Members DrmCa Posted January 20, 2022 Members Report Posted January 20, 2022 If you know how to set it up, go for it! But for me personally I am exploring the option of using a lawnmower PMDC connected through a speed controller. PMDC allows to reverse the rotation to CCW that the Chinese patcher needs (most other motors are CW), and the controller allows to slow it down to a crawl by way of a tiny pulley. My patcher is on a portable base, so I cannot afford the weight of a full-blown servo motor, which you may very well consider.

I have a Rex 550 watt servo with this reverse rotation direction switch while my other servo's don't have that feature. kgg Quote Juki DNU - 1541S, Juki DU - 1181N, Singer 29K - 71(1949), Chinese Patcher (Tinkers Delight), Warlock TSC-441, Techsew 2750 Pro, Consew DCS-S4 Skiver
Members DrmCa Posted January 20, 2022 Members Report Posted January 20, 2022 (edited) True, but most of them are too heavy for a portable setup, in my particular case. Also, sewing machine servo motors are already CCW.
