Your backlash is amazing. I have 2 thou backlash in Y and 6 thou in Z on my Torus (mechanically is a NM-145). Not really sure what my options are to rectify this.
Does your Pulsar have the upgraded base that can handle tons of coolant flow?
Did you graduate to a better CNC mill?I have not used either machine in probably 3 years. Don't think I've even powered them on!
