Update November 10 2018
After much delay and I have to say patience from Banggood, I have now put together this excellent A3 laser engraving machine. Originally, a 500mW module arrived complete with its own power supply (the laser which was not included in the basic kit). It turns out that was the wrong laser and now I have the 2300mW violet laser complete with upgraded 2.5A power supply. In the photo you also see the (important) green protective glasses that came with the kit.
With help from my friend Aidan who has extensive experience with 3D printers and similar, we’re now putting together some Perspex door signs for bedrooms at Willow Cottage using the Eleksmaker (more pics soon, Sylvan Azure and Occitane are the bedroom names for the dooe signs).
