    Only guessing
    You have an A output(around X) in the programming... but you have a B axis (around Y) in the machine configuration.

    Re: Step Stancil

    Too fast (aluminium speeds), you are rubbing, not cutting.

    Try 65m/min (S3500), & feed of 0.05mm/tooth
    Neat oil may also make the cutter slip, not cut
    Soluble oil @ 6-10% concentration

    Re: Clamping Pressure For 304 SS Tubing

    Make a stepped bung to fit in the end, and if the OD is not to be machined... make soft jaws to avoid damaging the finish
    You could also make a stepped bung with centre for a tailstock centre.
