Because I bought the eBox, the filament is not smooth when using it. I found a lot of information about the ebox on the Internet. Most of them are placed on the top of the printer, but I don’t want to place it in that position, and the wires and other things will hang. , so use the roller to guide. Originally, I designed another thing to install the filament detector on it (https://www.thingiverse.com/thing:6079276), but the cover will be pulled open when the filament is drawn, so I used Using this mode, I think the effect is not bad!
