Filament runout protection only protects against the filament running out.. There are other situations that create jams and clogs tha will also cause a 3D print to fail. The Bigtreetech smart filament sensor is capable of detecting these problems and saving your prints.
This video is a guide on how to set the sensor up to work flawlessly with Marlin and the factory LCD controller. It also covers how it should work with Octoprint and the BTT TFT touch screens once updates are available.
UPDATE: Octoprint plugin: plugins.octoprint.org/plugins...
The testing hardware for this guide was an Ender 3 Pro, SKR mini E3 V2.0 mainboard and BTT TFT35 touch screen. This guide was a Patreon request. Two smart filament sensors were purchased with my own money. All opinions expressed are my own.

Phenomenal timing. I was looking at these, but couldn't find an explanation on what this actually did. Thanks!

@ixiwixi 3 года назад

This works perfectly with Octoprint; enabling advance pause and emergency parser is all it takes. I've been running this setup on an Ender 5 Pro with an SKR 1.4T for months.

@ScottFegette 3 года назад

brilliant insight and super-timely, as I was just starting to enable a switch-based runout sensor for my E3Pro/BTTe3v2 rig- this is a waaaaay better solution. thanks so much!

@greggcaplan3926 3 года назад

Omg thank you I thought I was going crazy. I tried everything with this sensor and I do have a Raspberry PI with Octoprint and the BTT TFT50 v3 and it didn’t work. I bought the sensor through Amazon and sent it back after a week of frustrating code compiling . I hope BTT fixes this soon and I will try it again.

@HemiDad1963 3 года назад

This is a great improvement for my printer. My filament always breaks above the stock runout sensor so the switch never turns off.

@williambachmann8842 3 года назад

Thank you. I'm running Octo and a Mega Zero. You saved me purchasing something I can't use.

@looxonline 3 года назад

I use it every day with Octoprint. Works flawlessly. As others have mentioned you need HOST_ACTION_COMMANDS and HOST_PROMPT_SUPPORT to be enabled in config_adv.h. On most configs these are enabled by default. The only issue I've noticed with the sensor is that over time filament dust and other fine particle contaminants can build up on the IR tx and rx and this leads to false triggers. Easy to fix. Unscrew the board and give them a wipe using a cotton ear bud. Make sure that they are pushed close together when reinstalling so that the rx can still detect the tx.

@CMDRBlueeagle66 3 года назад

Had this sensor for about a year. Very good. On my Biqu B1 I have moved the sensor to the mainboard as I mostly print in Marlin mode. However I would like to see support for this sensor so it works with the TFT and regardless of where it's connected.

@alanjones3514 3 года назад

Thanks for the video and thanks to commenters saying it does work with Octoprint. Just ordered one. Looks good.

@twinklingwater 3 года назад

The remark regarding "not working with octoprint" is wrong. I run this setup and it works fine. Marlin must be compiled with HOST_ACTION_COMMANDS and HOST_PROMPT_SUPPORT as well as ADVANCED_PAUSE_FEATURE. The host_prompt messages the interrupt to octoprint, which causes it to wait for the printer. I think this is mentioned in the official setup guide, but I may be mistaken on this one. It is required anyways when you use the filament-change-command in your prints. In theory it should be possible to remove the requirement for the LCD. When Marlin detects a filament runout situation, it executes the FILAMENT_RUNOUT_SCRIPT. By default this is merely a "M600" command. It should be possible to execute host-action-commands instead. Afterwards, the filament change must be handled by the host. I have not looked into this, and can't tell whether or how well this works.

@CMDRBlueeagle66 3 года назад

With the host commands in new Marlin I was hoping this would allow the TFT(in TFT mode) to work with the sensor when it's plugged into the main board. But no. The printer correctly pauses but the TFT screen just carries on like nothing has happened 😖

@TeachingTech 3 года назад

Thanks very much for the correction. I've pinned a similar message to this with the details.

Michael I finally got the BTT Smart Filament Sensor to work on my Ender 3 Pro with a Creality 4.2.2 mother board!. Here's a summary of what I found out All the firmware changes that were described work , but for the Stock Ender 3 Pro 4.2.2 motherboard there are a few important differences; 1) The Creality 4.2.2 mother board pin "FIL_RUNOUT_STATE" has to be set to HIGH not low. 2) The pins on the motherboard PA4 plug where the sensor plugs in are, left to right; "Signal-Ground-Voltage" the sensor I installed had the ground wire with a long white dash on it and the voltage wire had little "+" signs on it. The signal wire had nothing. So far I have run about 6 hours of prints using it and it checks out perfectly. I really appreciate your efforts to "teach" us how to modify our printers, I've got mine setup with tis runout sensor and a BLTouch, so its simple to get good prints.

Also have a bl touch all set up good to go but yeah, need to get the filament sensor 2.0 working its all installed but wont do its job!

@MrBodzinek Год назад

If you are having trouble with TFT 35 try inputing M412 D7 via terminal (in my case when flashing firmware, the filament runout distance was not set to 7mm, it worked perfectly after that)

@johnm.gerard1718 2 года назад

I have the Ender 3 Max modified printer. I find the stock sensor without taking it apart the filament just will not feed into the sensor very easily. And I don't want the frustration when trying to load filament. Plus having a filament jam sensor built in is a bonus.

@billbrown1877 3 года назад

I am using the micro swiss direct drive extruder on my ender 3 and the E3 min v2.0 controller + TFT35V3 display. this extruder uses the bowden tube on the input to the extruder allowing the smart filament detector with a modified case to be mounted where the original extruder was mounted. This allows retractions to be monitored as well. I have no problems with octoprint as as well. TFT35_v3.0.26.x Dated Sep 27th in graphics mode, displays the popups for filament parking, loading and purging. Also Octoprint indicated the same popups. I am using merlin 2.0.6.1.

