Bowden tube pops off pneumatic fitting
I'm having trouble making prints because the Bowden tube won't stay connected to the pneumatic fitting on the top of the filament drive. When printing starts, the filament pushes up the Bowden tube which then causes filament to stop exiting the extruder. I was able to print a "Bowden lock" by holding the tube down by hand during printing, but the lock itself doesn't work. The filament still pushes the tube out of the fitting even when the top of the fitting is raised. It doesn't seem to have enough grip on the tube. Does anyone know how I can get the tube to stay connected?
Is this a good question?
