    Maybe someone could be interested about the way i modified ground path around TB6560s in my 3 axis board, blue PCB.

    Here is the link to italian forum where i published same photos : http://www.cncitalia.net/forum/viewt...26754&start=10

    I also changed Fosc capacitor (pin 7 to ground) from 1nF to 100pF and, in conjuntion to step lines optocouplers bypass, now the board works flawlessy with Fstep of 50Khz.

    Yes, i know, datasheet reports 15Khz max ...

    But i don't mind about that.

    Marco.
