UMS3 Solex hardcore stringing and oozing


Recommended Posts

Posted · UMS3 Solex hardcore stringing and oozing

Hi all,

 

I recently bought a Solex hardcore, the first print with a 0.4 nozzle were perfect.

I adhered to the temp settings for the first hours and only printed with PLA.

 

Now after a few days the print became very stringy and it seems like the nozzle leaks. The nozzle is on thight and is changed with the nozzle change tool as recommended.

I changed the nozzle yesterday to a clean 0.4 and same issue only after 8 hours of printing (PLA 205°C).

I have played with the temp settings, lowered 10° in steps without any result.

 

Anyone an idea what I'm doing wrong?

See pictures

    Just now, JASON128 said:

    Dry your filament?

    Filament is stored in drybox with for the moment 34% humidity

    It can be ofcourse, but it would seem strange. Especially I have this with both PLA and PETG

    Will do, it is idd something quite easily to rule out.
    But just printed a stringing test with retraction of 2mm instead of 6.5mm (default cura) and the towers were perfect. So I'm thinking that retraction has a lot to do with it, the solex cores have 2 holes instead of one in the core.
