Hello all. Hope all is well.
I’ve tried these in the past with minimal success, and the ONLY way I can get these to come out great is by running my laser 50w JPT BWM at real slow speeds with a high LPI setting
It took 7 minutes to get this one. Does anyone have some settings that I can play with that will get me under a minute for these, or there about?
I don’t do much anodized aluminum, but I think you’d get more power to the part if you lower your frequency. You left out what lens you’re using.
I looked at mine and I believe this is for my F254mm lens doing an engraving, not removing anodizing from the part.
I get the most power out of my MOPA at a frequency of 45kHz, according to the source manual.
I think you should lower your frequency and increase the speed.. However, if you have the time and material, might try both by themselves.
A longer lens will make a bigger spot, or de-focus your current lens by some amount. This should result in higher interval, which would speed things up.
There are likely a ton of videos on Youtube doing this 
Thanks Mista J
It’s a 100 mm lens. I’ve been messing around with Freq / Speed, but haven’t found that magic number. It’s no real biggy since I don’t have any orders for them, but I’m sure in heck not going to present it as a service unless I can get that engraving time down to under a minute…
I’ll play around with it some more. It was kind of a cold dreary day so I thought I’d give her a go …
I’ll have 5 birthdays in the time it takes to do 100 of those…
Thankx…
Be well.
Quick question, is that anodized aluminum, powder coated, or paint? On the thick test cards/ thick black coating I do go around 350 KHz, but everything else around 45KHz for coating removal. You could up your power to 100%, and increase your speed to 150-175 +/- to start. Instead of 2 passes Maybe try 1 pass and enable cross hatch. That won’t change duration alone but might allow a little faster speed.
Al… I have no idea on what the metal is coated with, but, I did get the engraving time down to 1 minute, 8 seconds… Settings for my 50w JPT is 2000 speed, 75% power, 100 Freq, Scan Angle 45 for layer 1, and layer 2 is Power 2000, 50% power, Freq 125, and -45 Scan Angle.
Thankx All.
