Actually that control box is a very effective CNC control box. It was developed by a very reputable company, and contains all the components to run a router/spindle/thc/torch, as long as the programming is done on the control box, which unfortunately is propietary. The benefit of the DY4000 control box is it is one unit, not seperate units, trying to work together. Most users of that box find it very conveinant to use, since resetting etc... is as simple as unplug, and pwr back up. It is too bad lowpull has to go through this because the control box is actually nice and easy to use, when the geckos are installed!
