Extrudr TPU difficult to print


#1

This is the link to the TPU https://www.extrudr.com/en/products/catalogue/flex-semisoft-schwarz_2365/

The first try was by mistake with standard external ABS settings .
The print was impossible to separate from raft.

Then after looking to some suggestions on Youtube about TPU printing I try to lower the temperature but was unable to avoid filament retraction or control speed .
What is 100% speed for a M200 ?
Cm / seconds would be a more useful parameter.
