Laser height positioner

[Doddy]

That's all very neat.

And e-clips - always handy to have in.

I am curious (££) what a "4.2 frame laser" is, especially with a laser module rather than tube (it's almost worth abandoning a K40 for a 30W solid-state laser)

EDIT: Oooer, just looked on eBay - very attractive pricing. What's your experience with these lasers?, any good?, DoC for ply/acrylic? Hmmm, the first hits on eBay typically quote input power, optical power is closer to the 7-8W in the modules that I've seen. Still useful for many things and a lot less bulk than a K40 with cooling systems.
