Hi Guys,
Hope you can help ...
We have a JD 6090 60W laser, purchased new, about 15 months ago. For some time now (last 6-9 months), the cutting power seems to have been reducing until I am now having to cut 3mm acryilc 3 TIMES, on a speed of 3 (really, really slow ... was 20 earlier in the year) and a power setting of 100% in order to cut right through, and even then there are some areas of the cut that don't go right through and need breaking out.
Engraving is fine ... crisp and quick (engraves happily on 300, power of 20).
It has already had a replacement PSU (power unit) this year and a new driver on the X axis, and it has had the mirrors and lens regularly cleaned - not that they seem to get that dirty. Z axis set every time.
Any suggestions gratefully received :-)
