Hi everybody, and happy new year from France.
I bought a Super X2 a few weeks ago, and I want to transform it to a CNC machine.
Unfortunately, the DRV_XMT_500D(4) - very similar to the 500C(3) - burnt while I was testing maximum machine's speed.
The small diode bridge (D31) smoked, as the copper track beneath it.
I changed that bridge, and now the green light is on, but that's all.
So I'm looking for the schematics (220V) and any information, voltage reference, point of control,... that could help me to repair it.
Thanks in advance.

Well, I finally discovered that the SX3 driver board is nearly the same as mine...
And thanks to this page (http://www.cnczone.com/forums/x3-sx3...rol-sx3-6.html), I found the schematics I was looking for!
I hope I can repair it with that.

Incredible !
As I said before, I changed the small bridge rectifier, but that was not enough.
I decided to check different voltages on the board, but I had 0V everywhere!!
Finally I found that the main fuse had exploded too - the biggest piece was less than 1mm.
What annoys me the most is that in fact, the green light is connected before the fuse and not after it.
So when that light is on, you can't be sure the fuse is OK.
Bad design...

So I can again consider turning that machine to CNC.
