Head crash when moving past 1mm
This is driving me nuts! So far in fact that I put Marlin back onto my delta yesterday!
I have relented, and put Repetier back, and want to resolve these issues.
1. I have set the height correctly (copied out of the working Marlin configuration.h) and have been trying to verify it in Repetier. What happens is that if I move the head down (g1 z10) and then jog it with the "Z" pad in Host is initially behaves correctly, but at about the 1mm point it suddenly crashed the head into the table. It's as if the movement has been multiplied by 10.
2. Auto level. This is weird, it starts off toward the z tower, checking in a line parallel to the x-z side. it then returns and starts again, moving still parallel to x-z towers. Does it again, but then attempts to leave the printable area, and triggers an error

The pattern seems to be a rhombus, but it errors out and the stored data attempts to put the bed centre right at the front of the bed.
The pattern looks like this:

What's going on?
