It happens right at the start. When I select the print, I get the standard "This file will override machine settings with setting from the slicer", which is nothing new, always had that with S3D sliced prints. The machine then heats up and just as it starts to move for printing, (head moves slightly out of home and back and the bed does the same) it stops and I get "ERROR: Tried printing out of printing area".
There is no pre-movement of the head before the machine heats up, like it does using Cura, it just heats up.
My starting script is as follows, never had a problem with Ultimaker firmware. I'm a Gcode biff so any advice gratefully received!
