Cannot get my laser to create any lines on the calibration card using the LightBurn laser calibration tool. The beam seems to be very large and will not make a mark on the paper. Z-axis movement is fine. Any ideas? ---

Sounds like your laser beam is out of focus. You should only have a small dot. If your beam is large, it won’t mark at all. ---

That’s what I figured but I don’t know how to go about focusing it. My machine is an emblaser 2 and the laser won’t fire with the lid open. Any way to manually focus the beam? ---

Having the lens upside-down might throw you off. This may be worth review: > **[Troubleshooting Focus Calibration Issues - Darkly Labs](https://darklylabs.com/article/troubleshooting-focus-calibration-issues/)** > > The Focus Calibration wizard is accessible from the Emblaser dropdown in the menu bar within... It’s interesting to see the custom Emblaser (Darkly Labs) menu. ---

Thanks, JohnJohn… I will check and see if the orientation is correct. ---

In case anyone else comes across this issue on an Emblaser: It appears that the Collimation Lens has become de-tuned. This is very rare and will unfortunately require servicing to resolve. I recommend contacting the place of purchase, or Darkly Labs directly, who can assist in identifying a solution as we have done in this situation. ---
