testing, as they’re from Joe’s memory.
*If you have geometry on hidden layers that you don’t want to cut, you’ll need to select Visible only in Layer export selection.
*Click Ok.Importing Your Geometry
*Login to the computer next to the laser cutter.
*Open RDWorks.
*Import the file you wish to work with.
*Click File -> Import
*You can import most vector files and images, but a safe bet is to use DXF vector files.
*Check your geometry.
*Check that the paths are the correct shape. If they aren’t, you have a couple options:
*Go back to your CAD program and select a different “spline type” and/or “line type” when exporting.
*If you can’t change the spline and line types, you can manually edit the nodes in RDWorks.
This is tricky and you’ll likely end up with some not-quite-right geometry.
*
Check that the bounding boxes of the paths are correct.
*Select a path and check the width and height in the upper left corner.
The X and Y values are not what you want. Those are just the position of the path.
*Note that RDWorks displays this information in units of millimeters, not inches. (1 in = 25.4 mm)
*If the paths are the wrong size, go back to your CAD program and change the units to millimeters.
Alternatively, you can fix this on the fly by scaling the offending paths by a factor of 25.4.Pre-Job Checklist
*Check the top of this page or the main EPL page to see if this machine is “down” or “having issues”.
*If the machine is down, you may not use it!
*If it’s having issues, ask a manager what they are. You may be able to get more details on the machine’s maintenance log at the top of this page.
*Double check with a manager that the laser, filter, and chiller are all okay to use.
*Check that your material is on the approved materials list and not the banned materials list.
*If it’s not on either list, ask a manager.
*Identify where the fire extinguisher is.
*Collect orange IR laser safety goggles for everyone who will be operating or monitoring the machine.
*Make sure there isn’t excessive debris in the tray under the chamber.
*Danger: make sure the laser is disabled before checking the tray!
*Make sure none of the side or rear maintenace panels are open.
*If they are, ask a manager if it’s okay to close them.
*The panels may not remain open when the laser is enabled!Power and Speed Settings
Image files (.jpg, .png, etc.) will always raster, meaning it will not cut. It will just etch the image onto the material. If you want to cut, you need to add vector curves.These can be imported from other software or added directly in RDWorks.
Different materials and thicknesses will require different laser powers or speeds to cut through the material.
In the upper right hand corner of RDWorks you should see a small window that will probably have a single black block followed by cut and speed settings. It is possible to use different cuts and speeds for different parts of your job by using different “colors” to identify different layers on your piece.
*
Click on the vector you wish to edit the cut settings for.
*Click on one of the colors at the bottom of the software to change it. The shape should change to that color and a new color and item should appear in your layer window in the upper right hand window.
*Note that the color only identifies the layer of the vector. Any vector you change to this color will have those cut settings.
*Double click on the layer you wish to edit in the upper right-hand window.
*In the dialog box that pops up, edit the speed of laser to your desired settings.
*Edit the minimum and maximum power of the laser to your desired settings.
*Usually you will just make the minimum and the maximum the same.
*Sometimes it gives you the option to change two power settings. Just uncheck one of them.
*You can change the cut type from cut (will just use the laser to etch the lines on your vector) to scan (will use the laser to ‘fill’ in your vector shape–usually used to etch opaque shapes)
*Note: Scanning large images can take a very long time as opposed to cutting. If you can cut instead of scan, please do so. Also make sure you are using much lower power settings and higher speed settings for scanning.
Alternatively, if you just want to use the same cut settings throughout your job, just change the single black layer that is there by default and directly edit the settings there.
You may need to develop your own cut settings for your material.See the Test Cuts section for more information.It’s strongly recommended that you perform test cuts before running your job!Determining Settings
It’s strongly recommended that you perform some test cuts to ensure you’ll get usable, desirable results.See the Test Cuts section for more information.Usually, three to six small circles are all that’s needed to find acceptable settings.You shouldn’t need to do large arrays of test cuts like the examples below.Below you can find some examples of cuts made in common materials.1/16” Clear Acrylic1/16” BambooPhysical Prep
Q shops keurmerk. When your job is ready in RDWorks:
*Ensure the laser is disabled by turning the switch on the right of the machine off.
