Feeders hitting and breaking needles?

    Hi Lula, could you share a few pictures of your feeders close to the needle bed to see their exact position? Could you also share a picture of the top part of the feeder, the part attached to the rail? Sometimes, when needles hit the feeders, they get misaligned and can't work properly until they are adjusted again. Thanks!

    Thanks Gerard-Rubio, I'm hoping it's something as simple as that and that maybe I'm just failing to get them realigned correctly.

    I took a bunch of pictures of the current feeder alignment:

    Oops, some of the pictures failed to upload the first time.

    Thank you for all those pictures Lula. The tip of the feeders look ok. I would adjust feeder one a bit, though, to be more like this, in red below. A bit more towards the rear bed.

    Are your brushes in good shape? Could you move the carriage to the position where you placed the feeders for the pictures, and take a similar image of them? Thanks!

    Hi Gerard-Rubio. I had to step away from the knitting machine for a while for irl reasons, so I'm only just now getting back to it and I've figured out what the issue is, but not how to fix it. 

    It seems like the issue is with the carriage and the yarn carriers. The tabs beneath the carriage (I don't know what they're called) that are used to pick up the yarn carriers and guide them back and forth on the rails are causing a delay for two of the six yarn carriers. For whatever reason the tabs are catching for a second on the back slope of the yarn carriers before settling into that middle section, causing the carriage to push the yarn carrier ahead of where it's supposed to be, which is causing it to collide with a break needles. I was having so much trouble finding the issue because it only happens to some of the carriers (3 and 4), only sometimes, and only when the yarn carrier is close enough to the piece that it will collide with raising needles.

    Here's a video of what I'm talking about:  Sometimes it seems to push the carrier for much further than in the video, maybe based on speed? I'm not sure.

    I'm hoping you know what I can do to solve this issue :(

    Hi Lula, Thank you for sharing the video—the issue is clear now. Can you check if your feeder is too tightly or loosely attached to the rail? 

    I made this video to show you how tight the feeders must be attached. They have to have just a tiny bit of play, as little as possible, without clamping the feeder on the rail. Once adequately oiled, it has to move smoothly in both directions.

    If you follow these instructions and it continues to happen, I would slowly increase tightness. There should be a point where friction between the feeder and the rail is greater than the one between the selector and the tab; then, the selector should slide up and fall within the tabs. Please let me know how it goes. Thanks!
