Im considering the following for converting an SPG 2217 111LV to CNC. Ballscrews are on order (5mm pitch), but what about drivers and steppers?

Thinking of either a gecko G540 or CNC4you 4.5A driver http://www.cnc4you.co.uk/index.php?r...&product_id=31 with their 4Nm steppers http://www.cnc4you.co.uk/index.php?r...&product_id=70 and the CNC4you breakout board.

Id love some feedback from anyone who has used them.

Cheers

Mark
