Laser producing flame

When my laser makes a cut vertically (back to front of machine) it produces a really big flame. But side to side cut, there is no flame at all. Anyone had this happen??

Make sure all of your mirrors and the lens are clean. What are you cutting?

When was the last time you thoroughly cleaned the air assist fan? Is the smoke from the cuts being blown toward the front of the machine? Does this happen with all materials?

This happened to me when my air assist fan was dirty.
