===== MJB-3s Are up=====
=====Suss SB6-8E=====
We found a blown resistor (and a questionable op amp) on one of the boards that contains the z-axis motor circuit. However, we still cannot get the tool to initialize. Next we will try swapping out the hard drive again and run some more tests.
The servicing is completed for both of the MJB-3s. The stage issue with the IR system has been resolved as well.


I will send out an update once we have one.

The tool remains down. We did not find any "smoking gun" with the PC but did find that the PC's power supply had a non functional fan and the power supply did not test as good (granted it would still power up the PC). We will continue troubleshooting the PC issue in the morning.
