How does it work

• • Infrarød laser

  • Opptil 6mm tykkelse for treverk

    • 4mm for blå laser

  • Opptil 30mm tykkelse for foam

    • 4mm for blå laser

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

How-to

• 1. Prepare design file
     1. Get design
     2. Open file in InkScape
        1. Select everything and click Path → "save object to path" and "save track stroke to path" or something.
        2. Save file as .dxf. Check off all checkboxes.
        3. Upload file to your personal BitRaf dropbox folder
     3. Open file in Autolaser
        1. In the Work tap to the upper left, check that Com6 is entered. If not, you will get the "Link error" message, and must click "Search" to fix it.
        2. 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.

        3. Work preview
        4. Download: doc→ mac
  2. Prepare laser
     1. Turn on laser
     2. Use U- to lower workbed
     3. Press . to autoset focus distance
     4. Verify your material has an even depth all over, or the cutting will be uneven.
     5. Insert material
     6. Move laser pointer to upper left corner og material. This is the the outer boundary of your design.
     7. Set origin
     8. Run Range to verify that the material is big enough
     9. Close cover
     10. Start fume vacuum
  3. Use laser
     1. Start laser
     2. Observe product to be completed
     3. Open cover
     4. Verify all edges are fully loose
     5. Return laser pointer to base
     6. Turn off fume vacuum
     7. Turn off laser

Materialer

Finn riktige settings på nye materialer:

• "...så justerer du opp eller ned avhengig av om du kommer igjennom eller ikke.
  Legg materialet på ei treplate, så er det enkelt å få fokus riktig. Og hvor dypt i treplate man kommer er god indikasjon på hvor mye ekstra energi man har til overs"
  - Jon
• "Sålenge man ikke har makset på fart, øk farten.
  Maks praktisk fart er kanskje rundt 40 mm/sek, muligens høyere om man kan tolerere litt ujevnheter i brå svinger."
  - Jon
