PicoMite (UKTailwind)FirmwareConfidence: Medium

After a hardware E-STOP trip, the next STEPPER command prints the trip report and then does nothing with no error raised, so the program carries on as if it worked; a STEPPER CLOSE right after a trip is dropped the same way, pins stay reserved, and the next INIT fails.
