I find that the EPS function comes in extremely useful when doing tight curves as in wallets when they are stitched all the way around gussets in handbags and such for the reason that as the curve gets tight it is necessary to take the foot pressure off and let the top relax. If you were hand stitching you would need to have the holes inside the curve closer together than the outside curve of the article. When I stitch the bottom of the gusset in these clutch bags I lift the foot maybe 15 or so times and the needle stays in to keep every thing straight. The leather that has the pressure taken off then allows the needle on the next step to go slightly further on top. With out this happening the bag would deform quite badly and end up twisted. You can do this with a knee lift or foot pedal but the time and attention would make it way slower.

This pic shows some of my typical clutch bags with a fairly tight gusset area.

This wallet shows how I prefer to stitch all the way around if possible and that requires 2 or 3 foot lifts in the tight area and is handy for the corner turning as well.

A bag like this one requires many foot lifts in many places and although quite thick and hard did not need any speed reducer.

I can only add that if you can take a bit of firm/hard leather and try out one with an EPS it should help make a decision that suits you best.

I have an EPS on all but two of my machines. One also has both an EPS and a speed reducer. The control I get with the auto positioning of the needle makes my work much easier. The slow precise stitching I do pretty much demands it. As an aside, the EPS and speed reducer get along fine on my machine.

As mentioned above, I as well have both speed reducer and EPS on my Techsew 5100 and they get along fine.

Seems it depends on the installed motor if SR and EPS (or NPS) can work together. I remember a post here where a member from Germany added a 2nd magnet to the EPS sensor and solved the issue but I´m not sure if this works on all servo motors - I doubt this. I´m one of those who do not need at EPS (yet - but you never know).

dfrensdorff..I seem to remember before ( a year or more ago ) someone saying that Servo+speed reducer+EPS worked well on Techsew..was that you ?
Is that all set up at purchase ? Not that I'm in the market, but might well help for others to know..

What is your machine that has it Joe ? a Techsew..or something else ?

Yes this is something we set up at the time of the order. No issues here with speed reducer + EPS combo.

There are lots of EPS motors out there, some might not have the appropriate programming to allow for use with a speed reducer.

I should add that my NPS is mounted on the 170mm pulley that replaced the original handwheel on my Durkopp 239. Had to make a bracket to fit it.

It wasn’t me ..... but like I said mine works well together, and I love the needle positioning portion of the drill!

Maybe we should compile a list of servo motors that work with speed reducers of certain reduction ratios.

Could be helpful when looking for a specific servo motor
