Filament Runout Sensor - Native Marlin - Chris's Basement

[@247hinkey]

Good evening Chris - finally got this working - forgot to mention I was using Marlin 2.0 bugfix version. Anyway had to use Z_MAX axis pins with a change to the pins on Ramp 1.6+ board to "#define FIL_RUNOUT_PIN P1_28" (not servo pin 4) currently using Octoprint and works ok. P.S removed #define Z_MAX_STOPEND (//). plus changing #define FIL_RUNOUT_INVERTING true FROM false. Thanks for your help and great videos. Your a star for for allowing people like myself (greenhorns) to understand and learn this system. :)

[@ChrisRiley]

So happy that my video helped you and that you got it working.

[@dphillips9641]

Awesome Dennis! I am glad you got it working! A great feature add on to any 3D Printer.

[@paulraggett7837]

Clear and easy to follow. Once again you have created the go to video for the subject. Thank you and I wish you much success with your approach. I am eager to understand the software and look forward to learning more through your excellent videos. Paul

[@ChrisRiley]

Paul Raggett Thanks a lot Paul! I am very glad the videos are helping others.

[@Caverntwo]

Nice video again, Chris! Very easy to follow. I'm so happy that I've been using them for a while now, saved me like 3 prints already (you know, old filament likes to break...)! On my dual-extrusion Anet A8, I just ended up using the Z_MAX_PIN, as the SERVO_3_PIN was already used by the fan-extender.

[@ChrisRiley]

Thanks! Yes, I have been using it to use up some of the sort pieces of filament I have laying around. Thanks for watching!

[@3dmjp]

Againm another helpful tutorial. I install the same sensor on my custom built Delta, with the SKR 2.0 board and Marlin 2.11. Installation was simple, but I had a couple of odd issues. 1. Even though enabled in firmware, I had to M412 S1 and M500 to enable the sensor once loaded to the board. 2. The active Sensor interferes with auto bed leveling, but not with auto calibration. Disabling the sensor, allowed me to auto-bed level. Then I simply reactivated the sensor for printing. This may be just me, but I thought it was worth mentioning.

[@ChrisRiley]

Thank you for your insight!

[@Joe-Skynet]

Wow what a coincidence!!! My filament sensor just arrived a few days ago and I was wondering what to do. On the printers web page they say to connect it to the servo that's closest to the SD card reader on my board but it's always better to see it being done before trying it myself. Thanks again talk about sinchronicity :)

[@ChrisRiley]

JOSEPHPORRO Awesome! I got this one done just in time! :) Thanks for watching!

[@Joe-Skynet]

Chris Riley my capacitive sensor for autobed levelling is on the way also. I was wondering if you could do a video on how to set that up. Many many thankyous

For compatibility with Octoprint I recommend to enable HOST_ACTION_COMMANDS - so Octoprint would be aware that M600 was triggered and printer is paused/resumed.

[@ChrisRiley]

Thanks for the tip!

[@SinaShahsana]

There is another Z style you didn't mention. Voron switchwire style which they clam is the best, it doesn't go out of sync and it doesn't wobble.

[@ChrisRiley]

Belt Z has been around for a long time, but that is a whole different subject.

[@s3rkanAGA]

Thanks Chris. I have done all the code changes and marlin works well except I dont have the menu in 8:40. After loading, it immediately returns to printing.

Great explaination, nice, simple, and easily explained - thanks, seeing how this seems to tie together in marlin, it also has me wondering if is possible to add a simple menu item that runs a small gcode routine to assist in manually levelling the bed

[@TheAbs441]

Hi,Chris, I finally figured it out about the runout sensor.It was pin 11. But I still have a problem with the pause parking , to change the filament.When it parks it stays ontop of the print and when I change the filament ,it starts coming out on the print. Thanks.

[@ChrisRiley]

I recall someone else having this issue, don't remember the fix. Make sure of these settings. Configuration_adv.h make sure this comment is removed: #define PARK_HEAD_ON_PAUSE Configuration.h make sure nozzle park comment is removed. #define NOZZLE_PARK_FEATURE #if ENABLED(NOZZLE_PARK_FEATURE) // Specify a park position as { X, Y, Z } #define NOZZLE_PARK_POINT { (X_MIN_POS + 10), (Y_MAX_POS - 10), 20 } #define NOZZLE_PARK_XY_FEEDRATE 100 // X and Y axes feedrate in mm/s (also used for delta printers Z axis) #define NOZZLE_PARK_Z_FEEDRATE 5 // Z axis feedrate in mm/s (not used for delta printers) #endif

[@Bajicoy]

hurray! been printing a ton so I need this haha

[@ChrisRiley]

Ha ha! That is exactly why I did this video. I was standing at the hang printer late one night waiting for the filament to run out, then I decided, this is ridiculous. Time for a filament sensor. Thanks for watching!

Hi I've been able to config my skr1.4 turbo because your tutorial was very useful, now because I use vsc do you have any videos regarding using this runout switch on my skr1.4 turbo via vsc or would it be exactly the same principle? I'm about to start working on my second printer and want to use the same switch you have in this video as I have them

[@ChrisRiley]

It will be exactly the same, just use the e0 detect pins.

