Filamentive rPETg spool catching/tangled


Recommended Posts

Posted (edited) · Filamentive rPETg spool catching/tangled

Hello all, 

wondering if anyone else has similar experience and/or solution. I am running a 500g print with a filamentive rPETg on an UM-s3 and approximately every couple of hours the print stops suggesting the spool is empty. In fact the material has become lightly “tangled” on the spool and won’t feed. The material is in the outer position and I have the guide in place. 
 

im not sure if this is specific to this spool of material, or the spool type (cardboard) etc. I haven’t experienced this with UM Materials.

 

would welcome thoughts and experience. 
Thanks

    It's hard to explain in words but the end of the filament can get caught under a loop on the spool.  At that point you have a "permanent" tangle that will keep moving around the spool.  Sometimes the printer is strong enough to just pull through it but often it can't.

     

    The basic solution is to remove the spool from the back of the machine, unspool a few meters and while doing that you should be able to fully visualize the tangle and fix it by passing the spool through the loop.  Or if that's too mentally difficult, unload the filament and remove the tangle by passing the end of the filament back under the loop again and then reloading into the printer.

     

    The way to keep this from ever happening again is to NEVER let the end of the filament go.  If you let go for 1/10th of a second it can sproing like a spring and jump under another loop without you noticing.
