Jamming Issue with Bondtech N2 dual upgrade

Postby John W » Sun Apr 28, 2019 5:34 pm

Hello everyone!
I've had my N2 dual for almost 3 years now and I'm very satisfied, however, for the past week I've been having some troubles.
Some background:
I upgraded to Bondtech after my warranty expired just under a year ago and all of my hot ends are new V2s. Machine is also well maintained. Not using any new filament brands. Finally firmware is 1.1.6rev1

So last week I noted that I was getting an airprint, my first since upgrading to Bondtech (other than operator error) so I promptly unclogged the machine and tried again and got the imfamous clicking sound that usually accompanies a clogged nozzle. I switched hot ends to the right side which I never used to the left side and again got the clicking sound. At the recommendation of someone I bought some nylon cleaning filament and it went through without any issues, but as soon as I switched back to PLA (at the appropriate temperature) I got the jam again.
I thought the stepper motor might be bad on the Bondtech so I switched to the Right side to be sure and I was able to run nylon without issue but got a jamming noise as soon as I tried to preload PLA. I've run out of ideas for things to test and check. Any idea what could be causing this issue?

Thanks in advance!

How tightly are you setting the tension screws on the Bondtech? I have a similar system to you, except my printer is an N1. Try backing off the screw tension to 3-4 turns back from tight. Since I set mine like this I have not had any 'extruder clicking'. I don't print a lot of PLA though. Mostly I print TPU and PETG.
