I didn’t see anything but may have missed it…

Anyone used the longmill laser? Have any shipped? I saw it in the shop and im seriously considering it. Would be a great addition.

I bought a 7.5W (output) one from banggood and made a side mount for it beside the router. Awesome little blue sun! But be very careful with blinding (literally) light: care plus appropriate goggles a necessity.  
Cuts light card quickly @ G1 F800. Best focus method I found is to make a little gCode file that is like a ladder with parallel lines 1 mm apart horizontally and vertically. Then choose the Z-height where the line is narrowest:
