Longer Ray5 20w Z-Axis Fine Adjustment Kit: Prototype

This listing is for a PROTOTYPE Z-Axis fine adjuster for the Longer 20w Ray5 laser engraver. It may fit other models, I have reason to believe it will fit the current generation 5 and 10 watt models, as well as the B1, but I cannot confirm that yet. I am offering the kit discounted at this time in exchange for feedback from buyers...not "classifieds board feedback" but a literal message from the buyers telling me how it fits, how easy installation was, problems you had, ways in which it has failed. This kit will come with the carriage, module carrier, knob, and all appropriate hardware. Instructions for installation will be sent to you at the time of purchase. Thanks!
