Laser Engraver Forum

Hi there - can you please confirm what size lens to use with the HR laser head? Is it the same 2" (50.8mm) lens that is used with the standard head or something else?

Also - can you provide suggested settings (power, speed, and interval) for achieving good results with the HR head on wood?

Thanks!

Good day!

Yes,the HR laser head is used with 2'' lens that is used with the standard head,but there're two 2 " lens are installed inside.

For the HR photo engraving,you should find a high resolution image or picture first.
How to set the picture on the software,please go to below link.

And the setting(power, speed, and interval) ,i will suggest the power 15% to 25% (according to the laser tube),speed 500mm/s and interval 0.06(DPI 400 ).

Hope it can help for your work.

By the way,please improve your profile for machine info so we can check your machine information.

Thank you for your response.

Can you please show how the two lenses are to be installed in the HR laser head? Are they stacked on top of each other? This is not clear to me - thank you.

I have a Nova 35 130w - I could not find where to add my machine's serial number to my profile.

Thank you - Dan

Good day!

Sorry for my late reply,just back from the Lantern Festival.

For the lenses in the HR laser head,you can take out them to check and the direction of installation for two focus lenses please refer to below picture. About the problem from the profile,i will check and tell you later.

Hi Ben - thank you. That is how I have the one lens installed (it is facing the correct way).

My original question still stands - how do you install two lenses? Do you stack them on top of each other?

Thanks

Good day!

They are stacked with two fixing rings.see below.

Excellent - thank you!
