1. The time has come to sell my 4 Axis TB6560 stepper motor driver board, as I have now reached the limits of this board, and now upgrading.

    I have been running this board at 28volts, and is as far as I am willing to push it.

    On my current setup I get a feed rate of around 500mm/min, using ASTROSYN MY103H702 1Nm Stepper Motors, and TR10x2 trapezoidal thread.

    These boards are still selling on eBay for around 50.

    Open to sensible offers, postage will be around 5 for UK mainland.

    If I don't get any interest in the next few days, I will put this up on ebay.

    Best Regards.

  2. Think you'll find the limiting factor is the motor not the board - these are high inductance motors. I have the same motors and even on 36v can't get more than 300rpm (600mm/min on TR10x2) on my small machine. If you want more speed its the motors you need to change not the board...
