Question About Enduro Servo Motor With Needle Positioning System

[Cobra Steve]

Are there any other functions on your control panel, like thread trimmer, or automatic foot lift? Steve

No, this is a very basic motor with just on / off switch and a switch for rotation direction. No control panel at all.

Well, this motor has to go anyway. I just wanted to be sure that other servo motors like the Enduros do not have this issue.

Wow. I'm thinking you have a bad synchronizer. If your synchronizer has the slots in the wheels for adjusting the needles down position, make the opening a little wider so the sensor knows it's time to stop.

I opened the sensor and figured it uses magnet for the positioning signal.

Thought I don't keep the motor, I will try to set the disc with the magnets closer to the sensors. If I ruin the sensor I have one spare so its worth the try.

Some pics.

Ah. The magnetic sensors. Vibration kills magnetism over time. Take a small rare earth magnet and place on each magnet for a period of time. Say 30 minutes. I have re-energized magnets in synchronizers this way in the past. Give it a try.

Holy Cow - thats a good idea.

I will try some neodym magnets. I think I have some floatings around here. Bringing the disc closer to the sensor did not work.

I just purchased a sew-quite 5000 nps and was having similar problem, extra stitch, and refused to stop at the top.

Reliable took it back, I had it returned no charge 3 days and works perfect on any weight material.

Maybe you just have a bad unit?

[Constabulary]

Eric, "reconditioning" the magnets did not work. I even tried to leave the neodym magnets in the sensor - no change at all.

[Tom Spivak]

Once again, if you are within the warranty period I would contact the place you purchased the motor from and have them check it out.

Even if you are not in warranty, why not call them and get their advice?

Good Luck.

If you've tried 2 different synchronizers, it's got to be the stop function on the motor or the control box. I do know on the Varistop units, a poor electrical connection or plug socket issue will do this. On my Juki 5410's, oil migrates from the sump pans, down the foot lift rod, right on top of the control boxes. I've started using silicone to seal the cover plates for the electrical connections. Oh, and you get what you pay for with these units. Just saying.

Hi Constablery, I would demand my money back for such dangerous motor. Its a very easy to stitch true your fingers. Its clearly a construction fault, it's not doing what it's supposed to do.

Good luck
