Strange behaviour on amesh scans
Using 2 mockup motors with big backlash I noticed that when doing a mesh the first lines are run quickly but after very slowly.
In fact it's because at each point of the fast motor, the slow motor moves to return at the same position ! But with a big backlash it takes many time.
Testing with different values I think it's a rounding issue either on mockup or axis.
step_per_unit is 1000 on m2
