I’m new to lasering, so this might be a silly question.
Is there a way to set the kerf for the x and y separately? I have an Atomstack X20 and the beam is rectangular. I’ve been using a kerf of the average of the two dimensions. It’s semi-working, but it’s not perfect.
Thanks!
No. Nothing like this exists currently as far as I know. And in general I don’t believe there’s any functionality that’s meant to address focus dot asymmetry.
You could attempt to directly modify your design to compensate but that’s not ideal. Would rotating your design by 45 degrees allow your averaged kerf to work better?
I don’t have a rectangular laser, but how did you compute the kerf for either direction.?
How much difference is there between what the X & Y kerf would be?
If you could adjust it, how much would you adjust it?
Doesn’t seem like that could really effect the kerf in any real amount.
The beam emitted by the laser diode is rectangular. But this is normally passed through two cylindrical lenses and this does a pretty good job of making the beam pattern square. You can check this yourself by pointing the laser diode module at a nearby wall, about 3m distance, setting fire power to, say, 1% and clicking the fire button. You will see a clear pattern on the wall and it will be immediately apparent if the pattern is square, as it should be, or rectangular. But, be careful, wear safety glasses and make sure no person or pet is nearby.
The issue is not the shape but the fact that it is not square, specifically that either width or height is greater, thus the cutting or engraving is larger/longer on one axis. Square would be ideal, I am curious if the 4 diodes are the issue here. Or if the same is true of the 10w unit with 2 diodes because I can tell you that the 5w is square.
