I think so that is what you said but what I think strange is : there is just one servormotor. I got a such problem and the encoder servomotors in longitudinal rail's parameters were differents , when they should be the same value. Now there is one motor and this is happening. Do you think that this problem can happen in this conditions? Why?
The machine cut sheet and the measurements of the parts cut are the same as set before.
So that I think that the enconder is not the problem...
