@jay_s_uk Yep you are very right, have just uploaded the later firmware 3.4.0 and it worked, many thanks for your help.

@jay_s_uk Yeah i am trialing the revo hotend with the upgraded smart efficator board (a lot more accurate and less prone to the vibration issues when bed levelling) and using a fixed mounted hemera extruder not the flying spring mounts, seems to be more stable and prints faster.
