CONFUSED OVER DIFFERENCE IN POWER
In October 20019 I sold our 3020 and in December bought a new one, both ostensibly having similar 35 watt tubes.What confuses me is that I need at least twice the power and about 10% less speed to cut the same materials. The new one cuts fine once the speed/power is established but just wonder why?

Re: LASER ALIGNMENT
Fixed all my current problems - had the laser tube replaced! Had forgotten how quick and easy cutting could be! Nothing that money couldn't fix!!

Re: LASER ALIGNMENT
Morning! Thanks for that. The coolant flow seems to be fine with no air bubbles etc. I'm not quite sure what I am looking for when you refer to the output coupler mirror. The first mirror the beam hit seems nice and clean but I think you are referring to something inside the tube near the end? There...

Re: LASER ALIGNMENT
I have been having further issues cutting 3mm ply with my LS3020 which I had down to variances in the quality of the wood, but I am beginning to wonder if other factors are at play. Out of exasperation I upped the power to 80/80% and increased the speed to 30% (For two years I had cut at 22% speed a...

Re: LASER ALIGNMENT
Is there anyone else having persistent trouble cutting 3mm birch ply? For quite a while now I have had to change my settings virtually every sheet. Not only that I can have several similar cuts side by side and some cut through and some don't. For a couple of years I had the same settings day in day...

Re: LASER ALIGNMENT
Good thought. Just to clarify, if I am cutting 3mm Perspex and my focal distance is normally 73mm I should increase this to 74.5mm?
Best regards, Richard

Re: LASER ALIGNMENT
I am now experiencing an issue that is really only apparent when cutting Perspex in that the cut is slightly bevelled - only a small amount, but when it comes to glue-welding pieces together there is only marginal contact. It would seem obvious that the laser is not exactly square with the table, bu...
