Cheap limit switches, free brackets and a free guide for your Sculpfun S9 (and most other DIY laser engravers wit a 2020 extruded aluminum frame): [ Ссылка ]

There are some vultures on YouTube and eBay that offer home made and shoddy looking limit switches for ridiculous prices to people that don't think they can make or install these themselves. But they are only around four bucks in parts and take about 10-15 minutes to install. No soldering or technical know how required... The guide you'll find on the other end of the link enables anyone to do it themselves in 8 easy steps...

The brackets in this video are the versions with integrated drag chain mounts [ Ссылка ]

Parts I used:

Honeycomb work bed:
(Made out of aluminum so not magnetic, you'll have to use hold down pins. Steel ones are twice as expensive)

Air pump:
(I ordered the ACO-318 but I've read the ACO-208 has more than enough power, is not as loud and a lot cheaper. Never mind the plug adapters just pick a random one, the default plug is US as pictured)

Silicone air hose:
(Pick any color and length you like with an outer diameter of 6mm and inner diameter of 4mm. Just remember that there's a limit to the length before you start losing pressure. I got 3 meters (around 10 feet) and have no issues)

Limit switches:
(You get a set of four with four but need only two)

Drag chain:
(It's a bit more expensive shipping to the US than shipping to Europe, don't know why...)

Extractor fan:
(Cheapest 100mm/4" fan I could find with decent air flow. Don't know if they're available in the US but there are plenty of equivalent inline fans to be found online:
