General Mach Discussion / i have a problem with servo Y axis motors

« on: May 03, 2009, 07:24:05 PM »

 hi everybody, hope you're ok

my name is tarik,i'm from morocco.

i'm beginner on cnc, and recently i purchased a cncrouter from a supplier,it got two servos in the Y axis.
the machine was sent to me with a pc with mach3 installed and programed already.
i assemble it and pluged it.
the machine has an enable  botton in the controller box they told me i have to push after pluging the machine. after that, a sound from the motors is heard, and they told me that's a feedbach from the motors to the controller box.
but this sound don't stop for Yaxis motors and when i try to jog with them, they make a sudden movement  just in their place and then they stop moving and the other axis too refuse to jog. no movement for all axis. and no sound too.

i cheched everything in mach and i don't thing that sth is wrong.
is it the motors that have some problem??
i tryed many times , i got the same result.
and i noticed also that the Y axis motors has become little bit hot at hand touch.i don't know if it's normal or not.
 
the supplier told me that they are not synched good.
how am i supposed to do so?

plz, if you have an idea about this kind of problems, help me.

thanks a lot.
