Flexible Filament Jams

[legoboy75]

I have been trying to print with flexible filament, but I cannot figure it out. I had done one calibration cube, and it worked, but after that it quit working. I have found the problem in the extruder with the attached picture. It always prints a little at the start of the print, but stops.

What kind of printer? Most printers cant print flexible filament stock. The filament path needs to be constrained. For my lulzbots I have a specially designed print head I put on when printing flexible

I have a Robo 3D R1. I figured out the problem. The extruder had to be raised higher than with a typical filament. I also raised the print temperature to 220° C.

slowing down the print speed will also help.
