All this chaos was the bobbin case bent and hitting the feed dog teeth The connecting rods stopped jumping around and it sews like a dream.

I chased my butt on my 255 randomly cutting, fraying 138 thread, switched to a 23 and it never happened again. I sewed a boat cover with over 400 feet of stitching and the thread never gave me problems.

Here's a video of the connecting rods moving around. Sorry for the poor video quality.....

Yep, you read that right! My friends gave me their juki since they are moving away, brand new table, and a new Rex servo motor. The wife bought the machine 6 months ago, the guy never offered to sew with it, she just showed up, paid him, and left. The guy was considerate enough to load it for her, but, the numpty didn't take the head off the table. So as she pulled away it dropped out of the hole and fell down. That's the picture she sent me after it fell. It broke the tensioner, she replaced it. I turn the wheel and there's a bad stiff spot, I believe it's coming from inside the hand wheel area. I removed the cover on the top and I noticed the connecting rod bars move left to right along with the center drive shaft as the stiff spot shows up. I'm curious if the shaft is bent at the wheel, or if it bent at the front where the arms stick out. Anyone have an idea where to start with this? I might be able to put a dial indicator on the rear of the machine and see if the shaft walks. I'm not a juki guy so IDK to be brutally honest

Hello everyone, long time lurker. Middle of last year, I bought a Consew 225 for cheap. Built a table for the machine. Learned on it. Built a custom motor for it. Then bought a Consew servo motor and fabricated a homemade ball bearing speed reducer. Bought a virtually like new Consew 255rb for cheap, sold my other machine. And I've been using it nightly. I'm redoing the upholstery on my boat. My OCD works in my favor when it comes to my craftsmanship. I'm really happy how the few pieces I've done turned out. Being a fabricator all my life certainly helps too. My question starts here. The machine developed a strange back stitch issue. Along with the hook assembly sounding ( rough) I found the needle bar was 2.5 mm higher then it should have been, ( I blame the needle I broke during one of my upholstery pieces) but the issue finally went away today when I adjusted the bobbin tension to be very little. My stitches are very nice, and my back stich stopped having the little loops when I'd hit the lever. The bobbin would spin about 1/3 to 1/2 a turn, and for a 5/6 stitches I'd lose top thread tension. I chased it for the last 2 weeks, tinkering here and there. So anyway, that's my story. I've had more fixing jobs then creating. Just having fun while learning.
