- Acquired an old Hermle UWF 851 CNC mill with Fanuc 0M controller, facing challenges due to lack of experience with industrial machinery.
- Spent months getting the machine operational, including upgrading workshop electrical supply to 63A from an insufficient 16A three-phase.
- Encountered persistent alarms (e.g., 1002, 400, 414) related to spindle, servo overloads, and axis detection errors, partially resolved via troubleshooting.
- Achieved basic functionality: writing and running programs via MDI panel, but serial port for loading CAM programs initially failed despite various adapter attempts.
- Finally succeeded in receiving programs using specific RS232 adapters, though data sending remains problematic due to DR signal issues (P/S Alarm 086).
