When the trim card for MQB1A02 (channel 18) was swapped, many magnets within the rack mismatched (Figure 1). After the swap, the magnet was still having issues, so the card was swapped a second time (Figure 2). Although there were significantly fewer, some magnets mismatched again. Both times all magnets were able to take setpoint and cycle.

Tried to optimize the injector and get high current. Got 90uA to FC2 but the transmission is low. The work is not done yet. Backed out the changes so that Ops can tune the main machine. Will continue the work when time is available.
Fig. 1--- 90uA to CF2 but the transmission is very low.
