Hello all,
I have an f1 ultra that is almost straight out of the box.  I have used it a few times to do anodized business cards and a few black dog tags.  The fiber laser works well for that as far as removing the coating.  It however doesn’t do any engraving in the metal.  I have calibrated it till I’m blue in the face, cleaned the lens several times, and been in contact with customer support.  I am rolling into week 2 of laser issues and wonder if anyone else has any similar issues.  I have also done the focus shift as well, it barely touches this.  So I have tried manually offsetting this by having a stack of material about 10mm off the deck and auto sensed the height.  From there I have gone 8mm plus or minus the height of the material to see if it makes a difference in cutting.  The photos attached are brass and copper material doing the focus shift.  When the laser is on barely any light is seen just hear the fan.  I have seen other fiber lasers work and they make noise when the material is being worked. Been in contact with customer support, however it’s slow going due to the time difference.  Nothing has been working.  Power for fiber ir is at 100% tried score, engrave, emboss, nothing is working.  Gone from speed being anywhere from 2, 40, 80, 100, 200, 300 with no change to the material.  Just seeing if anyone else has seen this issue or not, it only looks like it is removing dirt off the surface of the material.  Any help would be greatly appreciated.
