Goodbye Side Filament Sensors! What Good Are They?

I have seen many mods for the awful side filaments detectors.  A few have questioned their need.  I have come to the conclusion that they are worse than useless.

I replaced them with connectors only (see pic). I had already moved both detectors to one side as I feed from Sunlu S4's and I designed a part to hold 5 connectors instead.

Benefits:

1.  No more filament jams due to the detectors binding (lost 3 prints to jams in the detector).

2. Sooo easy to thread filament now.

3. Spool Join still works perfectly with less wasted filament (~80mm vs 900+mm).

4.  Works with TPU.

5. No time wasted modifying the detectors to reduce the drag on the filament.

Negative:

1.  It is necessary to remove the Bodin tube from extruder to remove small piece of filament after unloading after using Spool Join.  This is also needed if you just let the filament run out (you can still load new filament and continue printing).  This is not needed when unloading filament as when changing filaments.

I have not been able to find any other problem with eliminating the detectors.  I still use the detectors at the extruder.

I would like to hear from anyone if they know of any other reasons to keep the side detectors. Thanks.  Enjoy your XL!

Try it!

I forgot to mention that you should disable the detectors in the printer's menu.  I did not try just unplugging them.

Hi Scisok,

They are nice to have for filament runout and spool joining if you are doing large prints.  I have a dual S4 setup (here) that I made new magnetic sensor housings for (here) but you also need to modify the S4s, make new sensor housing mounts, and lengthen the cables, so it's a bit involved.  Probably not worth it for everyone.  I haven't tried my set up with TPU yet, but I bet mine are also still a pain for that.

The sensor at the extruder allows for spool joining and runout already without the side detectors.

That is true!  Just takes a few more seconds to change filament.  Definitely worth considering deleting the side sensors.  Maybe I'm just a belt and suspenders kind of person . . .
