/diy/ - Do It Yourself

So the next problem is the carriage. Sometimes it goes too far to the right or left. Since it only checks the left dead point via a micro switch and only on startup, it keeps hitting the left and right edge of the rail it's gliding on. The motor moving the carriage has more wires coming from it than motors usually have, so I suspect some form of rotary encoder in the motor housing.
Two possible scenarios:
1. The encoder or the wires coming from it are broken.
2. The logic board has a problem with reading the encoder, either because of a cold/broken solder joint or because the IC decoding it was fried when the caps on the logic board blew.
Since both the motor and the IC are nigh impossible to get, I really hope it's just a solder joint.

Also, picrel is my jury-rigged PSU.
