Hi all,
So I have issued now M303 T0 S220....
Everything goes ok-ish; and after 24 minutes of 'tuning', I got:
Warning: heater behaviour was not consistent during tuning
Auto tune starting phase 4, measuring with fan on
This happens to both my hotend and my bed. Bed is AC powered by a relay.
Any help/advice?

@Phaedrux Oh brother, rookie mistake. Broken wire. Tested continuity and then realized it was broken - I'm such an idiot!
A bit of a different Q, but still on this (kinda); what AWG wire do you use for the end stops? (And for the rest of the electronics?)
@droftarts Hi!
Thank you very much! 
Sometimes I just need to explore a bit more hahaah
Wishing you an awesome day,
Tinus
@Phaedrux Cool thank you Will have a look at it - I suspect the wire I was/am using is too thin - where I crimp it, sometimes it brakes off - and that means looking for trouble. The other wire I have is too thick - wonderful living in Africa!
PLEASE mark this also as Solved?
Eureka!

Manual corrections required: 0.00 turn up (0.00mm) 0.00 turn down (0.00mm) 0.76 turn up (-0.38mm) 0.81 turn up (-0.41mm)
The M671 I used to define the springs positions was not correct.
Hi,
Sometimes due to mechanical reasons (and the wonderful accuracy of my build) I experience that some of the 3 Z axis goes out of 'alignment' - so it inadvertently tilts the bed. Is there perhaps a G-code that I can issue to let me move one of the Z stepper motors? I will make maintenance (greasing and cleaning the lead screws) a lot easier too!
Any/all help appreciated!

@jay_s_uk Thank you! Got it working 100% Can you perhaps mark this post as SOLVED?
@phaedrux Hi. Yeah tested with a sock too. Same result. Hot end fan is isolated from heat block - there is like a round 'O' of plastic (like a divider) between the heat block and the fins.
Also what is the approximate time of a PID cycle with defaults? I quite frequently have 30+ minutes. I even swapped out the board this morning. Same result!
My layer 1 printed perfectly. Just after beginning on layer two, temperature exceeded by 15 degrees; and cause a heater fault.
Also:
M307 H1 R2.0 K0.545:0.322 D10.96 E1.35 S0.80 B0 V24.1 ;V3.4RC1
M307 H1 B0 R2.788 C90.8:60.3 D10.93 S0.80 V24.1 ;V3.3
@owend I will try a different firmware version tomorrow, however 3.4 is needed to keep my mini12864 up and running. My overshoot is typically 10 to 15 degrees at the moment...
@phaedrux Everything is firmly secured - did double check it
The only thing that may be a little weird is the gap between the nozzle and the heat block, may be a tad big.... but that should not be an issue, should it?
@phaedrux That's the 'D' parameter in the line? To what do you suggest should I decrease it?
Sorry I have not uploaded a photo yet - been a bit busy- only got the printer fully assembled again this evening - weird thing now is the temperature stays about 10 to 15 degrees HOTTER than requested.
Did a tuning with 200C and PWM of 0.8 and this was the result:
M307 H1 R2.723 K0.545:0.322 D10.96 E1.35 S0.80 B0 V24.1
