Printing Flex: TPE32
Hi,
I went for the adventure of printing flexible filament. I have TPE32 from Filament PM, which is on the harder side of the scale.
What parameters do you suggest to tune?
I use 0.4 nonHF nozzle, I reduced tension of the idler. In slicer, I started from the profile publish by the same company for softer filament. Reduced volumetric flow to 2mm^3/s. I print on PP tape, no bed heating.
At one point of the print I got sticker filament warning. I attempted to reload the filament, but unload failed. I found the filament folded between the extruder gear and housing. I had to disassemble the head.
Since the filament location, I attributed the problem to retraction. Set it to zero, tried again.
This time the print completed, meaning it reached 100% counter. However, the extrusion stopped at the same point of the model, probably with slipping extruder gear. When I was unloading, I pulled on the filament, but probably too little, as it got jammed in the same exact location. I had no problem to pull the filament from the nozzle and put of the filament sensor, but to clear the jam, I'll need to disassemble again.
So, any ideas what to tune next?
