I have just purchased a Transon 1390 CO2 laser engraving machine. It is a 100 watt water cooled laser. I have been getting strange ripples in the materials i am trying to engrave. I am using software called LaserCut 5.3. Every power and speed setting combination I try is giving me the same results. I have checked the belt tension, the alignment of the mirrors, made sure the machine was grounded properly, and have still getting poor results. It there anyone that has had this same problem with their machine or can help me resolve this issue? I will post pictures of what I am talking about for a better understanding. Any help would be greatly appreciated.
