Thanks for the swift response lads, that gives me some insight to play around with today, I'll update later. Yeah Ger I'm using bottom left as origin in Aspire. The first time I came across this whole problem I thought 'Ahh this is an easy fix just use top left as my origin' but what this does is puts the piece into space outside the parameters of the machine and does not cure the fact that the piece is mirrored. This brings me to your observation Switcher, I think the XMAX and YMAX are related to the size of the piece as if I try to run a prog bigger than the size of the bed I get a limit switch message to say go back and edit a certain parameter.

Thanks Again
Mick

Update1: For sure the XMAX and YMAX are sheet sizes
