Hi,
We have a LS1290 with a problem. It is producing a shadow partial crescent when cutting?engraving and not producing the same amount of power it has been recently. Is it: A new tube, Mirrors not correctly adjusted, or something we have not thought of? (It has a new lens fitted).

Hard to say for sure - what sort of dot does the tube make before the first mirror?

Is the beam central to the nozzle exit hole?

Hi,
yes we are fairly certain that the beam is tight and hitting the centres of the mirrors and coming out of the nozzle in the centre. I will check again.

My 1st guess would be final mirror to nozzel .. i.e. reflecting of the side of the nozzel.

Happy man! Managed to adjust the last mirror and we seem to be backup and running.

Thank you all!
