Look at the curve of your cut line if you go faster the bottom may not keep up with the top so with your setup your feed is fine. You have a good quality cut that any customer will be happy with so run with it.
Your heat issue can be many things so at this time more info would help. If your focus is off you can have this issue. If you run too slow for your cut conditions and heat up a larger surface area you will see this problem. What is the inside dimension of the U? All the 1/2 we cut is with...
If it's anything like the Amada lasers if you run in high speed mode (HS) the head will drop down in any hole because it's looking for the material. So when the head moves from one hole to the next if it runs over one that is already cut the head will drop down and clip the edge and it will...

Aluminum is just like stainless this is what I do. Try it and let us know what happens because you could have contaminated nitrogen or it could be as simple like a focus or gas problem. You may need to do a focus test to check the lens. So many things could cause this problem so lets start...
In the past I would run the program with all cuts on E10 first and change the feed so it would cut the plastic but not mark the material. If you try this change all the M103A6 to M103A0 so it will not pierce. After the etch is done run the program that cuts out the parts and see how that...
