God day everyone, the other day I tried to align mirror on laser head on Chinese 60W laser as I tought it may improve efficiency but it hapend oposite. Now I can not cat 5mm playwood that i could do before. I used masking tape method on head where burnt circle appear. I tried to tune it as posiible to be in circular shape. Now when machine is not working I can see red dot on floor of machine to be in egg shape, it is noticable as it is far from head of laser. My question is does this out of shape light means that aligment is not complete and should that be adjusted in mor circular shape. Also if you could provide good tutorials how to adjust mirrors to work correctly? I adjusted miror on top of head only , not toching others. Thank you.
