to be honest i did not switch it on again, i still have the board with the blown chip, i was just to scared something else blow . I replaced with the new board and did not get n response. no power going to the steppers (not locking up)

just asking, may be there is a fault still in the motor side blowing back to the board? when you get the new board, try leaving that motor not connected, see if you get movement on the other axis first, then power down and connect that motor, then power up again, what i would try to see if it would work. Good luck, or just build your self a new controller and beef it up a bit to handle your production requirements.

Sorry for the stupid question. How will i see if i get movement without the motor?
I wanted to build one but my knowledge is very limited with the electronics of cnc, what would i need?

i assume each IC there controls a different axis , so you could still move x and y if z was the faulty one before, not sure which one they had plugged into that IC,

As for building a new controller you would have to google a bit the software you are using, will it work with a arduino board, i used a ardunio mega 2560 with a ramps shied 1.4,

look here http://www.cnczone.com/forums/south-...cnc-forum.html, it is a bit over kill, but should just work fine, it was all plug and play.

What size motors are you using?

[kimb0]

small nema 17

[melvinbruce]

In that case with the nema 17 motors you could use a arduino uno or a mega 2560 and run from the shield board directly.

Like i siad they are sending me a new control box, but can i ask you for advice in the future please. The power supply is one of those round copper winding things. I am not sure were to get the power for 5volt from
