we have a cloudray 50W JPT fiber laser. It is a fantastic tool but we have many small challenges. The intended use is for creating watch faces in 0.5mm brass. I have spent a full weekend calibrating, and following all instructions carefully. Saturday I had great success engraving to 0.25mm depth with these settings.
.0100, no crosshatching
we set it at 66 degrees and to autorotate, (we are creating round watch faces and this is to secure we don’t get any stepping in the cutting)
we did 12 passes, then a clean up pass
.0250 cross hatch
then we repeat.
worked perfectly and the parts came out super clean…
yesterday we used the same settings and after the first round the laser had burned thru.
after burning thru.
We updated the settings
.0250 no cross hatch
123 degrees - auto rotate
then a very similar clean up
this worked great
is there something we ae doing incorrectly we are certain that the settings we are using are not incorrect from what I have wrote but we get extremely differing results on different days.
this is of course a very big challenge as we have been struggling for weeks with this and have generally felt that it was the LightBurn software, I am at a loss so we are looking for some help?
