Upgrading To An Ortur LU1-4 20w Fixed Focus Laser & Lasermaster Grounding

Gearbest sent me one of the new ORTUR LU1-4 fixed focus lasers to upgrade my LM2 at no cost to me and this is a video about switching over my LM2. It's a 20 watt input with between 4.5 and 5.5 watt output power and no focus ring to mess with. Also decided to add the recommended grounding. Here are the instructions. https://ortur.tech/documentation/olm2/Ortur_Grounding.pdf
I recommend everyone add the grounding and from what I understand Ortur is making a kit available if you need one.
