Our space has an Ultimaker 2 that, up until a month ago, was working great until someone used 1.8mm ABS with it and on top of feeding issues the filament broke in the Bowden causing a serious jam. I was using 2.85mm Ultimaker filament on it with no problems. The Bowden was replaced (twice), but now I can't get anything to feed through it. I've tried the atomic cleaning method (https://ultimaker.com/en/community/5118-blocked-nozzle), and snaked a few strands of fine-gauge wire through the nozzle. Any other recommendations?

I was hoping I wouldn't have to take it all apart just yet, but I haven't looked at the PTFE coupler. It's a relatively new printer, so I don't think that's in bad shape.

    The PTFEs can sometimes get destroyed pretty quick with ABS.

    If atomic pulls are coming out clean and every thing else seems good then it's probably time to check the coupler.

    You should post a picture of the results of your atomic pull (the filament strands). That can usually give us enough info to determine if it's a PTFE problem.

    If it is the case that you do need to take it apart, I suggest getting a TFM coupler (the new UM2+ couplers) as they last a heck of a lot longer than the PTFE ones the UM2 came with. Also consider upgrading to n olsson block so you can change nozzles easy.

    If you don't have an olsson block or block v3 then I suggest that.

    It makes it so easy to just remove the nozzle and clean it out (or throw it away) (I usually put it in a flame - with ABS by now it's probably cooked to gum like conssitency but a toothpick can probably get it all out - or you can burn it all out).

    You could also upgrade to a stronger feeder that feeds with much more force that will give you a lot more headroom before you enters skipping and grinding issues.

    Our Bondtech Feeder is highly appreciated from many users.
