Sorry the DRV8825 didn't work out for you -- I've had no problems with them on breadboards, perf board, or my own shield design.

The Gecko G540 is made of four Gecko G250 drivers and their breakout board, all in one case. You shouldn't need any components other than the PC, a parallel cable, the Gecko itself, a power supply, motors, cables, and connectors. You need to install a resistor in the connector for each motor to set the current for that specific motor. See the G540 manual. That's the only external component you need. You can wire limit switches directly into the connector on the Gecko G540, and you can use the outputs to control the spindle.

Yeah I'm debating now if I should go the the gecko or what Damin69 is using.
