Hi
I have a 1300x900cm 130w ruida controlled China Build laser. And I cant get a good calibration of the laser.
Im using a laser path calibration kit from Cloudray Cloudray Laser Path Calibrating Kit For E Series Laser Head. And Mirror 1 (first mirror after laser) is dead center, Mirror 2 I find also to be in center both in the near and far position (2a and b) but at the last mirror I cant find a good position.
-
If I hit center of the circle in the middle far right position (3e) then the laser beam is to high in the middle left position (3b)
For me that means that the laser beam is to high, and ideally the whole mirror 3 system and lens should be raised - or the laser source should be lowered. But I guess its not important that it hits dead center in the vertical direction - that can be adjusted in the mirror. -
If I make the beam hit a bit above the center I can make it hit (roughly) the same position in both the middle left (3b) and right (3e) position. And now - given that the beam seems to hit mirror 2 in the center both near and far - the whole system should be aligned.
But as you can see from my attachment it both changes in the horizontal and vertical position when the laser is moved. Is the whole system skewed? Or can someone point me in the right direction?
Or is a cheap china machine at 1300x900mm simply to big that I can expect a good calibration in the whole area?
