BSmithy Report post Posted December 27, 2019 So I just got my brand new Cobra class 4 yesterday from Leather Machine Co. With help from the instructions and the video I got it setup and on its table and everything. Plugged it in and all was fine and dandy, until I tried to sew. Worked for about maybe 3 seconds and then the motor started flashing a E5 error code. Consulted the little piece of paper about the motor and it says its the Synchronizer is fault and to check it and the position signal. I haven't the faintest clue where this synchronizer is or looks like or anything. In no piece of literature that I have access to is a synchronizer mentioned, the DVD doesn't mention it, no YouTube videos or anything. Please help, the leather machine co people are out of office till the 2nd of January so I can't call for help. Let me know if I need to include more information about the motor. There isn't much.

I would call them, and I tried, but they are all off on vacation till the 2nd. But thanks anyway, this might give me some more information to help narrow down the search for answers.

dikman Report post Posted December 27, 2019 I assume you actually bought it with a synchronizer fitted? Sounds to me like the problem you get when there's no synchronizer fitted but it's turned on in the control box. You should have a "manual" for the motor to explain what the codes are and how to access/change them and turn the synchronizer function of. Quote Share this post Link to post Share on other sites

You should have a "manual" for the motor to explain what the codes are and how to access/change them and turn the synchronizer function of. The manual for the motor is one single piece of paper. I have looked through the other manual for the machine itself and there is no mention of a synchronizer or anything like that. I honestly don't even know what this thing would do.

dikman Report post Posted December 27, 2019 Ok, looking at the website the Cobra's don't normally come with a synchronizer so I'd say you don't have one (it sticks out from the end of the flywheel). Can you tell us what brand the motor is? Can you post a photo of the "piece of paper"? A photo of the motor and front of the control box? If we can work out what the motor is - brand, type etc - it shouldn't be hard to find the instructions. On one of mine the codes etc were stuck on the side of the control box.

BSmithy Report post Posted December 28, 2019 I appreciate all help on this, I finally figured it out. Through an insane amount of button pushing on the annoying little motor panel. I found a setting that I didn't know it had, nor did the instructions mention it, or any video ever. And that seemed to be causing all the problems. Now its sewing like a charm (once I got the threading part down). Quote Share this post Link to post Share on other sites
dikman Report post Posted December 28, 2019 Excellent! I'll bet that the EPS (synchronizer) setting had been set to ON and you've managed to turn it OFF. If I were you I'd still chase them up when they're open and ask for a copy of the motor settings. Happy sewing. Quote Share this post Link to post Share on other sites
