I thought I would jump on this one, the extruder on mine also seems to be skipping, the prints look fine to me so far. I have tried to push the PLA into the extruder gently, but that seems to do nothing. Since it isn’t affecting my prints I will leave it for now, I have bought an MKS gen L which I’ll install once I have got a good idea of how the included board works. If the clicking persists after the new board, I will continue troubleshooting.
