Upgraded to 4.2.7 board/ Homing Failed



  • I have an Ender 5 pro, I upgraded the mainboard to 4.2.7 and installed a BLtouch (V3).
    I flash the printer with "Ender-5 Pro- Marlin2.0.1 - V1.1.1 - BLTouch - TMC2235" from the creality website. But I've been having 2 issues,

    The first issue is that when I would use auto home, the motors would make a jarring noise. I think it's the nozzle trying to go past the xyx limit but I'm not sure.

    The 2nd issue is that eventually during the auto home or bed leveling it would send me this message "homing failed printer halted please reset". Not sure how to resolved it.
