Members marinicarlo Posted March 23 Members Report Posted March 23 Hi there! finally I have got a wonderful setup: - Necchi 840 triple feed - servomotor with needle positioning system (Vevor 750 w) - LARGE CUSTOM (3d printed) pulley My servo low speed is 100 rpm with 45 mm pulley My custom pulley (mounted directly on the machine wheel) is 180 mm. so with low speed i can go as low as 30 stitches x minute with an incredible torque and control. Of course the servo allows me to go faster if needed. NOTE - Needle positioning and large pulley WORKS together! This is my pulley: see the low speed !!!! Quote
