Extruider motor stops moving

Posted · Extruider motor stops moving

So, after two and a bit weeks of (mostly) sucsessful printing, i've encountered another issue. for some reason the stepper motor for the extrusion stops moving near the end of the print. I noticed this on multiple recent prints such as the (shorter) screw print of http://www.thingiverse.com/thing:8796 and other objects about as hight (but with diffrent mass (as far as that pertains with 20% fill)).

I checked the gcode for any anomalys in the file, but there dont seem to be any.

I just noticed the gears are still turning, but about as slow as the hour hand on a clock (i.e. its only visible if you look at it for a while).

Anyone have any suggestions?

I plan on switing the extrusion motor driver with one for an axis to see if that may be the issue... but other then defect hardware I don't have any Idea what it could be. (is there any sort of garantie for the mortors?)

attached is the gcode... maybe someone will find something unusual in there... though I doubt it, since i did re code it three times.

Thanks

Note: I switched the stepper drivers and the extrusion still stops. so the issue is either with the motor or the gcode.... hopefully?

    Today I tried printing some Gcobe that I spliced a few weeks ago (right after I finished building the um) and the issue is the same, which proves atleast that the gcode is not the problem.

    so if it is not the driver or the gcode that leaves the controller board or the motor it self

    does anyone know if there is a way to test the motor with out switching it out?

    how do I controll the second extruder slot via gcode?

    this time I printed the calibration pyramid, and watched the extruider motor the entire time. It seemed like it simply got weaker up to about the middle of the print where it just stopped alltogether (including retraction). I took pictures of the results...

    You might try swapping your Pololu drivers to troubleshoot and see if that's the issue... Make sure you have completely disconnected the power before swapping them!

    thanks for the suggestion, though I have allread tried that (see above). I wanted to switch the motors, but I notice that the extruder is not completely cicular, so that isnt an option :(

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
