My Extruder is Clicking. Is it Clogged?

Question: "Everything seemed good on the X, Y, and Z axis. I was having trouble extruding this time. It seems the E-motor is not turning. I hooked up another motor to it and when I send commands to it it seems to just click in the same spot. As if it moves one step forward and then back to where it was before.

I tried Cura and Repetier just to make sure it wasn't something in the .ini file.

Everything seems to be good this time around except I can't get filament to extrude."

 

PB Response: 

1. Uplug extruder motor from E MOT connector

2. Plug in another motor into E MOT

3. If problem persists please your board may need to be replaced

4. If problem goes away your motor may need to be replaced

    I'm having this issue but it it stops if I lift the wire bundle up an inch or so and will start again as the wire bundle sags. Seems to be poor cable management.

    I have seen this problem happen with ninja flex on my printer, I assumed the motor needed more torque (current) but did not yet have a chance to test this.

    I'm also trying to track down the source of this issue on my machine (Metal Plus, single extruder). Not the normal clogged clicking - the E-motor just wiggles back and forth on the same step position (even trying to freewheel it with no filament). Motor shaft turns OK by hand when power is released.
    I have a replacement motor on order to see if that's the issue.

    Having the exact same problem. Sometimes it will extrude smoothly for a while, then it will start clicking again. I end up with mostly dotted lines even when printing 20 brim lines.

    I'll try reconnecting the cables as suggested. Kind of disappointing as I just got this metal plus delivered today; it printed the 3mm cube fine, then the clicking started!

    Has anyone solved this issue?

    I just received a brand new Metal Plus that printed flawlessly for 5-6 hours and is now clicking?

    ------------------------------------------------------------------------------------------------

     

    I've had a simple metal that has worked flawlessly for nearly two full years and just started clicking recently.  I ordered a replacement motor and it still seems to do this.

    I've tried reducing the spring tension on the extruder arm which helped a bit but has not 100% cured the issue.

    Here is what i was thinking:

    Q: Was there too much resistance in the extruder from heat being to low?
    A: Apparently not, i raised temp to 230 and problem still occurred.

    Q: Was the extruder clogged?
    A: Apparently not, i took it apart and it seemed fine. (never had a clog in two years and hundreds of hours printing)

    Q: Is the board finally going bad?
    A: Can't be sure, but it seems unlikely since the brand new metal plus is now doing the same think after only a few hours of printing

    Q: Is the board delivering a sufficient amount of amperage to the stepper motor?
    A: my experience with my CNC router leads me to believe that this could very well be the issue. (This clicking seems more frequent when the motors are hot. My guess is that the internal resistance in the stepper is probably rising and reducing the motors torque)

     

     

    If anyone has solved this issue please let me know asap! this is a real bummer.

    I shot a video of my original simple metal: https://youtu.be/ZKfvSjoyQbI

    I will be shooting a review of the Metal Plus as soon as I get this issue sorted out.

    Thanks,
    Jason

    Jason,

    I ended up cycling the power on mine, and the issues I described were resolved completely and didn't resurface. I also think there might have been some ABS left in the extruder from test prints, so I pushed through some PLA to try to get that out of the system, but I'm not sure about that.

    Just in case it's relevant, I'm using a raspberry pi with octoprint as the host.

    Hope that helps!

    A couple of suggestions on a "clicking" extruder in the video below.  The problem usually stems from one of two issues.

    • Wire fatigue in the extruder motor - solution is to replace the motor
    • Clogged hot end, likely in the nozzle - solution is to replace the nozzle/tip

    See video here: https://www.youtube.com/watch?v=APlYNjQuJ9E

    Hope that is helfpul :).

    I have a simple model thats only a few months old and it has just now started to show the jogging motion described in the video https://www.youtube.com/watch?v=APlYNjQuJ9E

    I cheked by switching the cables and the motor is shot. This is truly supposed to last longer than a few months right? Right?

    How do I go about getting a replacement motor for the faulty one you guys shipped with the kit?

    This printer is quite vital to my work so I would appreciate a quick response.

    @Hallgrimur, sorry to hear of the trouble.  I have created a ticket for you, using your post.

    Generally, extruder motor wire lasts longer than a few months on the Simple.  We certainly see greater longevity in our assembled models.  However, if the wiring was zip tied too tightly, it can create excessive stress on the cable - resulting in premature fatigue.  

    Our support team will help you find a way to get up and running asap!

    thanks,

    My machine's clicking issues were completely obliterated after upgrading the Ubis 13 & standard extruder -- to the Ubis 13s & Gear Head extruder! The added investment = relief in my case -- no more slipping or sludgy filament to click, slip and gum up the works. Thanks a bunch for making these upgrades available Brook... out of all my 3D printers, my Printrbot is now by far the most consistent, deadly accurate and most importantly -- favored of all my machines!
