Thread: Help configuring/troubleshooting Chinese 20W Fiber Laser, Maxphotonics, EZCAD

  1. #31
    In the 'learn something new every day' category-- I just fiddled with the 'angle' setting, and yes indeedy it does rotate the entire output! After a couple of minutes I came up with a -0.38 rotation that perfectly squared the output to the faceplate of the machine!

    I also learned that the tweaks made in the "field" tab window affects the laser AND red light output. I also noted that after squaring the output, the red light lined up perfectly to my test engraved box in the Y axis, but was just a hair short in the X axis; I had to add .007 to the X scale in the red light adjust window. Now, I'm not sure changing the rotation had anything to do with that or not, it might have needed a tweak before I did the rotation change, I'm not sure. But I'm glad I checked, the red light and engraving line up nicely!

    Hi Kevin. Im having almost same power issues from my 30w laser. When you are referring to mirror alignment, do you do the adjustments with the mirrors with the laser in the on position? How do you actually move the mirrors?

    Moving the mirrors-- Just draw a box or circle that takes up the entire working area and run the red light. Best is a circle actually, drawn large enough so the circle reaches the 4 corners of the work area. The circle will extend beyond the flat sides, but this is good, as it moves both mirrors at almost their maximum travel, and centered TO the work area. Adjust the red light emitter so the red-light travel is centered both directions on both mirrors, as in my pics.

    When done adjusting the red light to the mirrors: draw a full work area size box, and engrave it on something. Then, run the red light to find out how close it tracks to the actual engraving. With the red light adjusted, the goal is to get the laser to match the red light as close as possible. This involves adjusting the laser 'snout' inside the machine or scanhead housing, which will be a lot of trial and error with paper shims and such

    But if you can get it close, you'll know the laser will be hitting the centers of the mirrors and lens, keeping power output equal throughout the work area

    Final adjustments to match the red light to the engraving dead-to-rights can be done last in the software. These will be very small adjustments that shouldn't affect power output at the edges of the work area...
