Laserkutting hos Bitraf

Workshop hos Bitraf

How does it work

• • Infrarød laser

  • Opptil 6mm tykkelse for treverk

  • Opptil 30mm tykkelse for foam

  • Siden laseren fokuserer på kort avstand, så kan oversiden og undersiden av produktet bli ørlite forskjellig.

How-to

• 1. Get design
  2. Open InkScape
     1. Save file as .dxf. Check off all checkboxes.
     2. Upload file to your personal BitRaf dropbox folder
  3. Open file from DropBox in AutoLaser
     1. Select each area to burn, and set burn settings:
        

        1. Cut-mode/raster

           1. Kutter rett igjennom

           2. Tregere

        2. Engrave-mode/vector

           1. Brenner bare overflaten

           2. Raskere

        3. Corner power: The machine reduces speed towards corners, to avoid burning slightly out of the corner. Gjerne 10% under work power. For høy får ikke detaljene helt løse (brenner ikke fullt ut)

        4. Work power: Power on lines other than corners. Too high will give visible burns

        5. Carve=vector=emboss

        6. Cut=raster=cutting

        7. Carve accuracy: Length mm from line to line in one direction. Higher number makes visible lines with gaps.

        8. Slope: Gradually or suddenly pausing the laser between points. Affects corner power.

     2. Work preview
     3. Download: doc→ mac
  4. Use U- to lower workbed
  5. Press . to autoset focus distance
  6. Insert material
  7. Move laser pointer to upper left corner og material. This is the the outer boundary of your design.
  8. Set origin
  9. Run Range to verify that the material is big enough
  10. Close cover
  11. Start fume vacuum
  12. Start laser
  13. Observe product to be completed
  14. Open cover
  15. Verify all edges are fully loose
  16. Return laser pointer to base
  17. Turn off fume vacuum
  18. Turn off laser
