UM3 - Following material overflow, Printcore enclosure won't close.

Posted · UM3 - Following material overflow, Printcore enclosure won't close.

We had a pretty big print failure here today and wound up getting a bunch of material behind the Material 1 core (AA). After we raised the temp of the print core and scraped out all the material (had to replace the print core since the wires of the print core got all gunked up and pulled out of their sockets on the way out). Got the print core in, loaded it up with material and everything worked fine. Until I went to close the enclosure. Wouldn't close. Magnets don't get close enough to make contact.

After a lot of examination as to why this was happening (we couldn't see anything), we noticed the print core hotends weren't fitting correctly into the little rubber positioning inserts under the print cores. The rubber there actually seems to have warped. I am theorizing this was from the mass of material that got caught up in there.

Any suggestions as to what I can do to fix this? Ive tried a bunch of different ways to get that rubber to fit as it does on our other UM3s but I just can't seem to get it right. seems like the rubber has become deformed. Do I even need that rubber there? Can I just take it out?

TIA

    Just take it out. It helps with airflow a little but mostly it's purpose is if your part gets partly done and is vaguly shaped like a hokey puck and then comes loose it will slide around the build plate and filament will keep coming out of the nozzle and get up inside the head.

    But if you avoid autolevel and your parts stick like hell to the glass or instead if you check your print's progress every 30 minutes then you are unlikely to run into that problem.

    I guess I would order another one from fbrc8 but print without it.

    disclaimer: please don't go after me if you ruin your head because it filled with plastic.

    I mean I've been printing for years and never had this problem. But MANY other's have had this problem (hocky puck sliding around creating massive blob that enters the print head).

      • 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
