Would it be possible to slow the pulse frequency right down, keeping the power per pulse the same, such that the number of pulses per inch was the same for the beam traveling slowly (ie. doing the...

Thank you Kev, a good explanation.

Is the speed mainly an issue due to the increase in time the job will take or it is more of an issue that the beam needs to be moving fast to get a better quality engraving ?

I think this upgrade would be a big improvement, however I've not been able to find out much more about it or find it's model number or read the manual.
I've been told that the controller from scaps...

Is there a reason for it being common to split / segment the design rather than following a vector as would be done with mechanical engraving and which you'd think should work better for this type...

Thanks,
How would this segmentation method work when engraving a ring with a curved (D-Shaped) cross-section ? The diameter is larger in the middle of the ring and decreases as it goes towards the...

Hi Nick,
I'll check it out.
Thank you,

Thank you Tony, I wasn't aware of them, I'll take a look at their site.

It does seem to be an add on board, but no doubt not cheap and with it's own problems.....
Strangely difficult to find more info or a manual for it.

I would have thought that such functionality...

Thank you Kev, that's very useful information.

I did find a youtube video of rotary vector engraving which would be seamless, but haven't been able to find out any more about the "BJJCZ marking...

Thank you John,

Still new here, I've just set up the annual subscription and can now see Kev's and your photos, they're nice clean engravings.

Here's a couple of the rings I've made, all...

I can see how text would be relatively easy to engrave on a ring, however I engrave continuous designs which would have to be seamless throughout and to meet up seamlessly at the start/end of the...

Hi Kev,

Thank you for your thoughts on this.
I'm primarily wanting to engrave rings, however I see a lot of posts of people having various issues when using a rotary axis on their fiber...

Should I have posted this in the Engraving-Hardware-and-Software sub forum ?
Can it be moved ?

Would there be any more danger to the optics than a typical scanhead fiber laser ? Would it have to be a much shorter focal distance ? If so then could you add a cutting head style shroud with air...

Primarily I'd like to make rings in titanium, silver, gold, etc.
I currently do this using a high speed spindle on a small milling machine.
I'm assuming that focus could be set by adjusting the...

I've been looking at fiber laser engravers as they seem to be able to engrave finer detail than I can achieve with a high speed spindle and they have pretty reasonable prices for say a 30W machine....
