What do you guys think is the better place for the z-axis motor? Direct drive sticking out the top of the column or inside the cowl with a timing belt? If inside the cowl, what gear ratio? If sticking out the column, do you cut a hole big enough in the cowl to slip the cowl over the motor or do you drill 4 motor mount holes and a driveshaft hole in the cowl and mount the motor after you put the cowl on?
