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?

Your steps per unit should be correct at 600 if your encoder is 500 line and your gearing 3:1 with 10mm pitch screws.
I presume your X is at 0 when you command that X10 move?

Not sure what is happening then unless the gearing or pitch or encoder count is not what you think.

Hi,
I found some thing in the encoder that the DIP of the encoer were all of them at position 1, but in the pdf , manual of the encoder, 2 of them should be on  and the position off.
I will try it and let you know.

Hello,
You are right Hood, the problem was in the encoder as you said. So I only changed the DIP switch of the encoder, adjusted the current limit of gecko 320x at only 9 o'clock  and every thing is OK.. 3 runs to achieve 10mm , so it is correct now. and also the speed. now the motor turns so fast I guess more than 1500 rpm. so every thing is OK for now.

thank you so much Hood and all the other members of the forum.
thanks again
Robhi
