Hi,
I had some successful prints with 70A TPU filament. I am using a 0.6mm Nozzle, max. volumetric flow at about 2mm^3/sek. The critical part of printing this soft material is loading it into the extruder! I don´t use any teflon tube and feed the spaghetti right into the extruder.
I use the “Load” function out of the P1S menu - the purge routine is way too fast and leads to extruder clogging. Is there any way to slow down the extruder for these menu operations? The max. volumetric flow parameter in the filament setting comes into play when printing only!
Thanks!
Manuel
