TPU not Working with A30M

[Deadeye]

While the A30M doesn’t specifically say it works with flexible TPU, I found the extruder stops feeding it. I tried modifying the tension screw on the extruder which worked for a while, but only a few minutes before it stopped again. I’m looking to replace the extruder with a Bontech type extruder. Anyone have any ideas on a suitable extruder for flexible filiments using a bowden tube or what i can do to fix the ones fitted to the A30M?

Hi, Flexible Consumables for Printing on Proximal Extruder.

Hi, are you saying I need a Proximal extruder on my A30M to print with flexible filiments?

Hi, If using flexible supplies,
This is best done using a short-range extruder.

[Deadeye]

Oh ok. So as the A30M uses a Bowden tube and remote extruder from the hot end, it’s really not suitable for printing flexible filiments
That’s disappointing

Suitable, but with very low volumetric speed. And possible you need to lubricate filament (use drop of gun oil to filament filter).
