Can you share the settings you used for the slide?
Not sure who the questions are directed to, but for my settings, on metals I tend to like the MacBook Pro settings, but needing to change the focus height.
On any polymers, this is a setting that is per material and best not to give a direct setting, as what works with mine may not work with yours.
I’d say though, start with MacBook setting and lower the power to almost nothing and work your way up 5% at a time, and stay away from FULL POWER on polymers! Also you must remove crumb tray and build up a bed for the height that works for your parts. Crumb tray is about 1" 1/2 if I remember correctly.
