    That might be the answer. My Hitachi lists an input of 220V + or - 10% so I ended up with buck transformers to bring it down. Check your transformer or manual for proper input volts. 244V is just...

    Wild guess, does the VFD show any change when the M3 is issued?

    Maybe the signal is not getting to the VFD?

    Go with this. ^^^^^ Use a DCMT insert, CNMG's seem to chatter easier.

    Myself, if I value my time, would simply buy DOM or honed tube.

    Another way is to flush it with lots of air, as in large compressor, while taking the first cut.

    Typically springs are oil hardening steel.

    Temper to dark blue to grey on a polished section.

    I use A, B,and Z(or I) and ignore the /(or NOT) pins. Single ended works fine, don't need a converter.
