Different movement on X and Y

Hi Forum,

I have very interresting issue and would like get help from someone who may already have good experience.

Situation,
- X and Y is being used for same model of NEMA 34 and driver and same microsteps and configuration.
- X's Pncconf's test move table as it is but Y's Pncconf's test move not exactly as it will be
- after various combination of configuration params for Y, I cannot solved the situation.

One of my final test is chinging connect path
from X driver - X motor (move distance correct), Y driver - Y motor (move distance incorrect)
to     X driver - Y motor and Y driver - to X motor
and turn out Y's move distance still does not correct. 

by assmuing Y may need more torque, so I changed microsteps to low from 20(4000 sptes) to 8 (1600 steps) but it also does not works yet.

Would be great if someone share experience or any clue to make it correct.

Despite what you can read in many places, lowering the microsteps does _not_ give you more torque.
 

Andy, Thanks for confirming what I always thought but nobody else believed!
