Problems to print with Semiflex (Ninjaflex) - HELP!

[levor]

Hello everyone!

I have problems to print items with semi flex. Usually it stopped printing when the item is already 80 or 90 percent done and only once, it worked completely.

I have a Mendel Max 3 printer,
2015-12-09 21.22.36.jpg
have that material: http://www.amazon.com/dp/B00TBQMN86/ref=biss_dp_t_asn - Ninjaflex 3DSF001175 SemiFlex 3D Printing Filament, 0.50 kg Spool, 1.75 mm Diameter, Snow

and used that setting

Maybe someone has more knowledge about dealing with that kind of material. I really need help about that, any advice could be helpful in order to get finally successful prints, always and not only sometimes. Like I said in the beginning, after a while it just stops printing, no materials comes anymore. Maybe I have to change sth. about the speed?

Best

Levor!

What was the Actual nozzle Temp ?
I've read that 220 C is best for Ninjaflex,
but I've not tried it yet .

You may need to monitor the nozzle temp with an external digital thermometer,
with thermocouple-probe,
if the printer's indicated temp is not correct.

We have found regular ninjaflex easier to print with than semiflex. Ninjaflex uses the same gcode settings as ABS, but higher prime/unprime values on the heads.
