Done the calibration twice just to check, X-axis and Y-axis line up spot on. There is a two coloured square file included and that prints okay.
When i move the extruder gantry gently without power backwards and forwards in the Y-axis it feels a bit sticky and jerky, more so pushing it back than pulling it forewards.
Sent files to Technology outlet and they say the files print okay at their end, so I assume it's a problem with my machine.
Any way it's going back to Technology Outlet today.
