Hi all!
I have two reiden bf-1 3 axis machines.
Both are after repair. Both has servo powerboards replaced and now I have some doubts if machine needs to be recalibrated.

first machine:
I choose display axis results in LAG mode.
1.After testing all axis in manual mode in feedrate 2 m/min I see
X 0.66
Y0.66
Z 0.9
2.Testing by running nc program all axis lags are +/- equals (+/-5%)
electricity consumption differs maybe by 0.2A
Second machine:
Testing in manual mode (same feedrate)
all axis lag are identically the same, but when i run 3axis a program X axis lag is more by 15-16%


Is this normal? Does this LAG affects anything?

nx program I run is simple 3 axis linear movement program. all axis travel the same distance at the same speed.

Sory if I wrote in frong section and explained myself not clearly.
I am just programmer/operator and don't know all nuances and expressions
