I've been playing around with a 30 watt fiber galvo laser - IPG laser source - 175x175 mm lens - running EZ Cad 2 for a few couple days.
A few things I've run into, hoping you guys have some experience that might help:
1) What's the max variance I should expect? What's my depth of field variance on a galvo like this when going around a slightly curved object?
2) Polished stainless steel - My annealing is turning out spotty instead of black on the polished stuff only. The matte stainless seems to work ok, but the polished stainless I'm having trouble with, any tips for polished stainless that might work?
3) Any tips/tricks for stainless steel in general?
4) How do you keep track of job height so you don't have to remeasure every time? A good way of knowing the focus distance exactly every time...
