   * The edges of the thin [[https://hobarts.com/1.5mm-black-on-white-laminate-610x305mm-ref-2901-|1.5mm laminate]] can get burnt when cutting is done in one pass
   * It might give a better result if cutting with multiple passes at lower power
+**Glass**
+  *Glass can't be cut on the laser, but it can be "engraved", in that the surface of the glass chips when under the heat of the laser, leaving a frosted surface (careful, as tiny bits of glass can break loose).

+**Rotary Axis**
+  *The Big laser has a rotary attachment for engraving and cutting cylindrical objects
+  *To use it:
+  *lower the bed of the laser down until you can see 2 switches and a socket on the right wall of the cutting area
+  *bring the laser head to roughly the centre of the bed
+  *plug in the rotary axis and flick both switches, this changes the laser from controlling the up/down motor to controlling the rotary axis motor
+  *cutting and engraving is done exactly the same as before, you may need to adjust the vertical scaling to get a nice result
+  *when you're done, don't forget to return the laser to the state you found it in

+  * Costa has made a nice jig for bending acrylic at precise angles, consisting of nichrome wire, 2 board boards and a hinge https://www.instructables.com/id/Acrylic-Bending-Tool/

   * Good explanation: http://archive.fabacademy.org/2018/labs/fablabsiena/students/giuseppe-allocca/laser%20cutting.html
   * The laser cutter has something called “kerf”, if you send a 1cm square to the laser, the part will come out slightly smaller (~9.8mm)
-  * This difference is about 0.1mm, so paths need to be offset by 0.1mm to compensate for this.
+  * This difference is about 0.1mm, so paths need to be offset by 0.1mm to compensate for this using the offset tool in Lasercut 5.3
   * Fusion 360 has a plugin which does kerf correction automatically: [[https://apps.autodesk.com/FUSION/en/Detail/Index?id=7634902334100976871&os=Win64&appLang=en|link]]
   * This should also be possible with the “offset path” tool in any vector editing software like Inkscape or AI
