Don't suppose you know of a way to have it automatically set the head to Z=0? I'm having to do it manually most times as it seems to think 10mm above the bed is zero.

I have done what I've read though; which is to run G32 (The bed probe routine) quite a few times, then type M665 and M666 into the console and copy the results to my config.g file. What difference that all makes I don't really have any idea yet - lol.

It means that the calibration results are applied when you start up the printer. So even if you don'd run auto calibration before a print, the calibration should be reasonable accurate.

Perhaps you have the H parameter in the M665 command in config.g set about 10mm too small?
I suggest you set Z=0 manually, then run auto calibration. Check that the Z=0 point is still correct. Then run M665 with no parameters and copy the values it reports into the M665 command in config.g. Do the same for M666.

My M655 figures are pretty much identical (give or take 1mm or 0.5mm here and there) to those in the config.g. Same with M666.
Ah well. No big deal.

In that case, can you clarify what you mean when you say the printer thinks Z=0 is 10mm above the bed?

OK, try this:
1. Home the printer.
2. Send G1 X0 Y0 Z10 F5000. Is the nozzle 10mm above the bed?
3. Send G32 to auto calibrate.
4. Send G1 X0 Y0 Z10 F5000. Is the nozzle 10mm above the bed?
