[Solved] I just persevered with levelling the machine. I guess my issue was not so much "try, try again" as much as if I "try, try again" will it be in vain...

I know I did not get any replies, but for anyone in the same boat as me, my advice is to keep going and try and get "something to stick" and build on each little win at a time... I wish you luck as it can be very frustrating ....
