Hi,
The below is my suggestion,hoping it can help you.
1.For engraving on leather and alcantara,40W/60W both are ok.
2.For the leather,alcantara materials is soft,so i think it should not need to use the rotary attachment.
3.Need to use honeycomb platorm.
4.Can you tell me what is the thickness of the leather,alcantara? If you cut,thickness is needed.
5.What is the length and the width of the materials?
6.Exhause fans ,all are machine have.
7.For the chiller,usually 80W laser tube or bigger,we will suggest install.
If you have any other question,please feel free to contact with me. My name is jenny ,i am in the fields nearly 8 years ,email is
