Materials FAQ for LJS wood materials

Note: All settings are taken from using a 60-watt laser, if your laser’s power differs from this please adjust the recommended settings accordingly.

Cutting and Engraving the Materials

Q:What settings are good for cutting the materials?

A:Based on the laser power we recommend:

  • 6% Speed
  • 100% Power

Q:What settings are good for vector engraving?

A:Based on the laser power we recommend:

  • 20% Speed
  • 40% Power

Q:What settings are good for Raster engraving (Photo engraving)?

A:Based on the laser power we recommend:

  • 70-100% Speed
  • 100% Power

Q: How do I find the cutting kerf of my laser for the material?

A: To find your cutting kerf of the laser create a 1″ by 1″ square and cut it out with your preferred laser cutting settings.  Once it has been cut out use a pair of calipers, or other measuring tool, to measure the exact size of the square.  If the square comes out to be 0.997″ then your cutting kerf is 1.0″ – 0.997″ = 0.003″.  Most lasers cut around 0.004″ – 0.006″ but that can waver depending on power settings. Excessive power or slower speed can result in a larger cutting kerf.

Q: When cutting out a LJS project how do I loosen or tighten the fit of the pieces?

A: To easily adjust the fit between the pieces you can easily adjust the cutting kerf settings inside any of the LJS programs.  If you want to have a tighter fit you can easily increase the cutting kerf by 0.001″ – 0.002″.  Likewise for making a project fit a little looser you can decrease the kerf by 0.001″ – 0.002″.

 

 

Cleaning the Materials

Q: What do you use for cleaning the materials after they’ve been cut/engraved?

A: We use a bottle filled with water, and then we add 4 tablespoons of Joy ultra-concentrated dish washing soap. Then just put the cap on the bottle and shake it for 10 seconds and it’s ready to go.

Q: What’s a good method for cleaning the materials after they’ve been cut/engraved?

A: Once the pieces are done it’s good to dampen a clean cloth with the liquid described in the question above.  Then with even and firm pressure wipe away the residue that’s accumulated. In some cases the residue might not come off in some spots, but all that’s required is a few more rubs of the damp cloth on the spot to remove the residue.

Q: I’ve noticed with the lighter materials that after I’ve cleaned them the backside still looks yellowed and sometimes burnt, how can I fix this?

A: This is generally caused by having to much of the laser cutting through the piece and then inevitably burning the backside which can be the result of to much power and/or to slow of a speed.  To resolve this you can easily adjust and fine tune your laser settings to reduce, and in a lot of cases eliminate the back burn on the material.  However another method that we use is to take transfer tape and smoothly and cleanly apply it to the material’s backside.  The tape will absorb the residue and will also take the effect of the back burn so that the material doesn’t. If you don’t happen to have transfer tape though, white printer paper also works great and has similar results.
