Thanks all,
Have had the printer a few week and its all up and runing very well.
Will leave the firmware well alone, not going to add BL or Fil out.
Just one more question, noticed that the V2 Meanwell psu has a fan outlet but the Enders black outer metal case plate covers over the air inlet slots on the Meanwells box ?
Wonder why the factory cover this airway up, surely not a good thing for a psu ?
Notice that folk who add and print a 3D cover to fit a larger fan also make new air vents to match etc.
