I received my Emblaser Core last Chirstmas (2020) and since owning it I have only cut maybe 12 things, which have all either been paper or 3mm MDF.
I have the air assist and recently built a box for Emblaser Core and purchased and installed the extraction fan (from Darkly Labs shop).
Excited to use the Emblaser again after finally finishing its enclosure, I have run into problems.
The laser no longer can cut through my material.
The material library settings in Lightburn supplied by Darkly Labs always got the job done; however, even if I double or triple the number of passes, I am still not cutting through the material.
I have fiddled with power/speed/passes settings and have only been able to cut through printer paper and 100 gsm paper stock.
I have run all the calibrations and cleaned the laser lens on multiple occasions, and I still have the same problem of not being able to cut through my material.
The silicone laser cover nozzle is on correctly as shown in the instructions.
I am worried I am missing something, so I have supplied some photos below to hopefully help identify the issue.
This is 3mm MDF with the normal material library setting of
Speed: 200 Max Power: 100 Support: 10mm Material: 3mm
But I increased the passes from 2 to 6 total passes.
This is the back of the material after the job
I started doing tests with different speeds and passes
