Fagor alarm 3712: Home switch of the master axis is pressed when homing the slave axis
CNC 8060/8065/8070 servo/feedback error · Fagor 8060/8065/8070
What it means
During a gantry-axis home search the CNC detected the master's home switch before the slave's. Correct gantry homing requires the slave axis to hit its switch first so both halves square up consistently; this order violation aborts the squaring sequence.
Likely causes
- home-switch positions not adjusted after gantry geometry change or crash repair
- switch bracket moved or damaged on one gantry side
- wiring crossed between master and slave home inputs
