ScrapMonkey Report post Posted April 29, 2020 I own Juki 1508s . GOLDSTAR GSM550 will not let me go lower than 1600 RPM. I have speed reducer installed. This model uses a needle positioner that I like. Question- need a new motor that allows RPM 500- 3500 but also has needle positioner that fits Juki AMCO shaft. ( see picture of needle positioner) Or how do I tell the servo to go slower from computer module...Any opinions? Quote Share this post Link to post Share on other sites
