SM2 problems loading very flexible (60A) filament?

Does SM2 have problems loading filament, which is too flexible?
I’m not talking about problems in the printing phase where some guys came up with printed adaptors.
I’m talking about SM2 being unable to load very flexible (i.e. 60A) filaments.

Yes, it is the same issue seen during printing; the extruder access door spring tension against the filament/extruder gear.

Thanks for the reply!
Does it work with less flexible TPU?

According to the shop page, the Dual extruder needs 90A or above. I cannot immediately find it, but there’s a thread in this forum where someone mentioned getting in contact with support on that, and I seem to remember that they added this information on the shop page after that.

For the single extruder the page states 95A:

Thank you very much! Your information is much appreciated! :star_struck:

I don’t know the hardness of the TPU I was using… but I found if I could keep tension on the filament, it would print. Albeit, much slower than the other hard types.

Clamping pressure of the single extruder of SM2 is too high, so you can reduce the clamping pressure by sandwiching the paper in this way.

And, this supplementary part is also very useful.

I use this adapter which made with a 0.1mm nozzle attached SM2. That’s great.
