Clean the lens of sculpfun S10

how to clean the lens of the sculpfun S10???

You remove the air assist nozzle (you need to unscrew a small grub screw) and then screw the whole nozzle off. Then use a cotton swab and isopropanol to clean the lens.

If you are always using the air supply, there should be enough positive pressure that there will be little to no contamination on the lens at all.

thanks for the answer
