How to clean the glass on the focus lens?

Is there any way to clean the inside of the glass on this lens? Residue got inside and it causes the alignment on the passthrough not to work correctly.

In order to access the opposite side of that lens, the print head must be fully disassembled. You’ll need the proper Allen wrenches (1.5, 2.0, and 2.5mm) to disassemble the head casing and remove the circuit board and miniature stepper motor that controls focusing.

It will take about two hours to completely disassemble, clean, and reassemble the print head, a tedious job, but completely doable.


Thank you @yoyodyne2112 . Might have to try if since I don’t have a couple hundreds to replace.

Thanks again. Will post update with result.

If you need some pointers with the disassembly, specifically what to look out for, message me directly.
