May I but in just for a very few quick questions? These are so silly, but I even don't know proper search words :bang: 1) Is there any fundamental difference on these laser engravers and one used only to mark metals and such? 2) These are basically a 2D cutters right? Do they have Z for any reason? 3) Is the laser tube or part moved or is the ray guided by mirrors/prisms/fibre whatsaman callits? Thank you, Pekka |

Hi Pekka 1-This will only have a 40W CO2 laser you would need hundreds of watts to mark metals or use a YAG laser There is a product called Thermark which will work with CO2 lasers http://www.thermark.com/content/view/16/86/ But this just permanently bonds to the surface 2-It is basically a 2D cutter/engraver it will have a table which will be the Z axis to raise or lower the work to bring it within focus of the laser 3-The laser will be completely guided with mirrors the tube remains stationary The laser follows the path shown below in yellow |

Thank you :clap: I didn't have a foggiest idea - I was really far off on how much power it would take. Dim idea lamp lit in my head: This could be used to mark locations on the metal blank prior to fabrication, but I think I'll try to get more consistent in scratching markin out blue....I would have been cool to "etch" mark out on steel part prior milling and drilling. Could have avoided the 1mm or 10 mm mistakes! The link you put was intresting. Pekka |
