When the out put of your laser is too weak because of age then you can tweak it to a lower value e.g. How many of you own one of these lasers? What do you think. This parameter must match the S parameter within the Mini Gerbil although you can change it to a custom value to suit your needs (make up for aging or worn tubes). The Raspberry Pi is great to use as a dedicated computer on machines like the 3D printers, and I really wish that a similar system could be set up easily on a K40 laser. Although, I can fiddle around and get a program up and running using a Raspberry Pi, it is nowhere near as good as the OctoPi setup on my 3D printer. The 3D printer and Octoprint/Octopi setup has become a permanent bit of gear in my hobby/workshop.

I own a Creality Ender 3 Pro, and before owning it I couldn't understand why anyone would need a 3D printer.

I reckon that the Octoprint system using the OctoPi program on a Raspberry is a brilliant product, especially when set up to work across my home network. Many makers own the budget K40 chinese laser cutter.etching machine.
