Been working today on tidying up probing and tool change macros which is proving quite difficult.
I'm currently on 3.5.4
Biggest issue I am having is with occasional 'Tool is in use or Axis is in use messages' - the biggest problem with these are that they don't stop execution so a) It can cause head clashes and b) They are quick tricky to track down.
I got a surprising tool temperature requirement - absolute zero - which I need to try and track down the cause.
UPDATE: Solved this issue - I had missed out the S on my M568 - so just had 0 - handy to know for the future.
Also I am getting some quite strange behaviour with the U and Z axis - where sometimes when I do a Z move down it seems to also move U left (probably to where X currently is).
If I then move Z up again and U right - it goes a lot further than I am asking - presumably back to its proper position.
It's interesting seeing the head move in 45 degrees - but it is messing up my probing.
See <<< on line 74 in here for the place where it does the strange move.
Update - Solved - I removed all T0 and T1 commands from alignment/homing/cleaning sequences and that seems to have stopped the odd behaviour.
It left the possibility of parts of the macro's being multi threaded by replacing all T0,T1's with M596.1 T0/T1 - which will still do the tool switches when needed.

I have written a little wrapper macro form M596 - M596.1 - which a) Has the ability for M596's to be switched off, and be allows the tool to be specified instead of the motion system.
NB/ At present my tools and motion systems are swapped round - i.e. T0 is in motion system 1, and T1 in ms 0 - This was due to issues I was having when I have a servo on T1 (UV axis) - so I may well swap them back around at some point.
