Review on BIGTREETECH DIRECT Filament Blocking Detection by Joseph Long

Tried everything to get this thing to work on my Ender 3 Pro and finally gave up. There are a few things I don't like about this sensor, aside from the fact that it doesn't work with my printer. 1. The manual is a bit difficult to understand as it is poorly translated. 2. The sensor holds the filament very tightly and you will see this in other reviews that may require you to change your steps just to accommodate this. 3. He has no light to indicate that he feels a thread within him or that he is being fed. It's not a big deal, but it would help if I fixed any bugs. I will say that if you IM them they will contact you on the Big Tree Tech Facebook page and help you with the problems you are having and I am giving an extra star for that and only that. I hope someone who buys this has better luck than me.
