I don’t know. The synchronizers work fine with speed reducers. I have them on two machines. Since the speed reducer is ahead of the synchronizer mounted on the handwheel and it works off of position it doesn't even know if there is a speed reducer. Quote

From what I can tell, there are different ways to keep track of the needle position. One would be to only use a sensor that would keep a constant and absolute position of the needle, another way would be for the sensor to only to keep track of the needle every 360 or 180 degrees of rotation and compare that to where the motor position is. The position sensor that I purchased only provides a position pulse every 180 degrees. Just my thought on why some systems would work and some do not. Edited March 8, 2021 by jackalopes Quote

That’s great if most do work with reducers - I really don’t know - just repeating what a few people found and talked about in previous posts. I should stop throwing away synchronizers and actually try one, but I sew so slow that the needle just stops when the gas pedal is released. Lol Quote

I have two synchronizers and don't actually use either one anymore. Quote
