In this video I show details on how I installed an endoffilament detector on an Ender 3 V3 SE. According to their literature it should work with all Ender 3, Ender 3 Pro, Ender 3 Max, Ender 5 Plus. It should work with other Ender 3's as long as they have the 32 Bit V4.2.2/V4.2.7 Motherboard, although you might have to upgrade the firmware on other Ender 3 models. Check with your model's papers before you order an endoffilament detector. I purchased the detector from Amazon for $15.
