Auto Bed Levelling Glitches

[Roxy]

When I built my printer, I had some problems with it doing crazy things... I spent a lot of time understanding how the firmware worked so I could add debug code to it. I don't understand all parts of it. But I do understand most of the stuff I have enabled. One thing about this firmware is there is no operating system sitting under you to provide support. What ever it needs, it provides. So, that does complicate things from one perspective. But from another view point, everything is there and only stuff it needs is in the code. So from that stand point it simplifies things.

The Marlin firmware is really just one big loop that reads in GCode commands and processes them one by one. So, from that stand point, it is pretty simple.
