The Pulsar is actually a pre-production machine, with a few minor differences from the final production version, and I don't even recall what those differenecs are, other than slightly shorter travels. It is currently running with a SmoothStepper and UCCNC.
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?


I have not used either machine in probably 3 years. Don't think I've even powered them on!
Did you graduate to a better CNC mill?
