    Bed Leveling but with no Z axis movement

    Hi

    I was happily printing was my A8 since Xmas then (foolishly) I decide to upgrade to a BL Touch and every since I've had problem after problem, the latest issue I've been struggling with for the last week or two is that I'm correctly creating a mesh (i think) but when I try to print I would have expected the Z axis to move very slightly as its laying down each layer but no movement is seen and the print is never level across the bed. Below is a list on things I've checked or setup:
    • Z offset is correctly set at home position (middle of bed)
    • Bed Leveling is switch on on the printer display
    • I've installed Octoprint via Pi 3 but still dosent work via PC
    • I've tried different startup GCODEs and the latest is
