Hello @EddyMI3D
Hi, thank you so much for the tip! You were absolutely right. The homing brackets on the gantry were indeed installed backwards. Because the sensor couldn’t ‘see’ the metal, it never triggered, which caused the nozzle to crash and subsequently led to the ‘Lost communication with MCU’ error due to the impact/emergency stop. I flipped the brackets, and now it homes perfectly. Thanks again for your help!"
