I've never used a HObbyCNC, but I have a Xylotex. Unless you're havine a problem due to your assembly of the board, I would think they should work about the same. The Xylotex does come assembled, just hook up your motors and power supply, and away you go. You'll probably need a 24V fan, the board has a connector for one. It just takes the 24V from your power supply. The Xylotex needs a fan blowing on the heatsinks. If you unplug a motor while the board is powered, it will die instantly. Same thing if a wire comes loose.
Jeff at Xylotex has great support. Just email him if you have any other questions about it.
