18 Stainless steel Boss 3655

I have an HP 3655 150 watt laser
I am trying to cut 18 gauge stainless steel.
I have cut it once before about 5 months ago.
so here are my settings.
Power 90 Speed 10
Cut through start and end = 3.00
So after getting an excellent calibration, I send the
project to the laser.
The laser head moves down the oxygen comes on
the laser fires, the head moves back up and the
whole process begins again and continues until
I stop it.
Any help would be appreciated!!
Thanks in advance!!

WOW…nobody?
:(.

Not many people have a metal cutting head on their laser. You are sort of a unicorn with your setup. :slight_smile:

Can you post the LBRN file here, or send to Support@LightBurnSoftware? It sounds like you might have something odd in your settings if it’s not following the path of the part, and just doing the start / end points.

Thanks for any help!!!

You have perforation mode enabled, and a kerf offset. Are these intended?

No sir. I do not even know what that does.

Double-click the entry in the cuts and layers list. Turn off Perforation mode (make the toggle red), and set the Kerf offset value to 0. Then re-run the file.

Wow…That definitely helped!
So now it is going thru the cutting motion.
After adjusting the oxygen it kind of cut thru with a splatter effect.
So I adjusted the oxygen some more and it quit cutting and just
marked the stainless.
I adjusted the Oxygen back to 100 and still the same.
I adjusted down to 85…same thing. I adjusted up to 120 same thing, barley a mark.

For the actual cutting settings I’m going to refer you back to Boss’ support - they should have guidance for this, and I haven’t worked with metal cutting or oxygen feeds before, so I’d prefer not to kill you with bad advice. :slight_smile:

Sounds like you have an oxygen problem either not enough or not hitting at the right spot any acc and the proper oxygen it should cut

OZ… I really appreciate you. Have gotten ALOT of insight redaing your responses to peoples questions. You are the Main!
THANKS!

Jimsher…I think you are right…I was running out of oxygen so that may have had something to do with it.
I am getting my tank refilled now.
Will let ya know how it goes with a fresh tank.
Thanks for your response!!
