See if that works it doesn't always turn that far sometime it stops instantly as you turn the main shaft it feels like its under pressure till it goes thew its cutting step

on the back in front of the timing wheel there is a plate with 4 screws, take that off and see if something is binding in there. You may need to oil or grease it.

belts and gears all look good from timing wheel down made sure mes cam and everything was greased well still happening if I run wiper test and cam test they all work great only on a trim function it does this the machine sews great

take off the cover on the top of the sewing arm and see if anything is binding there. If that isn't it then look at the hook, hook timing, needle bars.

Does it happen on every needle?
