I was cutting 6mm mild steel the other day, and the cut was good enough.
Power was only 1100 and speed was 1500.
This was the maximum speed I could run at this power level.
I figured I could rise the power and gain some more speed, but no matter what i did, I could not get a clean cut with...
But keeping the head high by "lying" on the thickness will put the focus point way off your intended point.
Why not just add the inches to the nozzle gap?
mikeybob125,your settings shows thickness 1.16" but you are only cutting 0.75".
Are you using this clearance to keep the nozzle above the wood because the height sensor isn't working?
Will it be correct to guess that the total nozzle gap will be 0.06"+(1.16"-0.75")?
The machine I bought came without any cutting parameters for plastics - only for metals.
I did try to cut 1" round test circles from the ABS a few days ago and the result was catastrophic.
At first the laser did not pierce the ABS and the cut was made only half way deep, the amount of smoke...
Our story starts yesterday when I spent 4 hours trying to get a clean cut on a 6mm stainless steel.
After 4 hours with no luck, I had to do something, I had to start cutting.
So, I did.
The cuts came out black with sharp burr and all dirty with splatter.
But at least I made the cut.
So today...
Well, apparently my pierce conditions were wrong, and now with your parameters the pierce is much cleaner and faster.
Attached are the new pierce condition 103
And a sample cut with this pierce
But that does not solve the black cutting surface.
I am trying to think outside of the box, maybe...
I never paid special attention to the pierce.
Always thought: if it goes all the way thru - its good enough.
I will take some pictures of my pierce (only tomorrow) but from what i remember its quiet with sparks going in all directions for about 3-4 sec.
Even if the pierce is good (or bad) why...
Not a very good day today.
I started the morning with 4 hours of trials to set up new parameters.
Ended up with something not as good as I had but a bit faster 700cm/min instead of 500cm/min.
Tried my old settings again, and it did not cut as clean as it did on the first time
Nitrogen pressure...
I found all those parameters the hard way.
It took me several hours and more then 30 pcs of trial cuts to achieve a really clean cut.
All those testing were done when the machine was only a few days old, and I had no idea how and what should I change to make it work.
Tomorrow I am starting a new...
