Thank you Mates for the Information, i will not print hard Material with the Flexyhead.
Printing at higher Temps? What is the allowed printig tenmp with this Head?
I am asking because i have my free Day Yesterday and i was more printing and testing different flexible material.
After 3-4 Hours printing i change the Filament from Filamentworld Filaflex to Ninjaflex Fire red, Printing with 20mm/s.
First Print 30 Minutes was with 225 degrees and no Problem, 2nd Print 50 Minutes 220 degrees no Problem,
then i start to Print a Sampel (3Hours) but after 5 Minutes i hear a “klack klack” then normal sound then again Klack Klack.
I was by the side and stop the Print, tryed to reverse the NinjaFelx and the Ptfe Tube comes with out!! (see Attachment Pic.)
I have built the Printhead down and open the 13mm screw nut and the Motor screws, then i saw the Ninjaflex inside.
It was completly drilled and tattered. I clean the Filament from there and because the Ptfe Tube… i push them slowly back.
Then I put everything together and test the Printer.
But on every print at now i hade the same Problem.
I have clean the Filament a second time after them. Now i was again looking what happend and i found the Problem.
The Filament is so soft when the extruder pulley push them to the nozzle he drill them and push the NinjaFlex little bit outside
where the Extruder Pulley turns out!!! Then them Motor stucks and the Klack Klack beginns.
I have 2 Videos but i they have 63MB and 140 MB and i dont now where to upload
I try to slow the speed nothing happend better, after several time Dismantle and reassemble the Flexhead i try with Polyflex Filament.
But the same Problem beginns after short time there also.
So i think the Ptfe Tube is … little bit…worn out!?
Did is possible to order that as single Part? From Support?
