Is there a setup tutorial for the Linksprite Laser head?

[rseijo]

Hi, I have the Linksprite CNC with the optional Laser (pls see below).
Does anyone know how to properly setup, adjust and or focus the Laser for Etching vs Cutting?
I have tried to locate instructions for this laser with no success.

I will be grateful for any guidance on this...

Thanks!
Ralph

A perfect laser focusing is necessary for cut and engrave too, specially with low power laser. This is what I do when I nedd to focus my laser: - Put a piece of black cardboard on the engraving surface. - Turn on laser at the lower available power M3 S30 - Do a small move G1 X1 F100 - Now focus by hand, rotating collimation gear to obtain the smallest dot. Try this sequence Diego

Ps: always wear safety glasses when near look to focus point!

Diego, thank you so much! I will focus the laser as you recommend. And yes, laser safety glasses!

Thanks again

Diego, Being that the Linksprite CNC has a movable Z axis, is there a specific height the that laser should be at for focusing?

Thanks

I dont' know, I have a different laser and my CNC is 2 axis only, no Z.
