When cutting Acrylic with a CO2 laser, lines appear on the cutting edge every 5 mm.
Laser: 90 Watt CO2 Laser
Material: Extruded acrylic 6 mm
Speed: 6 mm/s (tried up to 12 mm/s)
Power: 70%
The material hangs 10 inches above the bottom.
Can you get us a picture?
I just updated the post
It sure looks mechanical!
Does 5 mm correspond to the circumference of the wheels / bearings or the belt tooth spacing along that axis?
Although it seems unlikely, perhaps the setscrew holding the pinion to the motor shaft (or jackshaft or whatever) has come loose and produces a hitch in the gitalong once per revolution.
Which surface are the marks on? They could be reflections from the support grid/rails underneath the acrylic.
Thank you for your advice. It was mechanical.
I was cutting along X, and when I checked Y, there were no issues.
There were no visible problems with the belt or looseness, but I reinstalled the wheel on the X motor, which fixed the line issue.
Thank you again.
