I mean play real ,mean put servo on spindle ( lath)

i know nothing about tapping and metal work
but i have question ,because taping its very precise spindle job,and its not regular lath job, i mean spindle not need now rotae one direction long time( can be flow memory)
( i belive you call the rotation spindle)why not use spindle as axiss? interpolation between axiss in mach work perfect

i also use absolute but not ethercat ,we read the value with rs485 by our application ,and homing we make as "at position"
what you ask i think its the origin like g54 g55... not home

only test on my laptop ,seem no any problem
ill test on machine later
***the segment are not so extreme short
     as i see its about 0.3-0.5 mm its quit normal we use this length a lot without any problem

I'll check tomaroow morningi also use only mm

Can you send me some curves oor dxf I'll try?

Can you show yours acceleration deceleration ,max speed parameters?

I didn't say it's because jerk ,I said because there no jerk in Mach4 you must put very very poor acceleration ,then the cv become strange behavior

1.as i see even in mach 3you have some problem with yours shape( final position not same as first)
2. i had a lot of problems with cv with mach4 i can suggest you: try increase the acceleration /deceleration
    but i can tell you from start this solution its problem because mach not support  jerk and its big problem with increase acceleration
    but for us this the only way we solve all that cv problems with mach4
