Omtech 60W Ruida 6442 Mac mini M1
Simple question! I just received my Cloudray Compound Engraving Nozzle set 18mm. Focus lens are in two different colors. 38. is light yellow, 63. is more orange. Am I correct?
Certainly seems there would be some simple instructions for installing this unit inside the box. ???
The 38. has less curvature than the 63. Is that also correct?
