Members nautilu007 Posted January 30, 2019 Members Report Posted January 30, 2019 Hello, I bought my Cobra Class 26 3 week ago (NEW). It´s really nice machine, and I like it a lot. But I have problems with servo motor and controlling the sewing speed. When i set speed on for example 15. I cannot sew slowly. When I press foot pedal, just a little bit it, sews immediately fast. And when i set speed on 5, it sews slow, but sometime accelerates for few stitches (like on number 10), and than slow again. But my foot pedal is still. Maybe you have some suggestions what can i do? I tried a lot, but probably not everything. Thanks a lot and have a nice day Quote
Members Constabulary Posted January 31, 2019 Members Report Posted January 31, 2019 (edited) I would assume your V-belt and / or hand wheel is too tight. Just a guess w/o sitting in front of your machine. If you bought the machine from a dealer just check with the dealer. Where in Germany have you bought a Cobra 26?

Moderator Wizcrafts Posted January 31, 2019 Moderator Report Posted January 31, 2019 What make, model and voltage is your servo motor? A 600 wide x 400 high pixel photo of the motor would help.
