    • Requires air extraction
    • Test location near rear rollerdoor?

    • Z-stepper current, set by DIP switches on the driver: raised to 4.3A, was peak-current 3.5A, (max is 7.8A)
      • Occasional stiction at 3.5A: acquire grease?
    • Level check bed: front RHS corner is up 2mm
    • Vent holes: any feedback?
    • Empty compressor tanks, water trap
    • Hour meter
