A couple of weeks into my Laser journey - Bought a cheep 2nd hand 60w Red/Black clone to learn on.
Day 1: Topwisdom Controller fried on turn on
Day 2: I fitted Ruida RDC644G (which came as a spare with the machine prior to Topwisdon being supported) with the help of a YT video.
Day 3: Copied all the settings from a post in this forum and got it up and running.
Day 4: Fixed the non working LED Dot (loose wire)

Week 2: Latest issue with reducing power to 0.1 and Laser still firing.
