Ortur Laser – Detailed Build Instructions in Less Than 15 minutes!

In this episode, we will be providing detailed build instructions for the Ortur Laser Master II (see more here: ) and while this is the 20 Watt (input) version, the major of the build will apply to all versions (i.e. 7w/15w/20w) of the time. This is a step by build along video which will take you from start to finish!

Build Notes:

1. Read instructions (easy link to online manuals: ) and follow all safety guidelines.
2. The acrylic on the newer verses seems to be thinker so the old 3D printed cable managers might not fit so look for an updated version on the Design Store ( )