*Open the hood.
*Place your material under the laser head.Position Your Work
The green square in RDWorks corresponds to wherever the cut head is when you start your job.
This means that the laser-bed-sized page in RDWorks does not correspond to where your cuts will occur!
The green square is all that maters. It will usually be positioned to the upper left of your piece. So, you usually want to place the upper left of your material directly below wherever the cut head is.
It’s strongly recommended that you also preview your job before running it.Adjust the Focus
*Place the focusing tool on your material.
*Loosen the top knurled ring.
*Slide the lens assembly to rest on top of the focusing tool.
*Gently tighten the top knurled ring to secure the lens assembly.
*Do not over-tighten the focusing knob!
*Remove the focusing tool from the bed.Jq Laser 1390Turn Everything On
However, do not enable the laser yet!Chiller On
*Turn on the water chiller to the right of the laser.
This step is important so the laser doesn’t overheat!
*It may sound an alarm for a few seconds but it should go away quickly.
Controller On
*Turn the key on the top of the laser to the on position.
Filter On
*Turn on the air filter fans via the power strip to the right of the machine.
*Ensure the air hose to the filter is connected to the port on the far right of the machine.Air On
*Then turn on the green air compressor to the right of the machine by pushing the red switch into the down position.
*Air should be flowing out of the laser head continuously at this point. If it is not, check that the handle on the valve is zip-tied into the on position.
*The air pressure in the line should be around 10 psi. Adjust the pressure using the knob to the right of the switch and read the pressure off of the right gauge.
*Double check that a gentle stream of air is leaving the end of the lens assembly.
*If it isn’t, make sure the valve on the blue air line leading to the laser is open.

*Right click the desired face you wish to create a pattern from and select “export DXF/DWG”
*Complete the following prompts to save the file.Inkscape
*Click File -> Save As.
*Set the file type to Desktop Cutting Plotter (AutoCAD DXF R14) (*.dxf).
*Click Save.
*Set the export parameters. Depending on your version of Inkscape, you may get slightly different menu options here.
*Set the base units to mm.
*Uncheck use ROBO-Master type of spline output*.
*Uncheck use LWPOLYLINE type of line output*.
**These instructions should be confirmed through testing, as they’re from Joe’s memory.
*If you have geometry on hidden layers that you don’t want to cut, you’ll need to select Visible only in Layer export selection.
*Click Ok.Importing Your Geometry
*Login to the computer next to the laser cutter.
*Open RDWorks.
*Import the file you wish to work with.
*Click File -> Import
*You can import most vector files and images, but a safe bet is to use DXF vector files.
*Check your geometry.
*Check that the paths are the correct shape. If they aren’t, you have a couple options:
*Go back to your CAD program and select a different “spline type” and/or “line type” when exporting.
*If you can’t change the spline and line types, you can manually edit the nodes in RDWorks.
This is tricky and you’ll likely end up with some not-quite-right geometry.
*
Check that the bounding boxes of the paths are correct.
*Select a path and check the width and height in the upper left corner.
The X and Y values are not what you want. Those are just the position of the path.
*Note that RDWorks displays this information in units of millimeters, not inches. (1 in = 25.4 mm)
*If the paths are the wrong size, go back to your CAD program and change the units to millimeters.
Alternatively, you can fix this on the fly by scaling the offending paths by a factor of 25.4.Pre-Job Checklist
*Check the top of this page or the main EPL page to see if this machine is “down” or “having issues”.
*If the machine is down, you may not use it!
*If it’s having issues, ask a manager what they are. You may be able to get more details on the machine’s maintenance log at the top of this page.
*Double check with a manager that the laser, filter, and chiller are all okay to use.
*Check that your material is on the approved materials list and not the banned materials list.
*If it’s not on either list, ask a manager.
*Identify where the fire extinguisher is.
*Collect orange IR laser safety goggles for everyone who will be operating or monitoring the machine.
*Make sure there isn’t excessive debris in the tray under the chamber.
