Hi, I bought a Sculpfun S30 Ultra 22W. This is my third laser. Unfortunately, the included air pump with 30 L/min flow seems too weak – it scorches small elements.
I connected an Atomstack F60 pump (60 L/min) and the results are much, much better. However, this pump isn’t compatible with the laser and doesn’t work in automatic mode in LightBurn.
I’d like to replace the stock pump with something that has at least 60 L/min flow and can work automatically in LightBurn. Can you advise me how to do this?
As shown in the link above, you can add a relay to the automatic output of the laser and connect any pump (or compressor) you like.
Though in my experience, the compressor of the S30 Ultra is usually quite sufficient. But it might depend on the use case and circumstances. Make sure to place the pump outside the enclosure, of course
I just wanted to say I’m glad I saw this post! The link to the relay info was exactly what I needed to get my air assist compressor replacement up and working with a relay setup I was trying to figure out. It just happens that I have an MKS board driving a LaserTree K10 Mini and it looks like I will be indeed able to hook up my old airbrush compressor via a relay to utilize Lightburn’s automatic control of the air assist. Huzzah! Increased airflow with less noise AND AA automation so I don’t scorch light engrave whilst still getting clean cuts!
