sakes lads ive just bought some flux but its hard stuff, will up load a pic in a mo. Im going to spend sat afternoon redoing these solders, thanks for explaining it in detail, I thought it balled due to me putting enough into the area and the solder had no where else to go so created the ball. Now I know this isnt the case and can revisit it with the knowledge of what im trying to achieve.

On another note, I want to buy new steppers a mine appear to be proper crap. Any recommendations for 3 motors that will fit my machine? budget of £120 for all 3?
