Uwe Report post Posted February 13, 2015 (edited) So I've been working on getting my newly acquired Adler 205-370 set up the way I like it. I'm not fond of clutch motors and got an Enduro Elite SM1050-2PF motor and refinished/modified the stand. The problem was the new motor design did not allow me using the existing pedal linkages and speed reducer. After some testing I decided to move the optical control unit from the motor box to a remote enclosure to avoid constructing some weird linkage with too many joints. On this motor there's a five-wire cable that connects the optical input to the control board. I made an extension by soldering an extension in the middle. I have surely voided any warranty! The end result turned out quite clean and functional and with very precise control due to direct actuation of the control lever via the pedal without any relay linkages. The trick was to get the pedal axis perfectly aligned with the axis of the optical control lever, so that they rotate in perfect unison. In any case, I thought I'd share my solution in the hopes that somebody else might find it useful. I'm attaching some pictures that hopefully tell the story better than my words. In case you're wondering, those nice wooden pedals started their life as Ikea cutting boards, mounted to the base via sturdy door hinges.

Gregg From Keystone Sewing Report post Posted February 13, 2015 Sweet, I was about halfway through doing this to a same type motor and then quit. It's really a great idea and execution. Efka for example on their AB321 motor motor controller uses an external motor control arm that is mountable in the same way. Again, this looks great, nice job!

Uwe Report post Posted February 13, 2015 (edited) Thanks for the kind words, Gregg! I'm not really familiar with Efka models, but I had come across some other servo motors that are designed with separate motor, controller box, and pedal actuator that connect via wires. The Goldstar GBSM 550s is one example. This is where I got the idea to separate the pieces, but I have no experience with that brand of motors.

Can't wait till tomorrow morning so i can go down stairs and see what i got and what i can do . I'ts good timing too .I am just about to order 6 new servo motors for a shoemaker friend of mine to upgrade his machines and if compatible i might use the UWE method .
