Okay,

Great news have got the machine tuned to half step on the board switches with Steps/unit being between 135 and 148; mm/Min is between 225 (X,Z) and 560 on Y. acceleration works fine between 4 to 6 mm/sec/sec. Soft zero's and soft limits switches working fine tool input set up is going along just fine and very little heat on the unit.

NOW the PROBLEM, ther is NO, NONE, NADA, stepping motion in X at all. It will move fine under jog aand full power. Under stepping it does nothing but clicks in places. It is showing that it is trying but no go on the power to move at all. I am not sure what the problem is. Due to if it was the board the drivers on the Y axis should also be acting up. I have changed position of X zero in the machine to give it a bit better play and no joy. So will be trying a change in the g-code speed and upping it from 20% of full power to 40% and seeing how that goes for moving the X axis.

Wish me luck and any input would be well recieved.
