Hello,

Im new to the co2 laser cutter and still testing the machine. It is 140x90 130W chinese red and black box. I do have a hard time with align the mirrors. Went through several videos and it seems that i did everything correctly but i bet i did a mistake somewhere if it does not work as it should be and i need your help. Basically while i hit pulse in all 4 corners i do have same dot spot on the tape on the last mirror whole. In the attachment im uploading the board and the area where laser is going off - basically power is missing (is not able to cut 4mm on 75% / 18mm/sec, the line is off (next to the cut line there is a burn border) as well as i do tape and pulse test the laser is simply going down off the center. Do you have any clue what could be possibly causing this issue and how to solve it?
