Members KYCat Posted 5 hours ago Members Report Posted 5 hours ago I have a fairly new (2years) CB3500 that hasn't gotten a lot of use recently due to health issues. I've finally felt like doing a couple of projects and when I was going through the maintenance points I simply turned the power on and the machine takes off. The foot petal is 'up' and the arm in the motor is 'up' where there should be no stitching. There's a grinding noise coming from the motor when I turn the handwheel so it's not in the head unit. Any ideas on what caused this and how to fix? Thanks!!! Quote
Members Constabulary Posted 4 hours ago Members Report Posted 4 hours ago (edited) Guessing - most likely a motor problem. I guess the machine has a servo motor so I would guess the lever of the accelerator unit or the hall sensor is loose / has moved and is probably stuck in the "run" position. Please post some pictures of your motor and the accelerator unit and lever where the it man rod is attached and maybe a video showing the issue (please not just 5 second video or so" upload it to YT and post a link here.
