Oh thanks for this,is is a nice alternative to the build log form, less fiddly, much easier to use!
I should explain how I came to be on this forum and why I am still asking questions..! I bought a home made laser from a guy here in the UK and tbh, if he had taught me everything to know about laser cutters I would have had to live with him for two weeks. He bought the AWC608 from light object and I was looking for the upgrade files.
So, off and on its been a bit of a learning curve and there isn't one resource for all your laser cutting needs! I've gone through learning about thermal shock, algae in the coolant, having enough coolant ( he sold it with 5 litres of uncooled water as he only used it for maybe an hour at a time ), learning the black art of lining the mirrors up, connecting the high voltage cable up safely, snapping the end off the coolant inlet
![Shocked :shock:](./images/smilies/icon_eek.gif)
stepper motors, the dreaded backlash, PPI, PWR etc etc...
So, question..... If I move the tube aperture closer to the first mirror, will this reduce the divergence?
Of course I am assuming that if a beam hits a mirror with a small divergence it keeps diverging at that angle and diverges more the further away it is from the source.
I'm also considering a beam expander in the future now as I should be able to get a smaller spot size. I think I might be getting a bit geeky though as others manage fine with out that!
Thanks for any comments
