gmax 2 fails to be dimensionally correct

#1
printed the exact same part on all 3 of my printers ( gmax 2 lulzbot5 type a machines) and using the exact same filament on my gmax2 and type A machines i cant seem to get the part to print in the desired dimension.
The pictures below show the type a then the lulzbot then the 2 final ones being the gmax. where you can see its off by close to 11mm in size. tried re doing a gcode making sure i picked the correct printer and that wasnt the issue. not sure what is causing this failure.
