Print head assembly rods worn


Recommended Posts

Posted · Print head assembly rods worn

Hi There


We have been having a few issues with our UM3 which has meant we've been needing to unscrew the print head a lot. so the 4 long screws that pull the whole print head together with the hex tops are failing. The hex tops are just no longer biting the hex bits we have.


Can someone help me out with where we get these as I tried UM, our reseller and am drawing a blank.


Any help appreciated

    Did you try contacting fbrc8.com?   They are U.S. based part supplier.  If they dont have it or can't get it, no one can.  They ship super fast.


    Last ditch effort would be to try McMaster-Carr, Fastenal, or Grainger.  Can determine the thread size with a thread checker or calipers, and then measure the shoulder length, thread length, etc to get the exact screw you need.

    They are M3 screws (3mm - standard thread).  With "socket cap" screw heads (although any head type should work).  You can indeed measure the length and get similar ones (threading will probably run the length but that's fine).

    Hey guys, sorry for delay in getting back to you.


    I'll go and try those places then. Sounds like I just have to hunt for a raw screw then. I was hoping there would be standard place someone else had bought them from before to make life a little easier. These ones on the UM3 seem to be very soft, the UM2 ones I have seem to wear much better?

      • 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
