I started a print today and left. When I checked it for the first time after 15 minutes, the CR6 printed in the air.
I stopped printing and did home leveling, but the printer stopped too far from the heatbed. The Z-sensor is activated and the printer stops.
I haven't changed anything since the last successful print, possibly I turned the Z-axes to remove filament from the nozzle. But even if I turn the Z-axes again, nothing changes.
I have downgraded the firmware from the MB and upgraded it again, without success.
Can somebody help me?
