Today, the team fixed the issue we had yesterday. It was the result of installing a bigger carbon crucible without adjusting the limit switches. It caused the electrode holder to contact the crucible and short the ground. The limit switches were supposed to prevent such a thing to happen by signalling the microcontroller to stop the stepper motor that controls the electrode's height.
We tested the foundry in automatic mode with the bigger crucible and everything went perfectly. We casted a larger gingerbread man with about 700g of aluminum. Gingy now has a big brother. Stay tuned for the video!
