Epilog Fusion M2 40 Laser Engraver

...

• The Epilog Laser Engraver/Cutter uses line weight in the drawing sent to it to determine how to interpret those elementswhether or not it will be engraving or cutting a given shape.  A vector operation is a cut, and a raster operation is going to engrave the image onto the material in the machine.  If the line weight is equal to 0.001 points, it will be interpreted as a vector cut, and if it 's is greater than that 0.001 points in weight (thickness) then it will be interpreted as a raster.
• The laser kerf is 0.004 "inches or .1016 mm.
• Cutting/engraving order: Generally the machine etches engraves first, then cuts.  Almost always cuts inside before outside   It will almost always cut the interior shapes before cutting the outside profile (Not true with letter outline or scanned images converted to vector).
• Color mapping can be used for different depths of engraving, but you need to define the colors/depths in the RGB color space, and they must perfectly match the RGB values in the image softwareEpilog Print Driver.  For help with this, please consult one of the Academic Makerspace Technologists.

Machine Process

1. Start up

   1. Turn on computer and laser

   2. Turn on blower exhast and compressor

   3. Clean lens (see this process is performed periodically by Makerspace technicians. See details below.)

   4. Set material to be engraved/cut onto cut bed grid and push material to the back left corner against the rulers

   5. Set manual focus depth

   6. Close cover of engraver

2. Set up Image to print

   1. Standard is Adobe Illustrator (see below)

3. On the Epilog Device

   Set manual focus depth, if not set to AutoFocus

   1. Scroll through setting settings on keypad → Find job and start. The most recent job should appear first.

   2. Watch job complete, to make sure it doesn’t catch fireAlways , always watch the laser.

   3. DO NOT LEAVE LASER UNATTENDED

      If on fire → blow out flame (DO NOT LEAVE LASER UNATTENDED)hit emergency stop button. Open the cover and push the gantry out of the way. Use the provided fire blanket to smother the flame. Check that the flame has been completely neutralized before removing the fire blanket or material. If the flame is too large to smother with the fire blanket, pull the pin from the fire extinguisher next to the machine, squeeze the trigger, and spray in a right to left motion at the base of the flame. 

   4. You can stop and remove media, but there will be no good registration for continuing the part if you do.

   5. Always watch the laser while in operation!!

   6. If a cut fails to completely penetrate the material, leave the material in place, and if safe to do so, the job can be run a second time over the same paths.

4. Shut down

   1. Make sure nothing is still burning or generating fumes
   2. Turn off
blower
5. 1. exhaust, laser cutter, and compressor
6. Turn off lasercutter
7. 1. Clean out the cut bed grid of spare parts, if needed, using the provided vacuum

Software:

• The primary software used to print directly from the Makerspace computers is Illustrator. Please ensure that your line weight is always set to .001 for cutting.
• AutoCAD - select a window
• SolidWorks: from drawing sheet, 1:1 scale, need to figure out line weightsSuggest using Adobe Illustrator for vector - but set line weight to .001 points for anything that needs to be cut.
• Can use anything for raster (eg. Photoshop)

...

• Process: File → Print → Epilog → Setup → Preferences (this is the dashboard)
• Cut ⇒ set stroke width to 0.001 points for cutting as a vector operation
• Engrave ⇒ Anything above 0.001 point (raster operation)

Options to set in Preferences (Dashboard)

• Resolution: default is 600.  Max is 1200.  Go lower for faster etching.  Doesn't affect cutting.
• Autofocus on (and set material thickness size) or turn autofocus off and set grid up/down height with jog functions and jig.  Autofocus is not really autofocus since you have to manually put in the thickness
• Manual focus → place registration tool on focus head, then click focus on panel, then use the joystick to adjust the height of the table.
• If the material varies in height, jog to desired location and then focus.  Don't save anything → just uncheck autofocus and don't change stage height
• Reset → sends head back to home location without changing the height
• Center engraving → not used often. Sets a new home position. And that position is set by eye (manually).
• Pick raster/vector (cut) or both.  E.g. If you have both types in the file and set it to raster it will ignore the cut lines (stroke weight < 0.001pt)
• Make your Illustrator Artboard/paper drawing size the same as your stock size, and then make the size in preferences the same too.
• There are separate laser settings for both raster and vector
• Look in the manual for setting guidelines, but note that you may have to interpolate or guess, if the material or thickness is not covered explicitly
• Balance speed and power - Its useful to experiment with new materials/thicknesses to get best balance of cutting/burning
• Cutting small areas → head won't get to full speed in full areas.  10% speed per inch of width
• Engrave direction - generally starts at the back of the machine and works forwards ⇒ not often changed.
• May want to reverse to avoid soot from covering freshly etched surface
• Image dithering ⇒ not often changed.  May want to adjust for images or photos
  • “Jarvis” setting may work better with photos
• Speed Comp ⇒ Reduces speed by ½
• Power Comp ⇒ Reduces speed when rounding corners with cutting
• Sometimes a faster setting with multiple passes will work better because it doesn't burn as much. Higher power can lead to flame  

...

Raster: variable depth control (Color mapping)

• Use RGB color mode (File → New → Color map RGB)
• Set color → laser cutting values in
• Print → Setup → Preferences → Color mapping

Loading presets for different materials (Advanced tab)

• • Print → Setup → Preferences → Advanced
  • Save and load preset settings for laser and piece size
  • Can dowload presets from Epilog
