I’m trying to run calibration on the print heads for my ultimaker s5 with material station. The material for extruder 2 feeds fine until it reaches the decoupler. I can see the material run through the lower Bowden tube until it reaches some point within the decoupler and then it hits something and the machine immediately throws out an error. I have no idea what’s going on here. I’m fairly certain the Bowden tubes are all attached properly, and the whole contraption doesn’t look different from the perfectly functioning decoupler for extruder 1. the material can retract from this point fine so it’s not getting stuck. It just seems to push out this little bit that clamps onto the Bowden tube all the way and then hits something solid and can’t go any farther.
