So thread was about air assist fan, and now about not cutting all the way thru?
Yes it can be frustrating–no matter what material you use & the settings, always BEFORE you move the sheet, try to wiggle the item you cut out–if it moves, it’s free. if it seems hung up, run another cut pass. (I learned this after a few times of pulling out the sheet and “oh, sh*t”).
There are many reasons (due to physics & humidity among them that affects the effective power of the beam, or the water absorption/content of the material, and temp of the material (coefficient of expansion) that you don’t get full cut through.
Yes it’s frustrating, but learn to adjust your process to minimize lost material while there’s any analysis of the PG settings vs. material tolerances.
But to be most effective with your unit, especially if you start using non-PG materials, you must learn for yourself how to make adjustments to get your results. There are many, many threads from users over the past 2+ years on this machine that will likely help you out greatly, as long as you’re wiling to learn.
But alas for air assist fan issues, you’ll definitely need to wait for support to get back to you.
