I’m not familiar with the Longer Laser B1 40W but I have an Atomstack X40 Pro and i love it. Easy assembly and i have never had any issues with it. I’ve heard some negative comments on the IKIER K1 Pro.

Here’s a link to someone’s comment on the IKIER

Ikier K1 pro fibre laser, not a great machine, at least mine isn’t

I bought one of these, even though there were no reviews (worth the name) out there, as I prefer a gantry system over the (much faster) galvo options out there, I have never been afraid of early adoption, and have had previously had great experiences of Atomstack products, so I sold my previous Atomstack products, and my very hard won savings and bought one.

I cannot recommend one machine over the other, but I can say that I am positively surprised by the Longer Ray 5 with 20 Watt laser. Material and processing quality are fine with the machine I have been involved in installing. Interplay with LightBurn is seamless.
My personal preference for autofocus is that I do not have or do not want autofocus on my machines. It is relatively rare that I change focus during the day and the extra weight on the X axis is counterproductive in relation to speed. (applies to diode laser) On a co2 laser with an automatic lifting table, autofocus based on a non-contact sensor will be interesting, but, …adjusting the focus without it takes me approx. 5 sec., so I’ll keep it simple.
