Hey Guys!
I got a new lens with a smaller focal length to help get some better detail out of some acrylic jobs I've been working on. The problem is the distance from the nozzle tip to the material is 5mm. So what's happening is that the residue from the acrylic is building up on the nozzle and it's falling off on the acrylic and then can't raster though it, and / or it's closing off the nozzle tip and causing the same issue.
When I'm rastering I do have the air assist OFF. If I do turn it on, it tends to scatter the material which ends up back on the acrylic and leads to a fogging effect, if that makes sense. But I do have good airflow from the extractor/
Currently I'm just keeping my eye on the job, stopping the laser when it builds up and knocking it off... but I have to say this method sucks... I'm hoping someone has a trick or something
Thanks!312677
