i've purchased and assmebled a generic 3018 chinese CNC

i've added limit switches, and changed the settings, hard limits are on, and all switches work without any issue

the problem is homing, when i try homing, z axis goes up and the switch doesn't make it stop and just keeps spinning

Thanks in advance for any help

If you are using latest firmware, i had issues with woodpecker board, to use homing i bought an MKS DLC. some pins on arduino clones were repurposed in later grbl versions....
