Its official. I hate this thing. Its SOOO unreliable. This time however it might have got damaged when some drilling took place on the frame of the printer. Looks like the bridge rectifier has blown! It can be fixed (my electrical friend tells me) but I hate this box anyway. Ok, it does an important job. It controls the motor which drives the camera on the Oxberry. This requires a stable 18volt DC supply for a duration controlled by the motor feedback. The motor is hugely expensive to replace but modern drivers do exist but they are very complicated to set up. Lots of people just run these machines with modern stepper motors. Also, when I was testing the motor to locate the fault I managed to fry the logic chip on the motor feedback board. Great! So currently no camera!!
