    also, there are jumpers that need to be changed on T3 as well.
    ...and T6 and T7.

    Anyone Re-Grind the Tailstock Taper

    My 10ee tailstock taper is pretty bad. i was thinking of buying a reamer to clean it up, but thinking it might be worth just having it reground. Anyone do this and can recommend a small shop willing...

    thanks, this is a huge help.
    yes, vfd is a Teco N3 and i have been running General Vector control and did run the auto tuning (A006=1). glad i got that correct :-)

    i am very frustrated that the motor shop made this mistake. it sent me on a wild-goose-chase buying another VFD and wasting a lot of time and $$$ looking for problems in the wrong places.
