Reply to "Design Spot 250 09Er Error Code: Prism-Wheel Error"

Gines,
After we talked on the phone, I checked the connectivity between the prism magnetic sensor and the connector on the PCB. All 3 wires checked out good.

Also, I tried swapping the PCB with the good light, and it still gave me the 09Er code. So, I'm inclined to think that it's not the PCB. Or, do you think it could still be the PCB somehow?

I felt the resistance of the good stepping motor vs. the bad stepping motor, like you suggested, and they felt about the same.

So, I've eliminated the magnetic sensor. I've eliminated the wiring from the magnetic sensor to the PCB. I think I've eliminated the PCB (but maybe not). I'm not sure if I've eliminated the stepping motor. Not sure what else to try.

I will call on Wednesday to discuss.

Thanks,
Brian
