Someone asked about the settings I used on a few projects so I figured I would add them here in case anyone can use them.
I have a 50W Fiber Laser. I use a 110mm and 175mm lens most of the time depending on what fits. Settings: UPDATE: I just discovered a formula I did not know before. I was using trial and error however this formula gets you the frequency needed for max power output. Take your advertised power rating and divide by the max pulse energy and it gives you the frequency for maximum power. So for my JPT M7 80W: Laser Power JPT 80W / Max Peak Pulse 1.5 = Max 53.3333 Frequency or 53 mHz For the MAX 50W below: Laser Power Max 50W / Max Peak Pulse 1.5 = Max 33.3333 Frequency or 33 mHz The manual for the JPT also shows the Q-Pulse cut off scale so on that a Q-Pulse of 500ns.

Quote HistoryOriginally Posted By OG1: I got this one https://www.ebay.com/itm/126166158159 (they threw in the rotary free after adding to cart as an incentive) using a Max 50W laser source. You can do the same with a cheaper 20W it just takes longer. If you want to do colors on stainless look into a MOPA. If I had it to do over again, I really want the Monport GA 100W, it does a lot and they have deals much cheaper for on ebay than the website. Insane how cheap fiber lasers are getting. I got my Monport 30w on Ebay for $1,800 with a Raycus source and no rotary. But I agree, if I had to do it all over again I'd get a JPT MOPA. |

Thank you very much.
I was coming here to ask for some help with deep engraving in steel. This was exactly what I needed. |

Quote HistoryOriginally Posted By OG1: Awesome. Just run as many passes as it takes on your machine to get to the depth you like. The settings for that will work on any lens or power, I keep that the same on all 3 lenses I have but go deeper on the 70mm and 110 of course. The frequency is also where the depth comes in, run that as low as your machine will allow. I ran the aluminum settings with a global of 3 instead of 2 on this one and really like the way it came out: https://www.ar15.com/media/mediaFiles/289319/airforce_jpg-3275710.JPG That turned out great, I may have to do one. My friends son just joined the Air Force. just tried those settings, got good results but it doesnt look like im getting as much depth as you. I have a 100W MOPA. ran it at 75% power. Still need to play around more with it. Also for the Scroll work you've done, are you designing it yourself or using software? |

Thanks some nice work.
Thanks for the settings too! I'll be converting them down to my 20w Raycus after work.  I'm still working on marking some cheap white acrylic dice, but PMag, SBR & 80% are next on my list. |

I've been having a hell of a time working out numbers for cheap white acrylic dice.
So far, on a 20w Raycus, 110 lens, I'm at 800mm/s, 40%, Freq 60, line 0.05, and anywhere between 1 and 10 passes (solid images lower, thin vectors more) I may give in and sacrifice more to a material test matrix or two now that I have a rough range to look at. |

About how long does a roll mark burn like the armalite one you show take and what is the actual depth? I presently have a CNC router and am seriously thinking about getting a laser, your handy work is giving me a big push.

So you have upgraded to the JPT 80w, would that be the one that they refer to on Ebay as a Preeneex? Are you happy with it?
You obviously are very experienced. I see a lot of negative comments about just about all of the manufacturers (Monport, Omtech, etc) on places like Reddit. Is that because a lot of the people are not very technically competent and the manufacturers don't provide much support or are these Chinese made lasers truly not very reliable?.....Thanks for any input, Mike |

Quote HistoryThankyou thankyou thankyou, That video you recommended was exactly what I needed at this point in time. It sorts out a lot of the jargon, brand names and technology types. I am just starting my trip into the world of lasers and although I have experience in CNC and other manufacturing processes I knew nothing about lasers. It seems to be a fast moving technology and a lot of information out there that is more than a year old is pretty much obsolete. Thanks again, I'll probably be back with more questions seeing as firearms are also a hobby of mine. |
