Is it a different cam software that you use or do you just save as a different processor Think it would depend. Fusion for example will export for laser, 3D printer, or Milling. |

Sorry, for whatever reason I was thinking 3D printing not lasers. If you want to do photos, it's a different program entirely. If you just want to etch pattern like you would do with a cutter, then your current cam should suffice with some alterations. For example, taking out Z movement, pulsing intensity, etc. There's quite a few variables. What program do you use for milling? |

im using aspire and i probably think i should learn to walk before i can run lol

Have you done any testing with the laser mode with the new GRBL and UGS? I haven't played with it yet Yes a little. It's convenient in that you don't need to reflash between the two anymore to do pics. |

Here is a video of showing laser settings with Fusion 360. Ignore the post processor part, they are setting that up for a different control system.
What you would probably want to do is set the heights all to 0 so it's not trying to make any Z changes that mess up your laser focus. Then, the version of the hex that we use for a Carve King with a laser has 12000 RPM = max laser intensity and 0 RPM = no laser signal, 6000 = half intensity, etc. If you wanted to engrave the path at max power you'd set the RPM in fusion to 12000 and set up the CAM operation as shown in the video.

Is it a different cam software that you use or do you just save as a different processor What I described above should work with grbl. We do use a different hex file for your control board to enable what they called pulse width modulation control of the laser signal. You can set up most any operation as a contour cutting operation set to "follow path" or "on path" or "no sideways compensation" (the terminology varies) and run your g code through an online applet called "laseroko" that removes all Z travel from your file, in the even you weren't able to suppress it via your CAM settings. You then set your Z height at the optimal focal distance for the laser and rock and roll. |

What materials can be etched? You can etch wood, plastics (NO PVC based plastics; they release toxins when lased!), and burn the paint or anodized finish off of a metal surface. You can cut thin wood slowly (think balsa), thin plastics, foam, cardboard, paper, etc. |

Hmm I need to check into Fusions laser handling. I've been so busy with milling projects I haven't touched my laser since I fabricated that custom housing for it.
