Acquired a Shizuoka B3-V mill and I can’t home the Z axis. I keep getting an over travel +Z alarm. I cleaned the limit switch and even dismounted the switch but I keep getting the alarm. Did notice the machine had 2 lines that I assume need to line up for the tool changer to work ( and the home position) but the alarm activates before they are inline. Assume that’s almost like a Z home reference too. The Z axis wasn’t supported during transit. Could something have gotten misaligned during transit or do I have a bad limit/ home switch? TIA