@bernardthongvanh5613 3 года назад

I have SKR 1.4, BigtreeTech LCD and Smart filament sensor. I have connected filament sensor directly to SKR 1.4. I mainly print from octoprint and use touch screen just maintenance. While printing I put lcd to marlin mode so filament sensor events can be handeled. For me sensor works just fine and I don't really need octoprint to handle it as marlin seems to handle pausing and while fixing the issue I'm already at printer so I can continue from marlin mode lcd. I wish it could be used from touch mode when connected directly to skr 1.4

@accreditationmanager2878 3 года назад

Second Try. Thank you for a very informative video. I have an ender 5 plus, touch screen control. What do you think the chances of the BTT sensor working with the correct firmware changes? Also considering a board upgrade to BTT SKR. PRO 1.2 with replacement screen. From your comments the upgrade would not support the sensor at the moment. The other board under consideration is the Lerdge X, any thoughts using the BTT sensor on that board? Thanks again for great content.

@TheQBall1977 3 года назад

I was completely sold on this until you mentioned it does not work with the BTT touch screen or Octoprint. Can you just switch the interface on the BTT screen by holding the button (Marlin Emulation) for long prints? I really hope they sort it. Thank you for the thorough tutorial and guidance.

@jpolarseminario 3 года назад

Also, when using with Octoprint, the firmware on the printer will buffer sometimes several lines of GCODE. So firmware must tell Octoprint to pause too, otherwise when octoprint decides to pause, it could be too late.

@DocMicha 3 года назад

Also for those who have only a switch as filament sensor this might work with a small uC in between which gives ok as long as filament is not broken and still running.

@byronkobialko3442 3 года назад

Does it need the SKR Mini E3 board can I use it on a board that has a spare spot for a filament sensor like the CR-10 V2 board?

@rgmtb 3 года назад

My deal with these things is that I use OctoPrint so I have to connect the sensor to the PI. I've got a printer that came with a filament run out switch and I quickly learned that sending a run out alert to the printer when you're sending commands to the printer via the PI does little good 🙁

@TheNamelessOne12357 3 года назад

If it has high resolution encoder it could also be used to measure fillament diameter and adjust flow accordingly or pause printing if the diameter is too thick and that blob will definetely jam in the bowden tube or in the heatbreak.

@mareksvrcina5279 Год назад

Theoretically yes, but you would then need to find a way to determine the position of the springed mechanism very accurately. Not impossible even in a smaller package like this but it would certainly make the sensor cost much more and it would no longer be an affordable printer upgrade. :)

@ein57ein 3 года назад

Good to know... I've had multiple jams thanks to loose spools lately and was about to order one of those. Most of my printing is done via Octoprint, so I'll have to wait

@twinklingwater 3 года назад

No, you don't. Octoprint works fine.I followed the official guide and octoprint pauses when the filament runs out. The display and button on the printer is still required, though. You can test if it works by adding a filament change command to your gcode (M600). If this works, everything is setup correctly.

@RonnieLaugen 3 года назад

As far as octoprint goes, I believe you just need to enable host_commands (or something like that?) in octoprint and marlin. This allows marlin to tell octoprint to pause the print until it gives a resume command.

@ferd352 3 года назад

Yeah I'm pretty sure you're right because mine is hooked up to a mini E3 and I use OctoPrint, and it handled everything fine. At least when I was getting set up. Now I need to go and check it out tomorrow just to make sure. I do recall that 7mm was too low for my dual-gear extruder setup, and ended up at 25mm before the false alarms stopped - it's also mounted on the entry side of my Ender3Pro using this www.thingiverse.com/thing:4550063

@twinklingwater 3 года назад

I agree. My setup is an SKR1.4 with the smart filament sensor, all prints go through octoprint. I think I followed the setup guide and everything works just fine. I've even had a few situations where less filament was extruded and the sensor still detected the failure (e.g. when the nozzle pushes against the build plate). After the issue is fixed, octoprint happily resumes printing.

I installed this using the SkR mini E3 V2 and at the start of the print after the priming line it throws up a change filament and begins unloading the filament. Could this be a firmware tweak?

Marlin didn't apply the filament runout sensor distance for me on Ender 3v2, Creality 4.2.2 board. M412 was returning 0, making the print stop immediately. I ran M412 D25 to set the distance to 25mm for my direct drive setup and all is well!

Nice video Michael. Have you tested with flexible filament? My experiences this will not work because of spring that keep internal pullers (that guides filament) tight. I was not able to push tpu or other flex thrrough hole. Solution for that in my opinion is switch filament runout off for plexible filament. Apart of that I must say I agree with you - works saves a lot of time, money and nerves :) Regards!

@jensschroder8214 Год назад

I have Marlin 2.0.9 on the 3D printer. If the filament runout sensor or I send the filament change on the display, Octoprint also pauses. To do this, I have to manually release the print on the display again, then Octoprint continues. The runout sensor is connected to the printer. There are no problems with Octoprint because it waits for the OK from the printer.

@charlesbeshaw9843 2 года назад

Nice video, can see that this would prevent a lot of ruined prints. However if it was a truly "Smart Sensor" than all the logic should have been built in. It would see a break or a jam allowing it to out put a signal same as a traditional filament runout sensor(triggered or untriggered). This would eliminate all the configuration changes. That would be a true plug and play replacement for a traditional filament runout sensor.
