What Exactly is an EPS?

Cobra Steve, Leather Machine Co., explains what an EPS (Electronic Positioning System) is, and how it can help you do a better job sewing leather. Be sure to watch the video too!

The EPS works by means of the electronic synchronizer which senses the position of the hand wheel as it rotates around its 360 degree cycle. There are two key points in this cycle. The first key point is when the needle has penetrated through the fabric and has come back up just enough for the machine’s hook to catch the loop formed by the thread. The second key point is when the needle and the take-up lever are at their highest points, which is when the stitch cycle is complete. The timing of these two stopping points is set at the factory by an expert mechanic. When you remove your foot from the actuating foot pedal, the sensor on the end of the upper main shaft can tell where the machine’s needle is in the stitch cycle. The needle position motor then advances and stops the machine at the next “needle down” position. The second stopping point, or the “needle up” position, is when the stitch cycle is complete so that you may remove your work from under the presser foot. To get the machine in this position, just push your heel down on the front of the pedal.

Perhaps this would be a place to put info on how to install this system. I got one on my cobra 4, and the basic plug and play instalation is pretty obvious, but it isn`t working as on the video. Probably something simple, maybe a programing thing on the motor. to recognize the eps is there. Great machine so far.

There are different types of Servo motor so keep in mind that these instructions only apply to one brand.

If anyone is still monitoring this thread: the link in the OP is broken.

Any way to add one of these to my Adler?

Depends on what accessories (screws + adapters) come with the motor but usually it is possible. Which Adler machine do you have?

I have a 467 from Nick-o-Sew

The top shaft should have a internal thread so it depends if the servo motor comes with the right screw or not. Usually they come with 2 different threaded screws.
