Clogged print

Posted · Clogged print

I have an S5 with material station and air handler (only a month or so old) I have been printing with great results since I got it but yesterday I was continually getting er61 or er65s. I would remove the stuck material and try again with the other print core and it happened again... it seemed like the material was getting heated and expand and then not fit back through the boden tube on retraction.


after a few more tries I was able to print a calibration cube successfully so I ran another print last night and then I woke up to a huge mess, essentially a solid block of plastic that pushed open the fan shroud... any idea what is going on here? and how do I clean this up, heat gun?


I have been having these issues with, UM-CPE and UM-Tough PLA

and I am just using the "Fast .2mm" or "Normal .15mm" presets.


Thanks for any help.

    what you got is called "head flood" (please use search function for further infos).


    see for example:



    As your printer is pretty new (warranty), first step should be contacting your reseller.