[@pavelgrishin]

I'm using a simple button (without PCB). Using 2 wires (ground and signal). The program either stops continually (normally close) or never stops (normally open). IDK what is wrong with it. Using RAMPS1.4

The switches can go into a floating state. Try adding a pull down resistor.

[@ImaginationToForm]

Hello. Is there a way to lock the X and Y axis but keep is so we can still load filament? When I do a M600 on my Robo R1 Plus I can accidentally move the head messing up the print when the printer restarts to print.

[@ChrisRiley]

I am not sure about the version of Marlin the Robo runs, but in the newer versions there is this feature. In M600 that takes care of this. In your version of Marlin you might be able to set #define PAUSE_PARK_NO_STEPPER_TIMEOUT // Enable to have stepper motors hold position during filament change In your version of Marlin you might be able to set some of these options to help. #define DEFAULT_STEPPER_DEACTIVE_TIME 120 #define DISABLE_INACTIVE_X true #define DISABLE_INACTIVE_Y true #define DISABLE_INACTIVE_Z true // set to false if the nozzle will fall down on your printed part when print has finished. #define DISABLE_INACTIVE_E true

[@ImaginationToForm]

Oh thanks. Ill look for those and or download newer version.

[@ImaginationToForm]

Meh I had everything but PAUSE_PARK_NO_STEPPER_TIMEOUT in the firmware. Guess I'll need to download newer and configure for Robo.

[@olivergreaves5665]

[@ChrisRiley]

Thanks!

[@UncleRons_3D_Pub]

Great video, Chris. If used on a Bowden setup, should the retract distance be equal or greater than the length of the Bowden tube plus length thru the hotend, to push the filament all the way back out?

[@ChrisRiley]

Thanks Ron! I haven't played with this yet, but I think you are correct. These 2 M600 settings are what you would want to change. #define FILAMENT_CHANGE_UNLOAD_LENGTH 100 #define FILAMENT_CHANGE_LOAD_LENGTH 20

[@247hinkey]

Good evening Chris - Everything now working except every time I start a print it is wanting to change the filament prior to print. Any ideas - Thank you in advance.

[@ChrisRiley]

Does it allow you to continue?

[@247hinkey]

@@ChrisRiley Hi Chris yes it allows me to continue - The problem seems to be on startup - once a print is done and another one setup without restart there are no issues.

[@ChrisRiley]

@@247hinkey Interesting, seems like the sensor gets triggered or something. Try turning on the pull up in the code.

[@bumbarabun]

I always have issue to remember running M119 command - filament sensor triggered is filament in or filament out? And it seems nobody of marlin authors bothered to document it. DAMN.

[@ChrisRiley]

I didn't learn that m119 would work until years later.

[@bumbarabun]

@@ChrisRiley I see, but the worst part even after you realize it is difficult to realize in what state filament sensor should be. Configuration.h says, that by default it should be HIGH when filament present. But HIGH is it triggered or open? And it is damn impossible to find anywhere (maybe I cannot) what it should be. I even created FR request on github, to put that information in Configuration.h

[@ChrisRiley]

@@bumbarabun It depends on the sensor you use, with a micro switch you can can it just by switching the wires on the legs. Not sure on the optical endstop, there are a couple different ones.

[@bumbarabun]

@@ChrisRiley sorry, maybe I did not make it clear. It is not difficult for me to switch logic, either by wires or flipping that flag in firmware. I find frustrating that you have to run test print to determine that if your logic is correct. It would be quite easy tune if they say "you logic should be that when filament is present M119 should say filament: TRIGGERED", but that information is nowhere to be found. In Configuration.h they say "firmware assumes that sensor value is HIGH when filament is present". But HIGH is that triggered or open? And that drives me nuts - it is so easy to provide that information and it would be so valuable and nobody bothered. And looking around so many people confused by it.

[@dustykatz9504]

Good morning Chris. Thank you for publishing these excellent tutorial videos. I am fairly new to 3D printing and have been upgrading my printers, right now my Ender 3. Installing an MKS Gen L board with 2208 stepper drivers. I have been binge watching your videos. I made the changes in Marlin for the filament runout sensor, per your instructions but when I verified the changes the following messages showed up: static assertion failed: ADVANCED_PAUSE_FEATURE is required to use M600 with FILAMENT_RUNOUT_SENSOR #error¨FILAMENT_CHANGE_UNLOAD_LENGTH must be less than or equal to EXTRUDE_MAXLENGTH I am running Marlin 1.1.9 I went through your tutorial again step by step to verify I did it correctly, think I did. I am unable to find EXTUDE_MAXLENGTH anywhere. Might you have any thoughts or word of wisdom? This would be a 3 coffee cup response. Thank you.

[@coolt5]

I want to ask you if you have any idea? I have JGAURORA A5 and i broke the filament sensor pins on the tft screen borde. So i need to plug that sensor to the mks gen L motherboard. Now i fallow your video all is good but when the sensor deducts the filament run out its pause the print but the TFT screen shows nothing about it. And i cant resume the print. I change definition of it in pins_RAMPS.h as #define FIL_RUNOUT_PIN 2 or 4. Although the filament sensor works that way and pauses the printer successfully, the touch screen ignores it.

