At last .. my own lasercutter

Last Updated or created 2023-03-06

I did a lot of lasercutting at Fablab Utrecht, but they stopped a few years ago, and I moved to Hilversum.

I loved making this at this Fablab.

  • Lasercutting : Boxes, A cryptex of my own design, Xmas ornaments, Shogi game, things in acrylic, Rubber stamps
  • Cutting plotter ( Nae Bother Case logo’s )
  • CNC Machines
  • Vacuum form

Then i bought a mini engraver, which you can attach to your 3D printer.

But I really wanted a cutter, so there it is … the Sculptfun S9

First test. crafting paper. No burning and a really high resolution!

This laser module has a new optical design, so it can cut wood as thick as 10+ mm.
It can engrave metal, cut non-transparant acrylic, leather and more.

Software:

I’m using Inkscape, with the lasercutter tool plugin from Jtech.

I’ve also tested with LaserGRBL, which can be run under linux using Wine.

I’m trail testing LightBurn. (Native Linux App)

I will post my findings and test on this post.

Calibrate your machine! .. But NOT as found on YouTube using a 10x10mm or 1 inch by 1 inch. square.
As big as you can. This is far more precise!

My list of settings (Work in progress)

I have to check mm/s versus mm/minute!
