Problems with S5 pro bundle


Recommended Posts

Posted (edited) · Problems with S5 pro bundle

Got a new S5 pro with air manager and material manager.

When printing with 1 extruder got no issues. But when printing using both extruders one of them will not extrude first couple of layers.

Prime tower is On with 6mm³.


Exact problem. Both extruders are loaded and primed correctly.

Brim is applied using extruder 1.

When second extruder starts printing nothing comes out for the first layers. After it will start producing small blobs.

Rectified issue by increasing the prime volume to 42mm3 on both extruders.

Problem is not extruder dependent as I reproduced problem by swapping extruders settings.

Meaning doing brim with extruder 2. With brim on extruder 2 problem is reproduced on extruder 1

    I have an S5 but I don't have the material station so I'm not certain but this sounds familiar from quite a while back (maybe a year) when a new firmware version fixed this or something similar.  So make sure your firmware is at least no more than a year old.

    This happens to me sometimes when the material is in that ready position, a few cm back from the head. It doesn't reprime the print cores when it is in that position, so any ooze during cooldown or heating up is lost material volume that is unaccounted for and results in an empty head at the start of the print. Bizarrely, on the first layer, it prints the prime tower after the part, so you end up with missing extrusions. I just enable the prime blobs to make sure I've got the heads primed and the problem is taken care of.

      • 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
