laser cutting acryl

lazzzor soup → lazzzor.soup.io

We have a Epilog Legend 36EXT Lasercutter (60 W-Version)!

2D figures can be cut out of a wide range of materials (wood, many plastics, paper, ..) but metals can only be engraved. The laser is focused on a very very small point so the cut itself is smaller than 1/10 mm. To get an idea what you can do with it, visit Lazzzor Blog or Bre Pettis or look further down for some links.

Do you want to cut?

If you want to cut or engrave something, get in touch with one of our friendly helpers. If it's really important though, contact us under .

• Polycarbonat (PC), can't be cut well with heat, stinks,
• MDF, glew makes the lenses dirty really fast

Cheats

• Focus:
  • Press Stop and then Focus on the machine: Focus on the homeposition, rather then 50 mm diagonally shifted from home..
  • XY-Off, Go: Free moving mode. OK thats not a cheat. NOW: keyboard cursor up/down moves the table up down. Cool! Also works after pressing "focus", without "go" afterwards..
  • Autofocus happens at the first cut/engrave position of the file.
• Engrave:
  • "bottom up" is sometimes better, depends on the direction of the fumes. Fumes should move away from the deep parts.
  • Stucki Rastering is nice.. Brighten=different gamma
  • panel 3d mode: Not the position of the laser pulses is rastered, but instead the laser-power changes by the gray level. So the laser seems to be constantly on. Needs more Laserpower than in the tables (+30%?).
  • Engrave speed and Power can be changed while the job is lazzoring. Not possible for vector! Press spee/powerd, and cursor up or down, go to apply
  • Plastic: Engrave whith cover foil removed.
  • Plastic: engrave 1.5 mm out of focus=smoother surfaces.
  • Plastic: second pass with low power settings: removes dirt from the depths.
  • Plastic: can be wetted for less melting..
  • Anodizes Aluminium: LOW POWER, High Speed, maybe multiple passes are recommended in the manual.
  • Glas: Coat Area with dish soap. Afterwards, polish with scotchbrite
  • Delrin: super for 3d engrave
  • Colorized Depths: Apply Wax to the top,engrave, color, sand top.

• Homeing:
  • Center Engrave option in the driver-panel: where home is, e.g. move home from left top to center point, so you can engrave text on the center of a circle...
• General
  • Multiple passes=print tab->number of copies...
  • The rulers can be flipped to take out the hexahedral baseplate.
