When you remove your printer head to clean it, you may notice that the lens is much closer to the bottom of the printer head than when you inserted it with the lens tool. Don’t worry! It's normal for the lens to move inside the head during the print process.
When you make a print, your Glowforge measures the height of your material and then moves the lens inside the printer head to focus it at the correct height for printing. As long as the lens stays inside the print head, it's working properly.
If you’re worried that your lens might not be staying in the right place, follow these steps to check if your lens and printer head are working properly.
- Turn off your Glowforge.
- Grasp the printer head on the bottom as shown, and gently pull up and back to disengage the magnets and remove it.
- Hold your hand directly beneath the bottom of the printer head, and give it a moderate, up-and-down shake. If the lens stays inside the head, your lens is staying in position correctly!
- However, if the lens falls into your hand, there may be a problem with the lens or the printer head. If so, please contact Glowforge Support and we’ll be happy to help.