*Danger: make sure the laser is disabled before checking the tray!
*Make sure none of the side or rear maintenace panels are open.
*If they are, ask a manager if it’s okay to close them.
*The panels may not remain open when the laser is enabled!Power and Speed Settings
Image files (.jpg, .png, etc.) will always raster, meaning it will not cut. It will just etch the image onto the material. If you want to cut, you need to add vector curves.These can be imported from other software or added directly in RDWorks.
Different materials and thicknesses will require different laser powers or speeds to cut through the material.
In the upper right hand corner of RDWorks you should see a small window that will probably have a single black block followed by cut and speed settings. It is possible to use different cuts and speeds for different parts of your job by using different “colors” to identify different layers on your piece.
*
Click on the vector you wish to edit the cut settings for.
*Click on one of the colors at the bottom of the software to change it. The shape should change to that color and a new color and item should appear in your layer window in the upper right hand window.
*Note that the color only identifies the layer of the vector. Any vector you change to this color will have those cut settings.
*Double click on the layer you wish to edit in the upper right-hand window.
*In the dialog box that pops up, edit the speed of laser to your desired settings.
*Edit the minimum and maximum power of the laser to your desired settings.
*Usually you will just make the minimum and the maximum the same.
*Sometimes it gives you the option to change two power settings. Just uncheck one of them.
*You can change the cut type from cut (will just use the laser to etch the lines on your vector) to scan (will use the laser to ‘fill’ in your vector shape–usually used to etch opaque shapes)
*Note: Scanning large images can take a very long time as opposed to cutting. If you can cut instead of scan, please do so. Also make sure you are using much lower power settings and higher speed settings for scanning.
Alternatively, if you just want to use the same cut settings throughout your job, just change the single black layer that is there by default and directly edit the settings there.
You may need to develop your own cut settings for your material.See the Test Cuts section for more information.It’s strongly recommended that you perform test cuts before running your job!Determining Settings
It’s strongly recommended that you perform some test cuts to ensure you’ll get usable, desirable results.See the Test Cuts section for more information.Usually, three to six small circles are all that’s needed to find acceptable settings.You shouldn’t need to do large arrays of test cuts like the examples below.Below you can find some examples of cuts made in common materials.1/16” Clear Acrylic1/16” BambooPhysical Prep
Q shops keurmerk. When your job is ready in RDWorks:
*Ensure the laser is disabled by turning the switch on the right of the machine off.
*Open the hood.
*Place your material under the laser head.Position Your Work
The green square in RDWorks corresponds to wherever the cut head is when you start your job.
This means that the laser-bed-sized page in RDWorks does not correspond to where your cuts will occur!
The green square is all that maters. It will usually be positioned to the upper left of your piece. So, you usually want to place the upper left of your material directly below wherever the cut head is.
It’s strongly recommended that you also preview your job before running it.Adjust the Focus
*Place the focusing tool on your material.
*Loosen the top knurled ring.
*Slide the lens assembly to rest on top of the focusing tool.
*Gently tighten the top knurled ring to secure the lens assembly.
*Do not over-tighten the focusing knob!
*Remove the focusing tool from the bed.Jq Laser 1390Turn Everything On
However, do not enable the laser yet!Chiller On
*Turn on the water chiller to the right of the laser.
This step is important so the laser doesn’t overheat!
*It may sound an alarm for a few seconds but it should go away quickly.
Controller On
*Turn the key on the top of the laser to the on position.
Filter On
*Turn on the air filter fans via the power strip to the right of the machine.
*Ensure the air hose to the filter is connected to the port on the far right of the machine.Air On
*Then turn on the green air compressor to the right of the machine by pushing the red switch into the down position.
*Air should be flowing out of the laser head continuously at this point. If it is not, check that the handle on the valve is zip-tied into the on position.
*The air pressure in the line should be around 10 psi. Adjust the pressure using the knob to the right of the switch and read the pressure off of the right gauge.
*Double check that a gentle stream of air is leaving the end of the lens assembly.
*If it isn’t, make sure the valve on the blue air line leading to the laser is open.
