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...

Approach is your lead-in line so whatever conditions you use will start after the pierce, edge data is used on corners.

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...

You can use a 5" up to .179 when the optics are clean but it's more forgiving if you stop at .134 with the 5".

What laser do you have? 6mm is like cutting .25 and we use a 7.5" lens with a 1.4mm nozzle. A rule we use is 10 ga (.134) or less use a 5" lens with a 1.2mm nozzle and a nozzle gap of.060. Anything over that is a 7.5" lens, 1.4mm double flow nozzle and a nozzle gap of .028.

I never used shop air because if you don't have a good dryer it can cause some problems if water gets into the system.

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...

It shows the last update on the pierce page was on the 23rd so if not you someone changed something.

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...

We have Ryan as our rep and he's doing a great job so now we are on the right track. I was looking for others that have the Amada 3015 and how they use SigmaNest because of the low memory. Ryan got more done for us in two visits than everyone in the last 3 years

You have to use nitrogen with wood to keep it from catching on fire.

Thanks Ninja

Are you talking about all the cut conditions being gone?

They should work but you will have to adjust your feed rate especially on the settings that call up 2000w.

We've been working on the post for our 4 lasers now for over 2 years and I still don't have a working post. When we get close they give us a new guy to work with and we have to start from scratch. We are on our 5th guy and finally this guy is great so we should be up and running real soon. I...

We have 2 older 3015 and use array nesting with G98 lines and that works fantastic but SigmaNest can't get the G98 line working. If they took the best of AP100 Alfacam and mixed it with SigmaNest that would be a great program. I guess the 20% of us that use array for nesting just have to deal...

Is anyone else using SigmaNest with Amada lasers?

Now that is what good nitrogen cuts like. Good job.
