Azteeg, Marlin, Kossel configure problem

I am making myself a Delta printer as cheaply as is possible. So far all is good with a total cost of around £60.

I have a configure problem and I cannot find if it is Marlin or Cura. I have gone through the Gcode looking for the culprit but can't find anything so I am hoping that someone has been down this road before me and can give me some pointers.

Attached video of the problem. At the end of every print the left front axis goes nuts and hammers against the end stop. I am assuming it is the end of the print but have no way to know. I cannot find anything that will let me see the Gcode per line as it is sent to the printer like I can in LinuxCNC.

Hmm, no surer way of solving a problem than posting it on a forum.

It is the pause at height plugin that is included when you install Cura that I have never used or adjusted but it decided was relevant with default settings that are 100 mm outside my build area.
