That you chose the correct step per unit

make noise

you must check "velocity" and "Acceleration"
i think These values were selected high level.

result :)

there will come a point where they start to misbehave, just back away from this by a few % and all should be well.

repeatability testing is next, sending the axes on a long journey around the table and making sure they return properly to where they started, but since I found the happy maximum speeds and accelerations for mine this has not been a problem.
