I have an Ender 3 with a V4.2.2 PCB which has failed, So I purchased a new V4.2.7 all seems ok until I go to the home location where it moves to the centre of the bed.
When printing, the bed and hot nozzle get to temperature the head moves to the centre of the bed and stops, then turns the heating off. Also noticed the in the printing cycle the head does not move in the Z axis.
Any ideas how I can get back up and running.
