Hi all. First time poster. Not entirely sure how to post, but here goes.
First photo (assuming I can get this to work). This is the process parameter for Magenta color on titanium sheet material, T2, 0.7mm thickness with a 60w MOPA with a 290mm lens. It is a super color on the sheet material. Please notice that the pulse width is set at what I am given to understand as the lowest setting, that is “2”, and the LI is 0.001. My first thought was that, given the LI that I would burn through my sheet. Well, it doesn’t. It burns beautifully. Yes, the speed is not slow, but it is not all that fast either. The frequency is on the low end for my machine, but is in the 400s, so I didn’t think that was so low. The power is high, but the surface on the sheet is still smooth after the burn, so my thought was that the moderately high speed and frequency, plus the shortest pulse width were the mitigating factors against the high power, with the LI pulling it in the warmer direction.
Well, ok, so I’m looking around for this color to burn on a somewhat different but similar substrate and I ended up with the process parameter settings of the second photo. Same machine, same lens, still T2. This setting nearly burned a hole in my material, and I still cannot understand why. The speed, power and frequency are not set for much higher heat, maybe a little, and the LI is twice as large as the Magenta in the first photo. The difference is the pulse width, which I moved up to 10 (from 2 btw). I have many many many parameters with pulse widths much much higher, in the hundreds, and they produce nice smooth surface colors.
So, my question I’m starting to think may not be a hardware issue, but a LB software issue. I’m beginning to believe that the pulse width as entered is not working on a scale that the client program reports accurately. Maybe I’m in error, but these settings do not make sense to me.
If there are any veterans out there that have some understanding of this issue I hope you will find a minute or two to possibly address this issue.
Thanks!
Dany
