My homeing sequence fails during machine set up. It moves forward, but won’t stop. Just keeps hitting against the actuators.
Where are your switches located? Z up, Y away and X left?
Copy and paste your GRBL settings.
It sounds like your machine is either misconfigured or tripping false Z-limit switch because Z need to clear first before X/Y move during homing ($H)
Make sure the stop screws for each axis dont prevent the sliders hit the switches.
