TPE stops extruding after few layers

[vladoportos]

Hello,
I have Felix 3.1 Felix printer, direct feed. I'm trying to print TPE flex material, when I cut and insert the filament and feed it manually via control it go through just fine, extruding without issue.

I start to print, slow, and it continue extruding and everything is fine until maybe 5 to 6 layers when it simply stops.... the feeder is spinning but not grabbing the filament and pushing it further. I think that that maybe the filament gets warm before its go down and won't grip or something... I can't explain it... it always work for fine manually and for couple of layers but than nothing...

Anybody have Felix 3.1 printer and successfully printed flexi materials ?

I've used a felix 2.0 and Ninjaflex. The 3.1 supposedly comes with a better drive gear for printing flexible filaments. I learned a lot recently from the best practices mentioned on S3D's material guide for flexible plastics and have been getting much better end results.
