I received my first batch of Taulman Bridge, added a glass plate to my Printrbot Plus V2 platform, used 50/50 PVA glue/water paste on the glass, heated the bed to 70 degrees Celsius and the extruder to 240. Worked great for a couple of small prints but each time I print something a little larger the nylon filament bends between the drive wheel and the hot end as shown. I don’t see this as a fault of the filament as that is the is the nature of nylon. I was planning to laser cut some new pieces that guide the filimant to remove the air gap between the the drive wheel and hotend but thought I would as the group for some advice first 8D Suggestions?
I’ve seen a few people mention installing a straw between the bolt and the extruder?
Also, have you calibrated the steps for the Extruder motor? I found my V2 was out for the filament I was using.
@Daniel_Porter Great idea. Simple and easy… I will definitely try this 
thanks
Let us know how you go!
The other possibility which I’ve read, and I know this happens on mine, is that the extruder stepper gets very hot and being that it’s a metal assembly, it heats up. So you could also try installing either a heatsink/fan on that stepper or installing an additional fan to blow cool air on to the bolt so the filament doesn’t warm up.
I agree completely and have already done this several months ago to resolve a PLA jamming issue I encountered when I built a passively heated enclosure for my printer.
I regularly touch the stepper to see if it is getting hot but in this scenario it was barely warm.
Try to reduce the pressure the guide wheel puts on the filament. If the guide wheel deforms the filament it will require more force to push it through the hot end sometimes causing a jam.
I added a “straw” that seems to have done the trick. Thanks all
Ptfe tubing is the best way to do it.
@Stephanie_A knows what she’s talking about. a PTFE guide tube is the best solution.
