Carbide 3D's Shapeoko HDM V3 pairs HG15 rails and 16 mm ball screws with an 80 mm water-cooled spindle rated up to 2.2 kW, aimed at shops that cut aluminum.
FoxAlien's new XE-Ultra 8080 puts ball screws, linear rails, and closed-loop steppers on every axis for $1,799, but the spindle and spoilboard cost extra.
