Y axis not work, circuits integrated sanded

[josuesitan]

hi friends sorry for my bad English, I bought a Rabbit HX-3040 but came with the Driver burned chip,

in my experience come to the conclusion that it was a Driver L298, change it, but does not work.

I'm sure that's the right chip, but I can not change another circuit as it comes with tags deleted.

My question is if anyone has the schematic circuit for easy repair.

I can say I have some experience in electronics and CNC

Greetings and thanks.
