Janome Memory Craft 8000 Stepping Motor Error
Bear with me here...
When the Janome 8000 is turned on, one of the first things that it does is run the stepper motors to return the embroidery carriage back to its original position.
The computer in the Janome needs to know when the embroidery carriage is back in the correct position and to do so, it uses a sensor.
If the sensor fails, it does not know that the carriage is back in the correct position.
When the sensor fails, what happens is that the stepper motor keeps running even though the embroidery carriage is fully back, so what you hear is a horrible grinding sound. The grinding sound itself is nothing to worry about, actually it is good news, it means that the stepper motor is fine.
Janome in their infinite wisdom decided that whether the motor failed or the sensor failed, that they would simply say on the screen that the stepper motor failed.
I have repaired a machine with this problem, in my case it turned out that the sensor was okay, but someone had damaged the main circuit board, breaking the track from the sensor to the computer.
Unfortunately, I don't know if this sort of repair is something that the average repairman can take care of. I am an electronics engineer, so thats why it wasn't a problem for me.
I just thought some extra information on what is going on might give you a head start in getting some one to fix it for you.
