Cut 3/16 Luan on the FLC1490_Laser_Cutter.
- Speed 5, power 100% cuts almost everything except for a few stubborn patches of filler/glue, but those can be finished with a knife.
- Cutting all the way through the piece in the first pass allows the smoke to be sucked from the bottom, decreasing the smoke in the laser cutter greatly.
- If you're lasering larger piece (>12") it might be useful to do the fine details in a first-pass layer, and then the overall outline as a last layer as board might curl up slightly after a large section is cut loose.
- When focused the FLC1490 can cut beams as thin as 0.05" but the 0.02" beams just got burnt. When the focus was a bit off the 0.05" beams were burnt.
- The 0.05" beams burn down to 0.045-0.035" and are too thin for structural support, but make nice internal members.
- Making interlocking joints on an outside-corner without compensating for the removed material fit well side-to-side, but the tongues might be a bit short. Trying to do the same thing for tendons that fit into a rectangular hole is a bit tight, but nothing a bit of filing can't fix.
- Exporting from Draftsight to R2000-2002 ACSII Drawing (*.dxf) carries across the scale in inches just fine.
- Make sure to explode text to a series of lines before exporting.
Making combined raster and vector cuts
- Make an outline layer to align the raster and vector boundaries
- Enable only raster layers and print
- Make sure your DPI is set high enough
- Check "Ignore Raster" in FSL
- Enable only vector layers and print
- In FSL start job from Raster Tab
- Make sure DPI is set high enough
Cutting 1/16" taskboard
- Speed 60%, power 100% for a through vector cut
- Speed 50%, power 50%? for a vector decoration
- Speed 50%, power 75-100% for brick engraving (pending painting tests)
- vector cuts 0.04" across are unreliable. Probably possible with clever layer ordering
Cut 3/16" Luan and 1/4" birch ply on the FLC1490_Laser_Cutter
- Even at speed 20 and 100% power some attempted kerfs cut all the way through
- Speed 6 (100% power) might be an underestimation of the cutting power
- Trying to cut perfectly to the edges of a sheet (2'x4' design on a 2'x4' board) doesn't work. You'll never get it aligned to an adequate tolerance\
- When doing a large cookie-cutter construction, give some slop room on the supports for the top moving slightly
