run 1" for 1"

That you chose the correct step per unit

make noise

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

[tjfisher26]

ok so lower the velocity  and acceleration ?

[manmeran]

yes. It test with different amounts

[tjfisher26]

ok so that has fix the problem thanks alot manmardam  all i need to do now is slowly bring up the numbers and find the balance point

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.
