I have an LC6090 80 watt Jinan G Weike laser cutter/engraving machine.
i am using mainly for engraving images onto slate and granite, i use lasercut 5.0 software, upload .bmp images at usually 300DPI. 100% power 500mm/min.
i have got air extraction and an air blower into the nozzle!
I have had very few issue's with this machine apart from the following:-
-I sometimes have an issue with streaks the full width of the engraving intermittently.
-When engraving very large images (600mm x 900mm) i find there is usually faded patches spotted around the engraving??
-When engraving an image with text next to the image, i find the image will be faded in the exact place of where the text is (on the same 'X' axis path).
Any help would be much appreciated, i am new to this site and would be happy to give any advise as to my experience of this machine and my process.
Regards
