30W Fiber laser settings

I’m looking for some good guides, describing settings used in common materials.

This is mostly, Titanium, Stainless steel, Steel and acrylic. Also using a rotary axle.

Does anyone have a good place to start, regarding speeds, frequency, power ect.

thanks in advance.

Besides the Russ Sadler videos of how it works internally and some examples, I think the best general collection of videos is from the laser everything group.

This should also help … they used to charge for these… in their masters academy.

Forget acrylic… passes right through…

Have fun

Perfect Thank you. Regarding the rotary Axle. Is there a good way to calibrate this. When using lightburn, it jitters a lot, with some overlap, unessasary rotation. And also the speed. But gets the job done.

There really isn’t much to do with a chuck type rotary. The motor driver is set to a specific steps/rotation and the software can’t change that. That’s one of the things you have to tell it.

Unless you have a gear ratio from the motor to the chuck. It’s all digital, so it’s more likely to work than work poorly.

What I found with mine, was that the split size needs to be a multiple of the interval. That seems to help on mine.

I wrap my objects in black masking tape and run the job at low power to mark only the tape… when it’s right I run the job at the right power.

Might want to elaborate on the type of erratic movement you are experiencing… I too have had it to strange movements, but I think I don’t know enough about it.

Try this with your fiber – worth a watch :crazy_face:

Found another video, I’ve configured the overlap and the movement incorrectly to my needs, this explains the weird movements. :slight_smile:

Did it fix it?


It Helped. I’ve found out, that the overlap does fix the ragged movement. And the Hatching settings can be altered to fit my needs better. It’s a learning curve, but it’s so much better than the Ez cad crappy software :wink:
