This video shows test of two laser optics' setups of my Inova SLS 3D Printer.
First setup includes anamorphic prism pair to correct shape and size of the laser beam and the plano-convex lens to focus it. Second one consists of fast axis correction lens embed in laser diode and Keplerian telescope to extend the beam size and to focus it
Initially it was not intended to share this video - I made it from my working video-notes. I am sorry for its the quality.

Hello...verry useful comparison.Great! May I ask a question? What is the focal distance of FAC lens?

@SLS4All 2 года назад

Hi, thanks. I use laser diode with the embed FAC micro lens. So, I can't tell you. It is from company called Laser Tree.

That's really nice what are you using for the galvo system?

@SLS4All Год назад

Thanks. I used Dragon Tiger DT-40 galvo set.

What spot size are you getting?

@SLS4All 2 года назад

It should be somewhere around 0.25mm

Hello How about the firmware to control them, please?

@SLS4All 2 года назад

Hi, we have modified Klipper FW and use it for low-level tasks (stepping, etc.). All the rest is our own solution.

@Roark98 2 года назад

@@SLS4All is it possible to share it, please? I build a cartisian-based SLS already. But I want to apply a galvo scanner instead. Thank you so much

It hasn't been finalized yet. We plan to publish it sometime during Autumn. I will announce the information about the firmware release in email newsletter and on Discord.
