The old forum thread does not have the picture any more so I cannot interpret what is wrong. But it does not matter. I can give you few ideas.
There are 2 kinds of auto-leveling:
* the original grid based (this one does not fix calibration errors, it only fixes Z-height error while leaving X and Y errors there)
* Rich's auto-leveling [github.com] (this one actually fixes the calibration parameters and if you do not have too many errors there then there is a good chance it will converge; Rich provides some level of support on google deltabot group)
There are at least two ways how to calibrate the firmware manually:
* the old manual way (even in this case it may be useful to read the beginning of the calibration document mentioned in the next point)
* for math geeks only: there is a semi-manual way using this: [github.com]
* and of course there are tens of delta calibration how-to pages on the internet (some of them may be even correct :) )
