Got a replacement board, and all fine now.
Need to troubleshoot extruder...
Out of the frying pan and into the fire!!

Thanks all

The extruder?

CTC supply a very simple plastic extruder which is not adjustable, and it has problems holding filament to feed.
Have ordered bowden extruder and e3d v6 clone, so hopefully will be ok.

Others have said original extruder is bad.

Turns out board on my CTC is a Geeetech clone, so problems when you try to install other Fw.
Will just buy genuine, as soon as i start my first bactch of upgrades...
