Hi i've got a strange problem when cutting thick (10 mm) acrylic
I use a 60 watt CO2 china-laser, when i vector cut something the edge looks very strange to me ( see attached jpg)
The cutting edge seems to be a bit hollow.
I don't understand what could cause this kind of edge
I have tried all different kinds of settings checked the beam alignment as good as i can but i keep getting this edge.
The drawing represents the edge of the acrylic cutout, this cutout was made at 80% power and a speed of 4mm/sec.
Has anybody got any idea what could be causing this?
Best regards,
Ferry...
