yes I will have a slave one.
but there is a very important thing that I discover right now... normally, I have a pulley of 20 teeth on the motor, 60 teeth pulley one the screw. so, normally, If I write Go X 10.0 , the motor should turn 3 times, and the screw one time in order to have 10 mm, machine moves 10 mm since I have a screw of 10 pitch.
but I found that the motor turns 3/4 turn, even not one turn when I write G0 X 10.0 . so there is some thing that does not work in the step per unit I guess.
what do you think?