[@ChrisRiley]

Yeah, it sounds like it was using the TFT filament feature to trigger it before. Now the TFT will ignore it. About all I would know to do is swap to a different screen. I don't even think there is a gcode command you could send it.

[@DerekMatthews]

Chris, I am sure you have done a video on this but if I take to long in changing the filament on the M600 command, the motors will disable them self's and it will lose the height on the Z. So when I replace the filament it will not go back to where it left off. Can you point me in the right direction on sorting this?

[@ChrisRiley]

Hey Derek, thanks for watching. Yes, check out M84 or check these out in configuration_adv.h #define DEFAULT_STEPPER_DEACTIVE_TIME 120 #define DISABLE_INACTIVE_X true #define DISABLE_INACTIVE_Y true #define DISABLE_INACTIVE_Z true // set to false if the nozzle will fall down on your printed part when print has finished. #define DISABLE_INACTIVE_E true

[@emilrodriguez5696]

You can probably get away with it by using individual sensors (limit switches) for each filament and wiring the limit switches (using the Normally Open pin configuration) in series. If any of the filaments run out, the limit switch will open the circuit triggering the filament run out signal. I hope this helps you.

Can I use them on a printer without heated bed ? Do I need a MOSFET board or some DC-DC convertor ? Thanks !

[@ChrisRiley]

If you don't use a heat bed, anything over 5A should work. You could probably run at 15v, but I wouldn't recommend it. You could probably use something like a 7812 voltage regulator to get you down to 12v. If I run across one of these supplies I will look into it. Thanks for watching!

@@ChrisRiley Yes I can see it triggering and open status in M119 reports It is working in the terminal but when I start a print it goes straight into filament runout warning and pauses the print with or with out filament in the sensor. My wires are closest to the drivers Black green red If I was to record a vid on the process for you to see what is happening what would you need to see

[@ChrisRiley]

@@shellyrobinson5806 I think the wires are wrong, it should be red closest to the driver, then black, then green.

How can I do this in marlin 2.0? I have no pin_ramps.

[@ChrisRiley]

All the settings are in folders now. I suggest moving to VScode. These are the files you're looking for Marlin/src/pins/ramps

Hi, I try to do it on my Ender 3 pro with Raspberry PI 2 Model B - NOT WORKING Why? I do all step by step - Someone can help me pleaseee

[@ChrisRiley]

What pins are you using to hook the sensor up?

[@waydaminute4900]

Hi Chris, thanks for the video. My sensor was advertised with black red and white wires. Easy enough, black ground, red hot and white signal. Problem is the sensor they sent me had blue red and green wires! I cant find a pinout or wiring diagram anywhere for this sensor. www.amazon.com/gp/product/B07F65TXGS/ref=ox_sc_saved_title_7?smid=A26ATEC08S9EFM&psc=1 Any ideas how i can get it installed without damaging my mks gen 1.4 if i guess wrong and have wire(s) inverted? Thanks

[@ChrisRiley]

Is the case on that sensor easy to open? It's probably marked on the PCB I would guess.

[@thejavaman53]

You sound like the guy from "The daily dose of internet".

[@ChrisRiley]

Ha, interesting, I don't know that channel but I will check it out.

[@thejavaman53]

One advice though. Don't overdose.

Hey! Don't know if you know but the Prusa i3 indirect runout filament sensor is on the market, why still use the clasic mechanical endstop ? link here: goo.gl/WxB7gp It does not work with ramps 1.4? I would like to buy it. Can you review it? or just post a comment here if it works with adruino mega + ramps 1.4 or re-arm + ramps 1.4.

Really I love your well explained videos, I Have a problem in Einsy board i build my own 3d printer using Einsy board, And I use Marlin-i3-MK3 firmware (github.com/prusa3d/Prusa-Firmware) but how can I install Power panic in my printer I have mk3 power panic PCB board but how can configure in my firmware? sorry for my English.

[@ChrisRiley]

That is a great question, but I have no clue. Do you have the same PSU with the wire Prusa uses?

[@PatelMayankG]

@@ChrisRiley yes I have same PSU with wire.

[@ChrisRiley]

@@PatelMayankG It should just work then. Same firmware, board and PSU.

[@FunKing3d]

That just seems too easy to not use it!

[@ChrisRiley]

Fun King 3D Its one of those things I have wanted to do forever, but never took the time to. Now I think it's a must have upgrade.

[@FunKing3d]

Well I am definitely going to hop on that.

[@3dgussner958]

Again great video, if you have an original Prusa MK2/s with/without MMUv1 you can try my modded firmware github.com/3d-gussner/Prusa-Firmware/releases/tag/v3.1.0-001-HFM . It can be configured/en-/disabled via LCD menu.

[@ChrisRiley]

Thanks! Awesome firmware man, thanks for sharing. Nice work!

[@markgreco1962]

Chris I Remixed the Filament sensor And added a link to your vid on Thingiverse. Hope you don't mind the link www.thingiverse.com/thing:3326077
