Extrusion issue TPU 95A with Anycubic i3 Mega

Posted · Extrusion issue TPU 95A with Anycubic i3 Mega

Hi, I tried for the first time today to print TPU, but i got an issue. 

The filament extrusion isn't constant. It print sometimes just few drops then continue normally, and then some other drops, etc. Most of the time, it just print tiny drops instead of a continuous line.

My filament is new, I opened it this morning and it was sealed. I already print ABS, PETG and ABS, and everything was fine. I changed my nozzle and changed several time my temperature (from 200°C to 250°C by increment of 10°C), but doesn't solve my issue. I  also print at 20mm/s and i use Cura

I use an Anycubic i3 mega. 

Heres the link for my filament: https://www.amazon.ca/-/fr/SainSmart-Filament-flexible-pour-imprimante/dp/B00TI3JUTM/ref=sr_1_1?__mk_fr_CA=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=SainSmart+TPU&qid=1578253531&s=hi&sr=8-1

Mod I installed: https://www.thingiverse.com/thing:2672773

 

Any help is appreciate thank you!

    I get the same, or worse, on my um3.

    I am also very new to TPE but so far only thing I can do to prevent this is cleaning the nozzle before each print.762034080_IMG_20200103_468572.jpg.b2809eb81fd5e457bf84f96f0b08531d.jpg
